Intraperitoneal insemination of the guinea pig with synchronized estrus induced by progesterone implant. (1/818)

Female guinea pigs with synchronized ovulation by means of implantation of progesterone-filled tubing (P-tube) followed by a progesterone injection, were inseminated by intraperitoneal injection with sperm suspension. First, to obtain the optimum conditions for insemination, the females were inseminated singly over the range of 1-10 x 10(7) spermatozoa before and after the synchronized ovulation. The incidence of conception and implantation was 100% in the females given more than 5 x 10(7)/animal at 9:00 h on the 5th day after removal of the P-tube. Second, the reproductive ability of the inseminated females under this optimal condition was observed throughout the pregnancy to delivery. Inseminated females had a mean +/- S.D. gestation period of 68.7 +/- 0.5 days, a litter size of 2.8 +/- 0.6 pups and body weight of 110 +/- 14 g. These data were comparable to those of naturally-mated females. Our findings suggest that the artificial insemination by intraperitoneal injection in combination with the synchronized estrus technique is very useful for production control in a small colony of guinea pigs.  (+info)

Characterization of uterine leukocyte infiltration in gilts after artificial insemination. (2/818)

The objective of this study was to characterize the uterine leukocyte influx after artificial insemination (AI). After detection of oestrus with a boar at intervals of 1.5 h, seventy-two gilts were randomly assigned to a 2 x 3 x 4 factorial arrangement. AI was performed with 100 ml extended semen containing 5 x 10(9) spermatozoa (semen; n = 36) or 100 ml VSP semen extender (extender; n = 36) at one of three times after detection of oestrus: 12, 24 or 36 h (n = 24/time). The uterus was lavaged at 6, 12, 18 or 24 h (n = 18/time) after AI to determine the total number of uterine leukocytes. In addition, uterine lavage was performed on nine untreated gilts immediately after the detection of oestrus to establish a baseline number of leukocytes. The leukocyte response in all samples consisted predominately (92-99%) of polymorphonuclear neutrophilic granulocytes (PMNs). The mean number of PMNs recovered from the uteri of gilts treated with semen was greater than in gilts treated with extender and in untreated gilts (P < 0.01). The greatest number of PMNs in semen-treated gilts was found 12 h after AI (P < 0.01), and this number was sustained for 24 h. In contrast, the number of uterine PMNs recovered from extender-treated gilts reached a peak at 6 h and had declined by 12 h after AI (P < 0.05). It was concluded that an extensive influx of PMNs into the uterus is a normal sequence to AI. The consequences and importance of semen-induced uterine leukocytosis needs further investigation.  (+info)

Sperm migration into and through the oviduct following artificial insemination at different stages of the estrous cycle in the rat. (3/818)

In order to examine whether sperm migration into and through the oviduct follows an invariable pattern or is subject to regulation, rats in proestrus, estrus, metestrus, or diestrus were inseminated in the upper third of each uterine horn with 10-20 million epididymal spermatozoa. Three or eight hours later, the numbers of spermatozoa free and adhering to the epithelium in the ampullary and isthmic segments were determined. A significantly higher number of spermatozoa were recovered in estrus than in other stages, at 3 h than at 8 h, and at all stages from the isthmus than from the ampulla. Spermatozoa adhering to the epithelium were observed only in proestrus and estrus and in the isthmus. The effect of exogenous estradiol-17beta (E2) and progesterone (P4) on sperm migration was investigated in rats in which the estrous cycle was inhibited pharmacologically. E2 facilitated sperm migration into the oviduct and P4 antagonized this effect, whereas P4 alone had no effect. Concomitant treatment with E2+P4 induced adhesion of spermatozoa to the oviductal epithelium. In conclusion, the pattern of sperm migration into and through the rat oviduct varies with the stage of the cycle, being dependent on E2 and P4. The adhesion of spermatozoa to the rat oviductal epithelium is stage- and segment-specific and requires the combined action of both hormones.  (+info)

Serum progesterone in predicting pregnancy outcome after assisted reproductive technology. (4/818)

PURPOSE: Our purpose was to determine whether serum progesterone predicts pregnancy outcome after superovulation. METHODS: One hundred twenty-three consecutively pregnant patients were divided into three groups: group I, 55 patients following superovulation for assisted reproductive technologies; group II, 23 patients after correction of oligoovulation; and group III, 45 patients who conceived spontaneously. When beta-human chorionic gonadotropin was positive, progesterone was measured on the same serum sample. A serum progesterone level of 45 microns/L was set to differentiate between nonviable pregnancy and ongoing pregnancy. RESULTS: In group I, zero (0%) of 38 ongoing pregnancies and 10 (59%) of 17 nonviable pregnancies were observed with a progesterone level of < 45 microns/L [14.2 ng/ml (P < 0.001)]. In group II, 4 (27%) of 15 ongoing pregnancies and 5 (63%) of 8 nonviable pregnancies had a progesterone level of < 45 microns/L (P = NS). In group III, 10 (42%) of 24 ongoing pregnancies and 15 (71%) of 21 nonviable pregnancies were observed with a progesterone level of < 45 microns/L (14.2 ng/ml) (P = NS). CONCLUSIONS: A serum progesterone level of < 45 nM predicts nonviable pregnancy after superovulation for assisted reproductive technology.  (+info)

Status of genomic imprinting in mouse spermatids. (5/818)

The advent of human round spermatid microinjection (ROSI) into oocytes as a treatment for severe male infertility raises the question of whether spermatids have undergone all of the maturation processes necessary for normal development. It is particularly important to know whether spermatids have undergone correct genomic imprinting, which results in the parent-of-origin-specific expression of only one allele of a gene. We assessed the imprinting status of three maternally and three paternally expressed genes in interspecific hybrid embryos generated by injecting Mus castaneus spermatids into Mus musculus oocytes. We used the single nucleotide primer extension (SNuPE) assay to measure the relative expression of maternal and paternal alleles on the basis of sequence polymorphisms in the transcripts. Expression of imprinted genes in mouse embryos derived by ROSI did not differ from controls, indicating that paternal genes have undergone proper imprinting by the round spermatid stage.  (+info)

