Adenovirus-mediated gene delivery and in vitro microinsemination produce offspring from infertile male mice. (1/84)

Sertoli cells play a pivotal role in spermatogenesis through their interactions with germ cells. To set up a strategy for treating male infertility caused by Sertoli cell dysfunction, we developed a Sertoli cell gene transfer system by using an adenovirus vector, which maintained long-term transgene expression in the testes of infertile mice. Introduction of an adenovirus carrying the mouse Steel (Sl) gene into Sertoli cells restored partial spermatogenesis in infertile Steel/Steel(dickie) (Sl/Sl(d)) mutant mouse testes. Although these males remained infertile, round spermatids and spermatozoa from the testes produced normal fertile offspring after intracytoplasmic injection into oocytes. None of the offspring showed evidence of germ line transmission of adenoviral DNA. Thus, we demonstrate a successful treatment for infertility by using a gene therapy vector. Therefore, adenovirus-mediated gene delivery into Sertoli cells not only provides an efficient and convenient means for studying germ cell-Sertoli cell interactions through manipulation of the germ cell microenvironment in vivo, but also is a useful method to treat male infertility resulting from a Sertoli cell defect.  (+info)

Restoration of spermatogenesis by lentiviral gene transfer: offspring from infertile mice. (2/84)

Disruption of spermatogenesis found in azoospermia and oligozoospermia is thought to be of primarily genetic origin. Sl/Sl(d) mutant mice offer a model system in which lack of transmembrane type c-kit ligand (KL2) expression on the somatic Sertoli cell surface results in disruption of spermatogenesis. We investigated the ability of adeno-, adeno-associated-, retro-, and lentiviral vectors to transduce Sertoli cells and found that transduction with either adeno- or lentiviral vectors led to reporter gene expression for more than 2 mo after testicular tubule injection. Because adenoviral vectors showed toxicity, lentiviral vectors were used to express the c-kit ligand in Sl/Sl(d) Sertoli cells. Restoration of spermatogenesis was observed in all recipient testes. Furthermore, the sperm collected from recipient testes were able to generate normal pups after intracytoplasmic sperm injection. None of the offspring carried the transgene, suggesting the inability of lentiviral vectors to infect spermatogenic cells in vivo. We propose that lentiviral vectors can be used for gene therapy of male infertility without the risk of germ-line transmission.  (+info)

Male phenotype predicts insemination success in guppies. (3/84)

Theory predicts that mate choice can lead to an increase in female fecundity if the secondary sexual traits used by females to assess male quality covary with the number of sperm transferred during copulation. Where females mate multiply, such a relationship between male attractiveness and ejaculate size may, additionally (or alternatively), serve to augment the effect of indirect selection by biasing paternity in favour of preferred males. In either case, a positive correlation between male attractiveness and the size of ejaculates delivered at copulation is predicted. To date, some of the most convincing (indirect) evidence for this prediction comes from the guppy, a species of fish exhibiting a resource-free mating system in which attractive males tend to have larger sperm reserves. We show that, during solicited copulations, male guppies with preferred phenotypes actually transfer more sperm to females than their less-ornamented counterparts, irrespective of the size of their initial sperm stores. Our results also reveal that, during coercive copulations, the relationship between ejaculate size and the male's phenotype breaks down. This latter result, in conjunction with our finding that mating speed--a factor under the female's control-is a significant predictor of ejaculate size, leads us to speculate that females may exert at least partial control over the number of sperm inseminated during cooperative matings.  (+info)

Frequency of multiple inseminations in field-collected Anopheles gambiae females revealed by DNA analysis of transferred sperm. (4/84)

We investigated the frequencies of single and multiple matings in field-collected female Anopheles gambiae by conducting microsatellite DNA analyses on the sperm contained within their spermatheca. Amplifcation by a polymerase chain reaction (PCR) at four loci allowed the detection of sperm extracts exhibiting more than two alleles per locus, thereby revealing the occurrence of multiple inseminations. Polyandry was found in six of 239 females examined, or 2.5% of the samples. Previous analyses of the molecular form of the sperm and female extracts using a PCR-based diagnostic procedure showed that two of these multiple inseminations involved cross-mating between two chromosomal/molecular forms of An. gambiae s.s. Thus polyandry occurred within-form in 1.7% of examined females while other multiple inseminations may be linked to processes of reproductive isolation between forms of An. gambiae.  (+info)

