Throughout biology, cells and organisms use flagella and cilia to propel fluid and achieve motility. The beating of these organelles, and the corresponding ability to sense, respond to and modulate this beat is central to many processes in health and disease. While the mechanics of flagellum-fluid interaction has been the subject of extensive mathematical studies, these models have been restricted to being geometrically linear or weakly nonlinear, despite the high curvatures observed physiologically. We study the effect of geometrical nonlinearity, focusing on the spermatozoon flagellum. For a wide range of physiologically relevant parameters, the nonlinear model predicts that flagellar compression by the internal forces initiates an effective buckling behaviour, leading to a symmetry-breaking bifurcation that causes profound and complicated changes in the waveform and swimming trajectory, as well as the breakdown of the linear theory. The emergent waveform also induces curved swimming in an ...

The aim of this study was to examine whether the secreted fluid from the uterus influences the survival and fertilization capacity of fowl sperm in the hen oviduct. Hens with either regular uterine fluid secretion or irregular uterine fluid secretion were artificially inseminated through the transfer of sperm into the uterus. Twenty-four hours after artificial insemination, 3 hens with regular uterine fluid secretion and 3 hens with irregular uterine fluid secretion were killed and the utero-vaginal junction and infundibular sperm storage tubules were observed for the presence of sperm. There was no difference (P|0.05) in the fill rate of either the utero-vaginal junction sperm storage tubules or the infundibular sperm storage tubules between hens with regular or irregular uterine fluid secretion. However, the sperm transferred into hens with regular uterine fluid secretion had a longer lifespan and fertilization ability than the counterpart group (Psecretion from the hen uterus may sustain the

Our observations constitute the first description of the functional morphology of penile eversion and ejaculation in birds. Eversion of the penis is explosive, occurring in approximately a third of a second in air, and less than half a second inside glass barriers. It is difficult to predict whether eversion inside of the female is faster or slower, because we do not know enough about how the female oviduct functions during intromission and the interactions between the male and female genitalia (see below). The explosive nature of penis eversion and ejaculation in waterfowl provides males with a mechanism to forcefully achieve insemination in a short period of time. Previous description of eversion in 15-20 s described by Liebe (1914) (cited in King 1981) is inaccurate and artifactual.. Our observations document that the s. spermaticus forms an efficient channel for sperm transport. Semen is ejected from the tip of the penis at a speed of up to 1.6 m s−1. Ejaculation is exactly timed relative ...
Adenomyosis is a benign condition characterized by the presence of endometrial glands and stroma deep within the myometrium. In recent years, the potential negative impact of adenomyosis on in vitro fertilization clinical outcomes has gained momentum, as well as, the possible link of this condition with obstetrical complications. The aim of this narrative review is to elucidate the possible association between uterine adenomyosis, infertility, and poor obstetrical outcomes. Several theories have been proposed to clarify the potential harmful impact of adenomyosis on fertility, such as a functional and structural defect of both the eutopic endometrium and the inner myometrium, an impairment of the uterine system of sperm transport, the presence of uterine dysperistalsis and of high levels of free radicals in the uterine milieu of women with the disease ...

Internal fertilization occurs in birds and eutherian mammals. Foetal development, however, is either extra- respectively intra-corpore (egg vs uterus). In these animal classes, the female genital tract stores ejaculated spermatozoa into a restricted oviductal segment; the functional pre-ovulatory sperm reservoir, where they survive until ovulation/s occur. Paradoxically, this immunologically foreign sperm suspension in seminal fluid/plasma, often microbiologically contaminated, ought to be promptly eliminated by the female local immune defence which, instead, tolerates its presence. The female immune tolerance is presumably signalled via a biochemical interplay of spermatozoa, as well as the peptides and proteins of the extracellular seminal fluid, with female epithelial and immune cells. Such interplay can result in gene expression shifts in the sperm reservoir in relation to variations in fertility. To further aid our understanding of the underlying mechanisms, this thesis studied the proteome ...
It will be around five days (approximately) before your period that youll notice the biggest of changes in your cervical mucus, and this is when you will produce the most. Especially the cervical fluid as it shows up before ovulation and will give a couple a chance to abstain until after ovulation. Well, its true there is an increase In CM before you find out got are pregnant. Read reports about cancer symptoms by our users with Cervical Cancer, which involve terms such as abnormal, back, bleeding, discharge, fatigue, heavy, intercourse, irregular, pain, pap, pelvic, periods, sex, time, vaginal. To sum it up, CM (cervical mucus) is one of the best ways to gauge where you are in your menstrual cycle (one cycle is the time from the start of one period to the start of the next one, roughly a month) and changes based on estrogen levels. If you are seeing a cottage discharge then it can indicate a yeast infection. If there isnt enough or its too thick, the sperm will get "beached" and never make ...