Estrus synchronization of beef cattle with a combination of melengestrol acetate and an injection of progesterone and 17beta-estradiol. (6/818)

Our hypothesis was that estrus synchronization in beef cattle using melengestrol acetate (MGA) and an injection of progesterone (P4) and 17beta-estradiol (E2) to regress dominant ovarian follicles would improve pregnancy rate (number conceived/number in group) to AI compared with feeding only MGA or injecting PGF2alpha. During 2 yr, peripubertal heifers (n = 52) and cows (n = 327) received either 1) MGA for 18 d (d 0 = 1st d of MGA) plus an injection of P4 and E2 in sesame oil (vehicle) on d 11 to regress persistent ovarian follicles (MGA+P4), 2) MGA for 18 d plus vehicle on d 11 (MGA), or 3) two injections of PGF2alpha 10 d apart (d 7 and 17, PG). Concentration of P4 was assessed in blood samples obtained on d 0, 7, and 17 to indicate estrual status (anestrual or estrual) during treatment to induce estrus synchrony. Observations for detection of estrus occurred every 6 h for 180 h following treatment cessation. Females showing estrus were inseminated 6 to 12 h after estrus detection. Conception to AI was determined by ultrasonography 35 to 40 d later. Conception rate was greater (P < .05) in females in the PG than in those in the MGA group but did not differ from conception rate of females in the MGA+P4 group. Among anestrual females, estrus synchrony rates were greatest (P < .10) among females treated with MGA+P4. Among females that were estrual before treatment cessation, estrus synchrony rates were greater (P < .10) among females treated with MGA+P4 or PG than among those given MGA. Pregnancy rates were greater (P < .05) among females that were anestrual before treatment cessation and treated with MGA or MGA+P4 than among those treated with PG. Estrus synchronization using MGA+P4 and E2 differentially improves estrus synchronization and pregnancy rates among anestrual and estrual beef cattle while maintaining conception rates similar to those of PGF2alpha-treated females.  (+info)

The nucleus of round spermatids, the earliest haploid male germ cells, can participate in the formation of normal zygotes when incorporated into activated oocytes. In this study, we injected mouse round spermatids into homologous mature oocytes that were kept arrested at metaphase II to induce premature chromosome condensation (PCC) of the spermatid nuclei. After full condensation of the spermatid chromosomes, the oocytes were activated by Sr2+-containing medium, into which cytochalasin B was added to prevent extrusion of the segregated female and male chromosomes as polar bodies. Out of 142 oocytes examined, 104 (73%) formed two male (pseudo)pronuclei and two female pronuclei. To restore the diploid state of these zygotes, one of the female pronuclei was removed. When cultured in vitro for 72 hours, all (n = 37) of the constructed embryos developed to the morula/blastocyst stage. When 2-cell embryos and morulae/blastocysts were transferred into pseudopregnant females, 14 (13/96) and 24% (9/37), respectively, developed into term offspring. This study indicates that the spermatid chromosomes, which had undergone PCC, moved safely to opposite poles after oocyte activation. Since round spermatids contain no (in the mouse) or little (in patients with spermatogenic failure) oocyte-activating factor, this method may be used to rescue oocytes that fail to be activated at the time of spermatid injection.  (+info)

Duration of estrus in relation to reproduction results in pigs on commercial farms. (8/818)

This research was conducted to determine factors that influence duration of estrus, AI strategy, and reproduction results between and within commercial swine farms that use AI. Data from 15,186 sows and gilts on 55 farms for a period of 6.1+/-4.2 mo per farm were used in this study. The average duration of estrus was 48.4+/-1.0 h, ranging from 31 to 64 h, and was consistent from month to month within a farm (repeatability of 86%). Differences in duration of estrus between farms accounted for 23% of the total variation in duration of estrus. On most farms (n = 45), gilts showed a shorter (P < .05) duration of estrus than sows (40.8+/-1.1 h vs 48.5+/-1.0 h). The duration of first estrus after weaning was longer (P < .0001) compared with that of repeat-breeder sows (50.2+/-1.0 h vs 46.8+/-1.0 h). Duration of estrus decreased (P < .05) when interval from weaning to estrus increased from 4 to 6 d (56.0 +/- 1.2 h vs 45.8 +/-1.2 h). The regression of interval from onset to estrus to first AI and interval from weaning to estrus varied between farms and ranged from -7.4 to +1.3 h/d; four farms had a positive relationship. Farrowing rate decreased (P < .05) from 89.7+/-2.7% to 78.2+/-5.74 when the interval from weaning to estrus increased from 4 to 10 d. The litter size decreased (P < .05) from 11.7 to 10.6 pigs when the interval from weaning to estrus increased from 4 to 7 d. Compared with a single AI, double AI in sows and gilts resulted in a 4.3 and 7.0% higher (P < .05) farrowing rate, respectively. When the first AI was performed after expected ovulation, reproduction results were lower than when AI was performed before or at expected ovulation in sows. Duration of estrus was not related to farrowing rate or litter size in individual pigs. Number of inseminations per estrus, time of AI, and duration of estrus were correlated, which made it difficult to assess which of these factors was primarily related to the farrowing rate or litter size. Knowledge of average duration of estrus on farms and of factors that influence the duration of estrus on commercial farms can help to improve the efficiency of the AI strategy specific for each farm.  (+info)