Repeated inseminations required for natural fertility in a wild bird population. (5/84)

In most bird species, pairs copulate many times before egg laying. The exact function of repeated inseminations (i.e. successful copulations) is unknown, but several suggestions have been made. We tested the hypothesis that repeated inseminations are required to ensure fertilization of eggs, by using an experimental method where free-ranging male collared flycatchers (Ficedula albicollis) were prevented from inseminating their mates. We show that egg fertility was lower when females had not copulated during the studied part of their fertile period. By counting sperm on the inner perivitelline layer of eggs, we estimated that a minimum of 86 sperm must reach the site of fertilization to ensure average fertility. Using the timing of inseminations and the numbers of sperm on successive eggs, we show that repeated copulations are necessary to achieve an average rate of fertilization of a single clutch. Our results thus provide evidence that repeated inseminations function to ensure fertilization success. We discuss possible constraints on sperm production and utilization that may have contributed to this pattern.  (+info)

Japanese quail (Coturnix japonica) inseminations are more likely to fertilize eggs in a context predicting mating opportunities. (6/84)

Theoretical developments in behavioural ecology have generated increased interest in the proximate mechanisms underlying fertilization, but little is known about how fertilization success is regulated by cues from the external or social environment in males and females. Here, we use a Pavlovian conditioning paradigm to show that inseminations resulting from mating male and female Japanese quail (Coturnix japonica) are more likely to fertilize eggs when they occur in a context predicting that an opposite-sex bird will appear than when they occur in a context predicting that an opposite-sex bird will not appear. This effect occurs when either the male or the female is the target of the conditioning. Thus, processes occurring during or after mating that contribute to fertilization success are subject to the influence of distal cues, confirming control by brain-level mechanisms. Conditioning is a widespread property of the nervous system and the demonstration that context conditioning can influence male and female reproductive success, and not simply mating success, has widespread implications for the fertilization successes of different types of copulation in natural mating systems.  (+info)

Estimation of second polar body retention rate after conventional insemination and intracytoplasmic sperm injection: in vitro observations from more than 5000 human oocytes. (7/84)

PURPOSE: Tripronucleate (3pn) development after conventional insemination (CONV) or ICSI was analyzed to estimate the rate of second polar body retention giving rise to 3pn formation. METHODS: Data from 453 consecutive IVF cycles were reviewed during a 6-month period. Mature oocytes were monitored in ICSI (n = 3195) and CONV (n = 2274) groups by fertilization assessment 16-18 h post-insemination. Ovulation induction protocols and in vitro culture conditions remained constant during the study interval. RESULTS: Normal (2pn) fertilization occurred in 74.2% and 70.5% for CONV and ICSI groups, respectively (p < 0.003). 1pn formation was observed in 4.5% of CONV oocytes, and 2.5% of ICSI oocytes (p < 0.001); 3pn formation was 8.1% in the CONV group, and 2.5% in the ICSI group (p < 0.0001). We observed 4pn formation in 0.4% of oocytes in the CONV group, but in only 0.04% of oocytes fertilized with ICSI (p < 0.007). Cellular degeneration occurred in 2.4% of oocytes inseminated conventionally, and in 3.5% of oocytes fertilized by ICSI (p = 0.02). Maternal age did not impact pronuclear status. CONCLUSIONS: We found the 3pn formation rate after ICSI to be approximately one-third that observed in the CONV group. Extrapolating the ICSI data to the CONV data, it may be inferred that 2.5% of 3pn development after CONV was due to second polar body retention. This suggests that 5.6% of CONV oocytes showed dispermic fertilization. Decreasing oocyte quality with increasing maternal age had no apparent influence on any of the fertilization outcomes.  (+info)

Sperm-induced modification of the oviductal gene expression profile after natural insemination in mice. (8/84)