This bundle helps ensure proper nutrition, hormonal balance, and cervical mucus production which all play important roles in the conception process.
Structural and functional evidence indicate that the fucose-binding lectin present on bull sperm is a seminal plasma protein secreted by the seminal vesicles called PDC-109 (BSP-A1/A2) (Gwathmey et al 2003, Ignotz et al 2001). Upon ejaculation, this protein associates with the sperms plasmatic membrane enabling it to bind to the oviductal epithelium (figure 1). This proposed mechanism explains the limited binding capacity of sperm that have not been in contact with seminal fluids i.e., epididimal sperm (Gwathmey et al 2003, Petrunkina et al 2001). Furthermore, excess PDC-109 in seminal plasma may block sperm binding sites on posterior portions of the female reproductive tract facilitating sperm transport to the oviducts (Suárez, 2002). Mucus secretions. Overstreet and Cooper (1975) first observed that rabbit sperm collected from the isthmus of does before ovulation were immotile or weakly motile. This observation is interpreted as a transitory inhibition or suppression of sperm flagellar ...
Male infertility refers to a condition where a male is unable to impregnate a fertile female. Male infertility is caused due to deficiencies in his semen. A mans fertility depends on both the quality and quantity of his sperm. The total number of sperm a man ejaculates is important as a low sperm count is one of the major reasons that accounts for him failing to initiate a pregnancy.. Other major causes of male infertility include the failure of the testes to make sperm, sperm transport problems, and low levels of hormones made in the pituitary gland. IVF is a remedy for male infertility as it provides a platform for intra-cytoplasmic sperm injection, a laboratory technique procedure that is used in the treatment of various infertility problems. This technique enhances the fertilization phase by injecting a single sperm into a mature egg and has proven to be extremely effective in allowing a female to conceive after insertion into the uterus.. ...
Vas-occlusive contraception is a form of male contraception that blocks sperm transport in the vas deferens, the tubes that carry sperm from the epididymis to the ejaculatory ducts. Various vas-occlusive contraceptive methods have been researched for human-use, with interest in both reversible and irreversible methods, with the purpose of finding a suitable alternative to vasectomy and possible hormonal contraceptive treatments that are currently being researched. Potential methods include clips, plugs, valves, and other devices. There are numerous vas-occlusive contraceptive methods and devices that have been researched. Outlined here are a few main categories and descriptions. An intravasal control valve is a reversible valve implanted in the vas deferens with the ability to either inhibit or permit sperm passage depending on the position of the device. Bionyx has developed a T-shaped intravasal control valve composed of gold and stainless steel for use in humans. Through rotation, a ...
In boars, sperm cohorts are sequentially emitted in epididymal cauda fluid and resuspended in different Mixtures of accessory sex gland secretions while ejaculated in various fractions. During natural mating, these ejaculate fractions sequentially enter the cervix-uterine lumen, are quickly transported towards the tips of the uterine horns and colonize the oviductal sperm reservoirs (SR). Using a simple experiment, we tested the hypothesis that the first ejaculated sperm subpopulation (fortuitously present in the peak portion of the sperm-rich fraction [SRF], the so-called Portion 1, P1) is, by reaching first the SR, overrepresented there. Spermatozoa from P1- and of P2- (last portion of the SRF and the Post-SRF) were collected from 3 fertile boars. PI-spermatozoa were fluorophore DNA-stained, while P2-spermatozoa were kept unstained. Weaned estrous sows were conventionally inseminated (12 h after onset of estrus) with similar sperm numbers (approx 10(.) x 10(9) spermatozoa) per portion but in ...
Youngs syndrome, also known as azoospermia sinopulmonary infections, sinusitis-infertility syndrome and Barry-Perkins-Young syndrome, is a rare condition that encompasses a combination of syndromes such as bronchiectasis, rhinosinusitis and reduced fertility. In individuals with this syndrome, the functioning of the lungs is usually normal but the mucus is abnormally viscous. The reduced fertility (azoospermia) is due to functional obstruction of sperm transport down the genital tract at the epididymis where the sperms are found in viscous, lipid-rich fluid. The syndrome was named after Donald Young, the urologist who first made observations of the clinical signs of the syndrome in 1972. There have been several studies undertaken suggesting that contact with mercury might cause the syndrome. A variant of Youngs syndrome has been observed in an individual, showing slightly different signs and symptoms.