The dairy industry spends an inordinate amount of money telling us we need to drink milk. simpler insemination techniques for sheep and goats have enabled farmers to carry out artificial insemination on their animals themselves. the most limiting factor in artificial insemination programs is the proper detection of cows or heifers in estrus. however, success of any ai program requires attention. although artificial insemination (ai) of cattle has been possible for 60 years, this technology has not been used widely in the canadian beef industry. the breeding artificial insemination in animals program may use either artificial insemination (ai) or natural service. huge collection, amazing choice, 100 million high quality, affordable rf and rm images. our adelaide hills based practice has a special interest in equine dentistry, equine artificial insemination, cattle medicine, small animal medicine and pet grooming livestock :: the artificial insemination of farm animals. advantages & disadvantages ...
Development of novel laparoscopic artificial insemination equipment Ting-Chieh Kang. The aim of this study was to evaluate the performance of three different types of laparoscopic artificial insemination tubes. In the first experiment, we compare the cost, operation time starting from thawing of frozen semen to ready for insemination, and the pregnancy rate, delivery rate, average litter size after laparoscopic artificial insemination. Results showed that the cost and operation time for Germany, French, and self-made tube was 375, 150 and 150 NTD, and 120, 95 and 70 sec, respectively. In addition, laparoscopic artificial insemination with 75 × 106 spermatozoa/mL by using the Germany, French, and self-made tube resulted the pregnancy rate (at day 45 post insemination, detected by ultrasonic) of 38, 57, and 50%, with the delivery rate of 100, 75, and 100%, and the average litter size of 1, 2.3 and 2. In the second experiment, we use self-made tube to inseminate into three different position of ...

Pioneering work by Quinn and Burrows in the late 1930s led to successful artificial insemination (AI) programs in the domestic poultry industry. A variety of species specific modifications to the Quinn and Burrows massage technique made AI possible in nondomestic birds. Massage semen collection and insemination techniques span the entire range of species from sparrows to ostriches. Also, cooperative semen collection and electroejaculation have found limited use in some nondomestic species. Artificial insemination produces good fertility, often exceeding fertility levels in naturally copulating populations. However, aviculturists should explore other ways to improve fertility before resorting to AI. Artificial insemination is labor intensive and may pose risks to nondomestic birds as well as handlers associated with capture and insemination. Semen collection and AI makes semen cryopreservation and germ plasma preservation possible. Yet, semen cryopreservation techniques need improvement before fertility
The programme which has been rolled out through a partnership between government and the European Union comes after it was established that there are few bulls compared to cows and heifers.. The process is also set to improve the quality of animals through the selection of high breed bull shots to transform the national herd that currently has fewer high breed animals.. We are encouraging and training farmers to adopt artificial insemination to enhance the national head to 6million.. Research officer at the Institute, Mrs Grace Tambo says artificial insemination is an effective way of increasing the national herd whose target is 6 million..

NICE is currently consulting on an Addendum to the Fertility Guidelines (No 156) relating to intrauterine insemination. The summary of the rationale for the consultation is as follows: NICE published a guideline on the assessment and treatment of fertility problems in 2004, and this guideline was updated in 2013 As part of the 2013 update, recommendations on the use of intrauterine insemination were changed. Concerns were raised about the process that was followed when the recommendations about intrauterine insemination were discussed by the Committee during the 2013 update. This update will reconsider the evidence for intrauterine insemination, with or without ovarian stimulation, compared with expectant management for people with unexplained infertility, mild endometriosis and mild male-factor infertility and whether the 2013 recommendations should be updated.. NICE Addendum to Clinical Guideline 156.Draft for Consultation.2016. BFS will submit a ...
Artificial insemination begins with the collection of semen through masturbation, after 3-5 days of sexual abstinence, and placing the sample in a sterile container to assess the quality and quantity of sperm. Only semen with the following characteristics can be used: volume above 2 mL, pH from 7.2 to 7.8, concentration above 20 million sperm / mL, more than 50% of freely moving sperm and more than 30% of sperm with natural shapes.. About 3-7 days before the day of insemination happens the woman must take an ovulation inducer, such as clomiphene, and 2 additional doses of hCG are still needed 3-6 days after insemination.. The artificial insemination happens as follows: the doctor inserts a vaginal speculum (similar to the one used in the pap smear) and removes the excess cervical mucus present in the womans uterus, then the sperm is deposited. After that the patient must rest for 30 minutes and up to 2 inseminations can be done to increase the chances of pregnancy.. Usually, pregnancy occurs ...
Insemination with donor spermatozoa is an integral part of infertility treatment. For the last 3 years in our unit, intrauterine insemination with donor spermatozoa (IUID) has been used in preference to vaginal insemination. In this retrospective study, patients were offered an initial course of five single intrauterine inseminations with cryopreserved donor spermatozoa and treatment was then reviewed. A total of 389 patients received 1465 inseminations. In all, 1119 cycles were monitored using luteinizing hormone serum analyses and 346 cycles using the urine home test kits. The clinical pregnancy rate per insemination for the cycles monitored by the serum assay was 18.0% (202/1119) compared with the urine cycles (13.7%, 46/346) (P ,05). The pregnancy loss rate was not significantly different (14.4%, 29/202 and 21.7%, 10/46) (serum and urine cycles respectively). The viable clinical pregnancy rate was significantly higher (P ,03) for the serum cycles than for the cycles using the urinary ...

The cost of frozen semen insemination is high. The results expected with frozen semen is lower than when using fresh semen. This is even more so when it becomes evident that the frozen semen used is of very poor quality. Unfortunately the veterinarian that has to inseminate the semen is often confronted with the reality that the frozen semen that they thawed does not nearly meet the progressive motility than stated on the paperwork. Unfortunately this fact is only realised on the intended day of insemination. The probability of singleton litters and two pup litters are also somewhat higher than normal. Therefore in all cases we strongly advise the use of a top-up male after the last insemination with the frozen semen. Given the fact that frozen thawed semen is unable to fertilize 12 hours following its deposition into the uterus, it makes perfect sense to inseminate the bitch (through the vagina) using fresh semen at least 12 hours after the last frozen semen insemination but before the bitch ...