In mammals, the physiological interaction between spermatozoa and oviductal epithelia involves intimate and specific contact between the two cell types. Spermatozoa may undergo stringent selection processes within the female reproductive tract before they meet and fertilize oocytes. The physiological basis of the sperm selection process is largely unknown. Here we tested the hypothesis that the oviduct has a recognition system for spermatozoa that can detect the arrival of spermatozoa in the oviduct after insemination, resulting in alterations of the oviductal transcriptome. We initially performed a global screening of the oviductal transcriptome in mice 1) at the time of estrus (mating) and 2) 6 h after mating. Transcriptional alterations in the oviduct after mating were attributed to the presence of spermatozoa in the oviduct after mating and also to changes in the hormonal environment as female mice underwent the transition from estrus to diestrus. To distinguish these possibilities, female mice were then mated with T145H mutant mice, which because of spermatogenic arrest, produce seminal plasma but no spermatozoa. Focusing on two molecules that in the first experiment were upregulated after mating, it was found that adrenomedullin and prostaglandin endoperoxidase synthase 2 transcripts were upregulated in the oviducts of mice only after mating with fertile males; those mated with T145H infertile males showed significantly less response. These results indicate that it is the arrival of spermatozoa in the oviduct that activates one or more signal transduction pathways and leads to changes in the oviductal transcriptome profiles.  (+info)

As drastic and nasty as it seems, traumatic insemination does provide males with several distinct advantages they wouldnt otherwise get.

LETROZOLE THERAPY Limited Benefit of Extended Letrozole Therapy BY CATLIN NALLEY ata from the NSABP B-42 (NRG Oncology) trial was pre-sented at the 2016 San Antonio Best Cancer Symposium that determined an additional 5 years of hormone ther-apy with letrozole following an initial 5 years of aro-matase inhibitor-based adjuvant hormone therapy did not result in statistically signifi cant improvement in disease-free survival (DFS) or overall survival (OS) in postmenopausal women with early-stage hor-mone receptor (HR)-positive breast cancer. In this randomized, double-blinded, placebo-controlled trial, we found that, while extended letrozole therapy demonstrated a trend toward improved disease-free survival, the difference was not statisti-cally signifi cant, Terry Mamounas, MD, MPH, Medical Director of the Comprehensive Breast Program at UF Health Cancer Center at Orlando Health and Chair of the NRG Oncology Breast Committee, explained in a press release. Overall survival benefi t with ...
Updated results from the NSABP B-42 trial, presented at the San Antonio Breast Cancer Symposium (SABCS) this week, showed that giving 5 years of the aromatase inhibitor letrozole after 5 years of prior hormonal therapy resulted in a higher rate of disease-free survival in postmenopausal women.Background
The most studied nucleation status is multinucleation, which is defined as the presence of more than one nucleus in at least one blastomere of the embryo (Jackson et al., 1998; Van Royen et al., 2003). Multinucleation can be evaluated both in the early cleaved Day 1 (26-28±1 h post-insemination), Day 2 (44 ± 1 h post-insemination) and Day 3 (68 ± 1 h post-insemination) cleavage stage embryos, although the assessment of a Day 3 embryo may be more complicated due to the smaller cell size and the larger number of cells (Van Royen et al., 2003). Embryo quality has been shown to correlate with multinucleation, and 4-cell embryos on Day 2 and 8-cell embryos on Day 3 show reduced multinucleation compared with the other cell stages observed on these days (Van Royen et al., 2003; Ziebe et al., 2003).. Multinucleation is predictive of a decreased implantation potential (Jackson et al., 1998; Pelinck et al., 1998; Van Royen et al., 2003; Moriwaki et al., 2004) and multinucleated embryos are associated ...
When we refer to online fertility services, we usually speak about sperm donation. This is because egg donation requires a minor surgical intervention to obtain and implant the eggs, and so requires a medical clinic to perform it. Sperm, on the other hand, can be more easily obtained.. There are principally two ways in which a woman can conceive with donated sperm. The first is called artificial insemination (AI for short), and it usually involves the woman using a self-insemination device at home. This can also be done in the clinic context as well. The second method is referred to as natural insemination (NI), which is intercourse timed to coincide with ovulation, with the express purpose of conception.. People are attracted to using these services for a number of reasons. It could be that they are unable to conceive with their current partner, either because of fertility problems, or because they are in a same-sex relationship. They may also want to have a child, but havent found a partner ...