Cervical mucus has a very important role in the conception phase. It is vital that you improve the quantity of your cervical mucus as it aids the sperm in its journey to locate the egg. Therefore, the mucus must be prevalent enough to keep the sperm flowing in the direction of the egg.. One way to improve your cervical mucus quantity is to cut back on certain substances. Items such as caffeine and tobacco will hinder the production of cervical mucus and make it more difficult for the sperm to reach the egg. Eliminating or decreasing the intake of these items will help the process greatly.. Another way to improve your cervical mucus quantity is to drink enough fluids each day. Water is the best type of fluid to drink and you should drink approximately 10-6 oz. glasses of water per day. Besides drinking water each day, you should also drink grapefruit juice. The components of the grapefruit juice will aid in helping to produce extra cervical mucus which will in turn help you in your conception ...
CORTES, Manuel E.; GONZALEZ, Fernando and VIGIL, Pilar. Crystallization of Bovine Cervical Mucus at Oestrus: An Update. Rev. Med. Vet. [online]. 2014, n.28, pp.103-116. ISSN 0122-9354.. Bovine cervical mucus changes its biochemical composition and biophysical properties due to the variations in sex steroid levels during the oestrous cycle. As a consequence of oestrogen rise, cervical mucus is produced in larger amounts at oestrus-a stage also characterized by an increase in mucus crystallization when observed under light microscopy. The objective of this article is to provide an updated review of the main aspects regarding crystallization of bovine cervical mucus. First, it makes reference to the composition of cervical mucus and the critical functions that this secretion exerts on bovine reproductive physiology, as well as in other species. Then, the article deals with the phenomenon of crystallization observed in cervical mucus, describing the main models used to classify the crystalline ...

This method depends on the observation of changes in the consistency and the volume of cervical mucus in relation to the ovulation. On feeling the cervical mucus in the vagina by fingers the dry days and the wet days are recognized by the women. The wet days are the fertile days.. The number of wet days are about 10 days in 28 day cycle. Wet days start with sticky white mucus for 2-3 days following 2-3 days dry days after menses. Sticky white mucus days is followed by clear slippery profuse mucus for 3-5 days (this slippery mucus is capable of being stretched between two fingers) . The last day is called the peak day. Following peak day there is sticky mucus for 3 days. This the end of fertile period.. Many women are unable to observe these symptoms and thus the Pregnancy failure rate is as high as 22 per 100 women year.. ...

So I always believed you had CM (cervical mucus) discharge like during ovulation. My predicted day of ovulation by calendar was the day before yesterday (we BD (baby dance (sex)) 2 days before and day of.) this morning I had sticky cm. I was thinking maybe my ovulation Date was off, as I believed this was a sign of ovulation. I was talking to my friend and she said she thought that cm was after ovulation, but I couldnt sworn it was during? Like a sign of impending? What do you guys go by? I cant seen to find a straight answer online. Going to BD (baby dance (sex)) today anyway just in case! Thank you all for your opinions/advice/knowledge!

Symptoms of the homeopathic remedy Silicea Terra from the Guiding Symptoms of our Materia Medica by Constantine Hering, a ten volumes comprehensive record of confirmed symptoms, published in 1879. It is very fertile and will help sperm reach the egg. Fertile cervical mucus develops as a co-efficient of the increase in the estrogen hormones during the first half of your menstrual cycle. Under the influence of estrogens, cervical mucus becomes abundant, clear, and stretchable, and somewhat like egg white. It contributes to fertilization. While egg white cervical mucus is the best for fertility, sperm are able to swim through clear and watery cervical mucus without much resistance. This "egg white" cervical mucus is the most fertile, as it allows sperm to swim easily into the cervix. What Is Cervical Mucus? A womans cervix has tiny glands that produce mucus every day. Gradually, as you approach ovulation, the cervical mucus will increase, though the consistency will be "sticky" and the color will ...

I keep talking about cervical mucus, so I want to make sure that its clear what Im referring to.. Cervical mucus is a type of fluid that your body makes when you are fertile (close to ovulation). This is a magical fluid because it allows sperm to live up to five whole days inside the womans reproductive tract. This is why its so important to know what it is and how to interpret it, because knowing this will allow you to know when you can (or cannot) get pregnant in each menstrual cycle.. The vagina is a naturally wet environment, and youll usually have some kind of dampness or moisture down there (called vaginal cell slough), so thats not what Im talking about.. Mucus is what is often referred to as discharge and the key difference is that it has staying power. What I mean is that you can pick it up and play with it between your fingers and it wont go anywhere. You can stretchy out multiple times and it wont go anywhere. This is in contrast to the normal cell slough that may be damp or ...