Intracervical insemination (ICI) is painless and is the easiest and most common insemination technique. It closely replicates the ejaculation of semen by the penis into the vagina during intercourse. ICI involves the introduction of unwashed or raw semen into the vagina at the entrance to the cervix, usually by means of a needleless syringe. It is the simplest type of artificial insemination, and unwashed or raw semen is normally used, but semen supplied by a donor through a sperm bank which has been prepared for IUI use may also be used. The procedure is commonly used in home, self-insemination and practitioner insemination procedures, and for insemination where semen is provided by private donors. In order to perform an ICI insemination, air must be expelled from a needle-less syringe which is then filled with semen which has been allowed to liquify. Any further enclosed air must be removed by gently pressing the plunger forward. The woman lies on her back and the syringe is then inserted into ...

BACKGROUND Although FIVET and ICSI efficacy and efficiency are continuously increasing, intrauterine insemination (IUI) is a very used technique for many different types of sterility. It is also used in male sterility for its cost/benefit positive rate. Pregnancies frequency obtained after IUI in male factor infertility cases, with or without ovarian stimulation, shows the value of this work. METHODS We evaluated 149 insemination cycles in 34 couples with a male infertility diagnosis confirmed after at least 2 semen analysis, according to OMS criteria. All the 34 patients had at least one Fallopian tube open and some spontaneous ovulatory cycle to enter in this study. The patients without biochemical pregnancy signs after 6 intrauterine insemination cycles were induced to multiple ovulations through oral administration of 50 mg of Clomifene citrate from the 5th to the 9th cycle-day or through intramuscular administration of 75 I.U. of FSH from the 5th cycle-day. A luteal support with 200 mg of vaginal
Cliff Lamb, University of Florida - North Florida Research and Education Center, Marianna, FL. Estrous synchronization (ES) and artificial insemination (AI) are reproductive management tools that have been available to beef producers for over 50 years. Synchronization of the estrous cycle has the potential to shorten the calving season, increase calf uniformity, and enhance the possibilities for utilizing AI. Artificial insemination allows producers the opportunity to infuse superior genetics into their operations at costs far below the cost of purchasing a herd sire of similar standards. These tools remain the most important and widely applicable reproductive bio-technologies available for beef cattle operations (Seidel, 1995). However, beef producers have been slow to utilize or adopt these technologies into their production systems.. Current research has focused on the development of methods that effectively synchronize estrous in postpartum (after calving) beef cows and replacement beef ...
The objective of this study was to compare the effect of human chorionic gonadotrophin (hCG) and gonadotropin releasing hormone (GnRH) administration on day 5 after artificial insemination (AI) on luteal function. Thirty-three dairy cows were synchronized by the Ovsynch protocol and assigned randomly into 3 equal groups to receive on day 5 after AI 1500UI hCG, 100µg GnRH, and 2mL saline solution (Control), respectively. progesterone concentration (P4) in blood was measured every 3 days from day 5 to 23 after timed AI. Ultrasound examination of ovaries was performed on days -10, 0 (day of AI), 2, 5, 8, 11 and 14. The results revealed a development of an accessory corpus luteum(CL), 100% in the group received GnRH and 90.9% in that received hCG. No accessory corpus luteum in control group was observed. Total luteal tissue area on the ovaries was increased in hCG and GnRH group compared to control. Plasma P4 concentration was significantly (P , 0.05) higher in hCG and GnRH groups than control ...
IUI Attempts. Before trying other forms of assisted reproductive technology (ART), a couple should at least try three attempts of intrauterine insemination. For a female age 40 years or older, or a woman with a low ovarian reserve, IVF should be considered after 1-2 failed IUI attempts. In vitro fertilization has a higher success rate than IUI, so many couples choose to move on to this procedure when IUI fails.. Third Party Reproduction. IUI can be done using donor sperm, which is called donor insemination. Use of another mans sperm is done when the male partners sperm quality is so severely damaged that it cannot be used for IUI or in vitro fertilization. Donor insemination is also an option for single women and lesbian couples who wish to have a baby.. With several fertility centers in Irvine, Glendale, Torrance and Corona, Pacific Reproductive Center provides comprehensive IVF and IUI treatments with incredible success rates. Call us Today!. ...
Intracervical insemination (ICI) simulates the ejaculation of semen by the penis into the vagina during intercourse. It is painless and is the simplest, easiest and most common method of artificial insemination. ICI involves the introduction of unwashed or raw semen into the vagina at the entrance to the cervix, usually by means of a needleless syringe. ICI is commonly used in the home, by self-insemination and practitioner insemination. Raw semen from a private donor may be used for ICI. Semen supplied by a sperm bank prepared for ICI or IUI use is suitable for ICI. It is a popular method amongst single and lesbian women purchasing donor sperm on-line. Since ICI is the method of insemination most closely resembling the effects of sexual intercourse, it is less effective than, for example, IUI where sperm is deposited directly into the uterus, but it still offers a recipient the opportunity to achieve a pregnancy without direct physical contact with the male whose semen is used. It may also be ...
Intrauterine insemination (IUI) - a type of artificial insemination - is a procedure for treating infertility. Sperm that have been washed and concentrated are placed directly in your uterus around the time your ovary releases one or more eggs to be fertilized. Older types of artificial insemination placed the sperm in the vagina. While this was easier, it was not as successful as the current procedure.

Ewes are seasonally polyestrous short-day breeders with an estrous cycle of approximately 16 - 17 days. In the northern hemisphere ewes have active estrous cycles and are naturally receptive to rams from late September to late December when there is less than 12 hours of daylength. However, progressive sheep breeders often prefer to breed sheep earlier in the year, during periods where there is more than twelve hours of daylength, (July and August) in order to have lambs that are appropriate to target specific show markets. In order to facilitate this out of season breeding and accelerate genetic gain, producers rely on Assisted Reproductive Techniques such as Laparoscopic Artificial Insemination (LAI), ovarian hyper-stimulation, embryo collection from valuable embryo donors, and embryo transfer (ET) into synchronized recipients (1,2,3.) This field trial was conducted during late July through early August in southwest Virginia (latitude 36-3812 N), during a daylight period of about 14 hours. ...
Intrauterine insemination (IUI) is one alternative for couples undergoing infertility treatment. This procedure is performed to improve a womans chance of getting pregnant. It has been shown that conception rates per attempt are improved if IUI is performed. It is a very commonly performed procedure and is considered a standard part of fertility treatment.. For a woman to get pregnant, a mans sperm must travel from the vagina through the cervix (the narrow, lower part of the uterus), into the uterus and up into one of the fallopian tubes. If sperm arrives in the tubes soon after the release of the egg from the ovary (ovulation), the sperm and egg can meet in the tube, most commonly on the side that ovulation took place, and fertilization may occur.. Because the cervix naturally limits the number of sperm that enter the uterus, only a few sperm actually make their way to the fallopian tubes. Intrauterine insemination is a procedure that bypasses the cervix and places sperm into a womans uterus ...
Intrauterine insemination (IUI) is a procedure which involves injecting sperm into a womans uterus to facilitate fertilization. IUI may be performed both during a natural (unmedicated) or medicated cycle. During a medicated cycle, the woman receives drugs to help stimulate the ovaries & encourage egg production.

Improving Artificial Insemination Techniques. Use of incorrect A.I. techniques can lower the overall success rate of the A.I. breeding program. At one time, most producers learned correct techniques in semen handling and insemination procedures, but, unfortunately, many have developed some bad habits. Reviewing proper procedures should help eliminate some of those common mistakes.. Maintenance of Semen Tank and A.I. Equipment. Keep semen tanks in a secure, clean, dry place away from corrosive chemicals. Your tanks location should allow for easy moving for filling with liquid nitrogen. Store tanks in a visible place, and frequently monitor the nitrogen level. Only store about a 6-month supply of semen. Make sure your investment is insured and secure.. Always check the semen inventory list before removing semen from a tank to make sure each time that the correct canister is used. Do not lift semen above the frost line in the neck of the nitrogen tank. Dangerous temperatures exist in the upper ...
Ovulation is triggered mainly by two types of medications; HCG, which is available as Ovidrel, Gonasi or Pregnyl and Suprecur which is an analogue trigger. Both triggers act in different ways. The HCG trigger mimics the LH hormone (the hormone that starts the process of ovulation). When we look at the efficacy of this, often in IVF, we use an analogue trigger to lower the incidence of ovarian hyperstimulation syndrome. Though when we use this trigger, we know that freezing of embryos gives us a much better pregnancy rate, while using HCG gives a much better pregnancy rate during a fresh cycle.. Often it is asked, what if we give this during an intrauterine insemination cycle and use a Suprecur trigger when a woman gets more than three or four follicles? A study published in Fertility and Sterility in 2017 looked at randomising women who were given the analogue trigger which is Suprecur, and doing IUI along with an HCG trigger, and what that demonstrated is that even when nature was used to its ...

It is the time of year in the Midwest when breeding soundness exams and artificial insemination programs are everyday events. Great strides have been made in the last few years in the design and products available that make use of timed AI programs not only easy to implement but highly effective. We use timed AI programs routinely in our practice. In beef herds there is a huge savings in labor due to the convenience of being able to pre determine weeks in advance what day the herd will need to be gathered for chute work. This tool has allowed us to implement AI in commercial herds that would not have heat detected and bred after observed heats. The convenience factor of AI in my opinion is seen on both ends of gestation. It is a huge advantage to have 60% of your cows bred on day 1 of the breeding season strictly for labor and convenience. There are also economic reasons why this is beneficial. If you are able to breed 60% AI (I tell my producers to hope for , than 60 but to expect 60 or ,) and ...
Reduction in the frequency of undesirable recessive genes is examined for several combinations of initial gene frequencies and number of offspring obtained by random mating of young sires to the population. Only sires not having affected offspring are then returned to heavy use. Such selection can very rapidly reduce the number of affected offspring, if the initial gene frequency is high or if the number of tested offspring is 200-500 for lower gene frequencies. For some combinations, frequency of affected offspring in the population is higher after two or three generations of selection than in the first generation of selection. With high initial gene frequencies, practically all heterozygous males are detected and culled during the test period, resulting in practically no affected offspring in the first generation. The population gene frequency remains relatively high, due to the influence of the unselected females. In the next generation the heterozygous males are not detected with high probability

Current artificial insemination (AI) laboratory practices assess semen quality of each boar ejaculate to decide which ones to process into AI doses. This decision is aided with two, world-wide used, motility parameters that come available through computer assisted semen analysis (CASA). This decision process, however, still results in AI doses with variable and sometimes suboptimal fertility outcomes (e.g., small litter size). The hypothesis was that the decision which ejaculates to process into AI doses can be improved by adding more data from CASA systems, and data from other sources, in combination with a data-driven model. Available data consisted of ejaculates that passed the initial decision, and thus, were processed into AI doses and used to inseminate sows. Data were divided into a training set (6793 records) and a validation set (1191 records) for model development, and an independent test set (1434 records) for performance assessment. Gradient Boosting Machine (GBM) models were ...
Timor deer (Cerrnus limoremis) is the native tropical deer in Indonesia and is one of 20 wild animals which have been domesticated fairly recently for meat production (Kyle, 1994). As a newly domesticated fm animal which is highly potential and prospective as a source of animal protein, efforts should be taken into account to increase its population and productivity through the application of appropriate reproductive technology, particularly artificial insemination (Al). Prerequisite for the application of A1 technology in timor deer is an intensive study of its biology of reproduction. A series of research activities have been conducted to study the biology of reproduction and AI of the tirnar deer, encompassing the pattern of antler developmental cycle in relation to testosterone hormone profile and sperm production of the stag, anatomy of reproductive organs of the stag and hind, semen characteristics. preservation, and cryopreservation of the tirnor stag semen, estrous cycle and profile of ...
Experiments on the physiology of the spermatozoon are in progress in which artificial insemination is used as a test of fertility. One of the variables which enters into the technique is the number of spermatozoa introduced into the vagina of the female. This number will depend upon the density of the suspension (i. e., the number of spermatozoa per cubic centimetre) and the volume. The following experiments were undertaken to test the effect of varying the density of the suspension, the volume being constant. Apart from solving a problem of technique it was hoped to gain information on some of the factors which affect fertility or sterility under normal breeding, since it is conceivable that here also the number or density of the ejaculated spermatozoa may play a part. ...

Geese are seasonal reproductive animal from Oct. to Mar. next year. Geese dividing into individual cage for breeding study are needed. It is also need a lot of labor for the breeding study. The purpose of this study was to develop an artificial insemination shelf to save labor. The result showed that we need only a person for semen collection using the shelf for gander semen collection, but the traditional method three people were needed. The shelf was also tried to use on female geese for artificial insemination. The female geese were also can be fixed well by the shelf. But it still has some problems on the female artificial insemination. ...
To evaluate an artificial insemination program in postpartum Bos indicus cows and by using deterministic models, to estimate the possible economic advantages of insemination by appointment over detected estrus, sixty-three multiparous animals were synchronized using a progestagen device inserted at day 31 and withdrawn after 9 days (average time for withdrawal was 40.9 ± 6.8 days). Cows were observed continuously from 0700 to 1800 during 72 h. The percentage of animals detected positive to estrus by riding behavior was 43.4%, transrectal palpation, 22% and heat detector patches, 4.6%. The percentage of cows ovulating as evidenced by progesterone samples taken at 9 and 11 days after the average estrus response was 73%. The economical assessment by using the values obtained in the present study afforded that the cost of semen, ovulation rate and fertility point to a definitive advantage of using AI at fixed time over a program based on estrus detection.
Many tools are available to the fertility specialist for treating male infertility.In mild cases, super-ovulation (a procedure in which the wife is given fertility drugs to stimulate formation of multiple eggs, thus increasing the possibility that any one will fertilize) with Intrauterine Insemination (IUI). With IUI, the husbands semen is washed, capacitated and concentrated and then injected directly into the uterus. When auto-immune factors are present, the sperm are first purified in a technique called sperm washing.. In Vitro Fertilization (IVF) is also frequently utilized to treat severe male factor infertility or in cases where superovulation and insemination has not been successful.. Recently, two high-tech breakthroughs have increased the odds significantly for couples with severe male infertility undergoing IVF:. Utilizing ICSI (pronounced icksy), which stands for IntraCytoplasmic Sperm Injection, a single sperm is all that is needed. It can be injected, using microscopic ...
article{8500859, abstract = {The aims of our field study in dairy cows were (1) to consolidate cytotape (CT) as a valid technique to diagnose cytological endometritis (CYTO) during artificial insemination (AI); (2) to establish a cutoff point concerning the polymorphonuclear cells (PMN) proportion to diagnose CYTO at AI; (3) to assess the prevalence of CYTO at AI; and (4) to evaluate the effect of CYTO on the pregnancy outcome of that AI. The investigation was performed using 1,625 AI-CT samples harvested from 873 Holstein-Friesian cows from 18 dairy farms in the Flemish region of Belgium. The CT device consisted of adapting a 1.5-cm piece of paper tape on the top of a conventional AI catheter covered with a double guard sheet, allowing an endometrial cytology sample to be taken when performing an AI. A receiving operator characteristic curve was built to assess the threshold level above which the PMN proportion significantly affected the AI success. Multilevel generalized mixed-effect models ...
Artificial Insemination. Artificial Insemination (AI) is a deliberate injection of spermatozoa into oviduct for the purpose of achieving a pregnancy through fertilisation by means of other than copulation. Artificial insemination is a common practice in the breeding of cattles to increase the number of animals like cows, sheeps, and etc. For rhinos, AI is a relatively new reproduction technic - this technic was first implemented in Hongaria in 2006 - yet, it has been implemented frequently to rhinos. SRS, through this breeding program, has applied Artificial Insemination method to female rhinos (namely Bina and Rosa) and will probably apply it to another rhino (namely Ratu). As already known, Bina and Rosa havent bred yet during their staying in SRS.. Andalas semen collection. Male Sumatran Rhino, Andalas, has been proven to be productive and able to produce good quality of spermatozoa. Within one year, SRS has successfully collected Andalas semen for 80 straws and stored it in nitrogen liquid ...
Intrauterine insemination (IUI) is one of many treatments provided to infertility patients. Many factors such as, but not limited to, quality of semen, the age of a woman, and reproductive hormone levels contribute to infertility. Therefore, the aim of our study is to establish a statistical probability concerning the prediction of which groups of patients have a very good or poor prognosis for pregnancy after IUI insemination. For that purpose, we compare the results of two analyses: Cluster Analysis and Kohonen Neural Networks. The k-means algorithm from the clustering methods was the best to use for selecting patients with a good prognosis but the Kohonen Neural Networks was better for selecting groups of patients with the lowest chances for pregnancy ...
The growing infertility has caused an increase in the number of patients who opt for artificial insemination in Azerbaijan, Zinyat Muradova, an official of the Scientific-Research Institute of Obstetrics and Gynecology under the Ministry of Health, told APA. She noted that the causes of infertility are different. In our country, the cases of infertility are most associated with men. Infections in men and their way of life can be indicated as the causes of infertility, added Muradova.. According to her, one of the key points of the correct course of pregnancy is the timely identification of risk factors (socio-biological, obstetric-gynecological and extragenital factors).. Biological factors include the age of mother and father, bad habits, body weight, while gynecological factors include miscarriages, caesarean surgery, infertility and others, and extragenital factors include detection of urine, lung, cardiovascular diseases. If these are not detected in a timely manner, pregnancy may end. If ...

Scientists have been able to use artificial insemination to bring 97 shark pups to life, a new study published in Scientific Reports revealed, in what a release describes as the largest-ever effort to artificially inseminate sharks.
BACKGROUND: Improving the reproductive performance of dairy cows requires manipulation of estrus using estrus synchronization protocols. OBJECTIVES: The aim of this study was to evaluate the effect of reducing the length of estrus synchronization protocol by using two doses of prostaglandin injection on reproductive performance of Holstein dairy cows. METHODS: At first, all cows received GnRH (day 0), PGF2α on day 7, and GnRH on day 17. Then, cows assigned randomly to one of 3 groups: Group 1) PGF2α injection on days 22 and 23, estradiol benzoate injection on day 24. Group 2) PGF2α injection on days 23 and 24, estradiol benzoate injection on day 25. Group 3) Control group; injection of PGF2α on day 24, injection of estradiol benzoate on day 25. Estrus detection was performed twice a day up to 48 hours (AM/PM) using signs of estrus and fixed time AI protocol was used after 48 hours (if not previously inseminated). RESULTS: Conception rate in group 2 were significantly higher than control group (P≤
The EAZI-BREED CIDR is commonly used in estrous synchronization protocols for both beef heifers and cows. The label calls for insertion of a progesterone-impregnated controlled internal drug release (CIDR) for 7 consecutive days with an injection of prostaglandin F2α given a day before CIDR removal. Animals should display estrus 1 to 3 days after CIDR removal. Modifications to this protocol include administration of gonadotropin-releasing hormone (GnRH) at the time of CIDR insertion and administration of the prostaglandin injection at the time of CIDR removal on day 7. Use of GnRH in conjunction with a CIDR may improve estrous synchronization in beef cows and fertility at fixed-time insemination but may not be necessary when synchronizing beef heifers. Our objective was to compare heat response and fertility in heifers with or without GnRH administration at the time of CIDR insertion. Our hypothesis was that heifer fertility would be similar between treatments ...

In second experiment, a total of 114 lactating Bangladeshi Indigenous buffalo cows were used to study the efficiency of Ovsynch protocol for oestrous and fertility after AI with frozen semen of Italian Mediterranean buffaloes. The effect of some factors such as follicles and corpus luteum numbers, postpartum period on the fertility of synchronized Bangladeshi water buffaloes was also studied. Buffaloes were selected from two different areas in Bangladesh and were divided into three groups. Buffaloes of each group were subdivided as AM and PM according to time of administration of hormones of synchronization protocols. Among three groups, higher pregnancy rate (78% in AM) was observed in buffaloes of Group-3 where Ovsynch protocol was combined with a third GnRH injection at the time of AI. Similar to first experiment, we observed higher pregnancy rate (74 %) in buffaloes received induction treatment and insemination at AM time than that of PM counterpart (63%). Regarding the post-partum days, ...

132 male partners were normozoospermic with count , 20X106 sperm per ml, ,50% motile with forward progression (categories a and b) within 60 min of ejaculation and , 60% morphologically normal spermatozoa (WHO criteria) [7]. Male partners with sperm count ranging from 10X106 to 20X106 were asked to produce a second semen sample within 2 hours of the first sample on the day of insemination. Sixty-eight males having sub fertility as per WHO criteria did consent to the study. However 04 could not produce a second sample at the time of IUI, and 1 patient had total sperm immotility and was excluded from the study. A fresh ejaculate was delivered in a sterile 60 ml jar by masturbation on the day of insemination. Neat semen was left at room temperature for liquefaction for 30 minutes.The liquefied semen samples were analyzed for density and motility using a fixed-depth counting chamber (Makler). The liquefied ejaculate was transferred to a labeled sterile 14 ml round-bottomed disposable centrifuge tube ...
Genetic improvement of farm animals is a prime concern over the years for researchers. Several reproductive technologies have been employed to achieve this. Assisted reproductive technologies like Artificial insemination, Superovulation, In vitro Fertilization, Embryo Transfer have been introduced to overcome reproductive problems, to increase the offspring from selected females and to reduce the generation intervals in farm animals. The progress achieved during the last few years in the assisted reproductive technologies field has been phenomenal. Artificial Insemination (AI) is the most effective method being used for the genetic improvement of animals. Reproductive capacity and efficiency has been improved tremendously since the introduction of artificial insemination. The development of cloning using various cells from the animal body has created opening of a fascinating scientific arena. These technologies have been propounded as saviors of indigenous livestock breeds. These alternative ...
An insemination procedure uses a thin, flexible tube (catheter) to put sperm into the womans reproductive tract. For some couples with infertility problems, insemination can improve the chances of pregnancy.. Donor sperm are used if the male partner is sterile, has an extremely low sperm count, or carries a risk of genetic disease. A woman planning to conceive without a male partner can also use donor sperm.. Prior to insemination, the sperm usually are washed and concentrated (placing unwashed sperm directly into the uterus can cause severe cramps). Concentration is accomplished by selectively choosing highly active, healthy sperm that are more capable of fertilizing an egg.. ...

The GnRH-induced ovulation of small dominant follicles was associated with reduced pregnancy rates and late embryonic/fetal survival around the time of embryo-uterine attachment. PAGs are secreted by binucleated trophoblast cells into the maternal circulation and have been used to monitor placental function and embryo/fetal mortality. The overall objective was to examine the relationship between ovulatory follicle size and circulating concentrations of bPAG. Postpartum cows were treated with the CO-Synch protocol and timed artificial insemination and classified into one of four groups based on the size of the follicle induced to ovulate at GnRH-2. There was an effect of treatment on pregnancy rates at d 30 post insemination with pregnancy rate being higher following GnRH-induced ovulation of 14 to 15 mm compared to 12 to 13 mm follicles. The first increase in bPAG occurred on d 24. There was an effect of day on bPAG but no effect of ovulatory follicle size or ovulatory follicle size by day ...
Repeat breeders cause substantial loss in dairy herds mainly affecting the reproductive efficiency and economy of milk production in cattle and buffaloes. A study was conducted in cattle farms of various farmers of three districts of Central Region of Nepal; Kathmandu, Bhaktapur and Lalitpur during March-August 2016. A total of 20 repeat breeder cows were selected for the trial. Repeat breeder cows were identified based on the history of at least three repeated breeding at an interval of around three weeks. We applied Ovsynch protocol where two reproductive hormones; Gonadotropin Releasing Hormone (GnRH) and Prostaglandin (PGF2α) were injected. Pregnancy was initially diagnosed by Biopryn Test kit using serum samples. Rectal examination confirmed pregnancy after 2 months of artificial insemination (AI). 16 cows expressed clear estrus signs during fixed time AI. 5 (83.3%) out of 6 cows with cystic ovary expressed estrus at the time of fixed time AI. 4 (66.7%) of these cows became ...

Motile sperm are separated from dead sperm and other cells through the use of viscous solution. We will ask that the male partner bring or produce his specimen for our laboratory several hours prior to the IUI procedure.. Approximately 2 hours are required to process the sperm. After preparation, the sperm concentrate is placed through the cervix into the uterus by using a thin, flexible catheter. The time required for insemination is appx. 5-10 minutes. The patient may experience mild cramping during the procedure but this symptom should resolve shortly after the procedure is completed. It is not necessary to remain on the examination table after the procedure and it is possible to immediately resume usual activities. There is a small risk of infection following this procedure (,1%).. We require that all women interested in IUI treatment have blood testing of ovarian reserve (i.e. day 3 FSH and estradiol levels) regardless of her age. Also, as mentioned above, a hystero - salpingogram should be ...

Embryo Transfer Technology (ETT) plays an important role in improving productivity of dairy cattle ( Bos indicus ). Embryo Transfer Technology allows top quality female livestock to improve a herd or flock in much the same way that artificial insemination has allowed greater use of superior sires. The technology hastens genetic enhancement by virtue of its capacity to reduce generation interval and is also useful in progeny testing programmes. A retrospective study analysed conception rates data collected over a period of six years, from 2007 to 2012. A total of 115 embryos had been transferred during that period. The factors affecting conception rates (CR) included embryo developmental stage, deposit site and stage of recipient in days after estrus. The deposit site had a significant effect on CR (χ 2 =0.27395; p<0.05). The quality and stage of the embryo development influenced the CR. Generally, CR reduced as the growth of the embryo. Days after estrus also significantly affected the CR, whereby

The lateral flow test (LFT) is an immunochromatographic method that utilises an immunostrip for non-laboratory diagnostic purposes. The present study evaluated a milk progesterone LFT against the enzyme immunoassay (EIA) to confirm oestrus and a non-pregnancy diagnosis. In total, 277 milk samples from 70 cows were analysed, collected on the day of artificial insemination and at 19 days, 21 days and 24 days post insemination. The level of accuracy of the LFT compared with the EIA was 95.0 per cent for milk samples containing ,2 ng/ml progesterone and 97.0 per cent for milk samples containing ,10 ng/ml progesterone. The validation of oestrus by the LFT was 98.6 per cent accurate using 2 ng/ml progesterone as the EIA estimate for oestrus. The test performance for a non-pregnancy diagnosis was subject to the day of milk sampling, showing the highest accuracy on day 24 post insemination for both tests. When optimised for maximum specificity, and compared with rectal palpation, the LFT had a ...
There are several fertility treatment options available, thanks to modern medicine. But which one to choose could be a tough decision. The top fertility doctor in Glendale at Pacific Reproductive Center shares the top signs that you should choose in vitro fertilization or IVF as your fertility treatment. Tubal blockage. A hysterosalpingogram (HSG) can reveal tubal blockage. Blocked fallopian tubes are unable to let the ovum and the sperm fertilize making fertilization impossible. IVF is the treatment of choice for women with blocked fallopian tubes, says the leading fertility doctor in Irvine.. Male factor infertility. Patients with less than 10 million total motile sperm are advised to consider IVF.Semen analysis is done to assess sperm quality and quantity.. History of failed insemination cycles. If there is a history of repeated failed intrauterine insemination (IUI) cycles, IVF is recommended by the best fertility doctor in Glendale at Pacific Reproductive Center.

Optimizing CL regression in specific groups of cows may be particularly challenging; hence, new alternatives should be explored to increase CL regression during the TAI protocols. The current study is the first to show the effect of administrating the luteolytic dose of PG in two injections on days 5 and 6 of the TAI protocol after of estrus expression comparing to the Cosynch protocol in a large dairy herd. This is the first study to demonstrate that the two PG injections can increase P/AI in different seasons without any P4 supplementation.. As in the previous study (Alnimer and Ababneh, 2014), the interval between the PG injection and the start of the treatment was an approach that simulated Presynch 14 protocol with one less PG injection and increased stage synchronization at the beginning of the protocols (Moreira et al., 2001; Vasconcelos et al., 1999). However, the interval from the setup injection of PG on Day 30 pp to the detection of estrus in the EPG-PG and ECO-72 groups complicated ...

Testosterone cypionate is an oil based testosterone product which will result in a rise of testosterone concentrations for several days after administration, followed by elevated levels for approximately two weeks. Popular with our friends over the other side of the pond, cypionate is a favoured choice among American athletes who claim the ester brings about a better result the that of the enanthate ester. Truth is, testosterone cypionate is very similar to that of the testosterone enanthate apart from the enanthate being one carbon atom lighter, which will bring about unnoticeable differences to the end user. The enanthate may contain slightly more testosterone due to the ester being included in the total milligram weight, but this amount will be minimal and not worth being concerned about. So out of the choice of the two products, choose the one in which you can get cheapest and pharma grade.. We can supply high quality injectable steroids as below ...