The Price is Right - What Makes Pomeranians so Expensive Nowadays?. True, this is a relatively painful aspect with regard to this particular breed. Prices in Israel nowadays are sky-high and it is not always clear whether they are justified.. Actually, breeders prefer to sell dogs at lower prices since that enables them to find homes for more of their puppies. The high prices are derived from the various expenses involved in breeding healthy dogs.. First of all, when a breeder sets out to buy a new dog for his kennel he is required to pay a hefty price. Good breeders usually try to buy top-quality dogs from the worlds leading breeders. Famous breeders tend to ask higher prices for their dogs.. Secondly, Pomeranians do not conceive easily and often require artificial insemination, a procedure that is both costly and does not ensure results (although natural insemination does not ensure results either).. Thirdly, sometimes whelping itself is not natural and a C-section is required to remove the ...

Introduction/Aim: Adjuvant treatment with aromatase inhibitors (AI) is associated with accelerated bone loss and increase in lipid levels. The effectiveness and tolerance of extended treatment with AI beyond 5 years is currently under investigation. In the SOLE study, five years of continuous (C) extended letrozole is compared to interrupted therapy (9 months on, 3 months off letrozole) after 5 yrs of tamoxifen, AI or sequential hormonal therapy. We have evaluated the bone mineral density and lipid levels during the extended use of letrozole beyond 5 yrs in a cohort of patients included in the SOLE study.. Patients and methods: Postmenopauzal women with HR+ BC, receiving extended continuous (C) or intermittent (I) letrozole for 5 yrs after 5 yrs of tamoxifen, 5 yrs of an AI, or switch therapy within the first 5 years, were included. Bone mineral density was measured at the lumbar spine (L2-4) and total hip BMD (g/cm2), by dual energy X-ray absorptiometry (DXA). The mean percentage change in BMD ...

Seth. You brilliantly spoke to so much of what I feel. Im also gay, in DC, and newly married to my husband by my congregation (Quaker). What I remember in our clearness counseling before our marriage was approved was being admonished (in that very gentle Quakerly way) that if there was anything wrong in our marriage, that we would seek help of the congregation because every gay couple up to that point who had been married had wound up getting a divorce. I was even told of a gay couple, who had been together for 27 years, had asked for and received the congregations blessing to be married, had gone ahead and gotten married and then split up within 2 years. It made me nervous to hear that, but now - I just cannot conceive of life without my husband.. Being in DC, with a big gay community, a lot of us slept around (to put it politely), and that at least among gay men, a lot of them continue to do so, until sometime in mid-to-late 40s when you are no longer physically perfect and it becomes ...
Third, things have changed very rapidly (this is the main point of Andrew Gelmans post). When I was in graduate school (2000-2005), I dont remember hearing concerns about replication and standard operating procedures included lots of stuff that I would now consider garden of forking paths/p-hacking. 2011 was a major turning point: Daryl Bem reported his evidence of ESP (side note: he was working on that since at least the mid-to-late 90s when I was undergrad at Cornell and heard him speak about it). At the time, the flaws in that paper were not at all clear. That was also the year a paper called False-positive psychology was published (in Psychological Science), which showed that researcher degrees of freedom (or p-hacking) make actual false positive rates much higher than the nominal p , 0.05 values. The year after that, in 2012, Greg Franciss paper (Too good to be true) came out showing that multi-experiment papers reporting consistent replications of small effect sizes are ...

The six patients have been notified and are being monitored; none ...
The gulf coast of Florida has diurnal tides; that is, one high and one low per day. Water depths are lowest in the morning and moderate to high in the mid-to-late afternoon. The tidal range at Pelican Bay is only about 2′. The rhumb line from the beach to the State Park docks will get down to 5-1/2′ at MLLW. By the time you get to the docks, youll see 6-1/2′ or more. There is a deep pool correctly charted on the current charts that carries 9′, which is the deepest water in the bay. Some older charts that are still widely circulated do not show that 9′ pool correctly. If you do not see that deep pool, you do not have the current charts of the basin.

So this morning after my seven days of silence on this blog, I wonder why? What have I left out? The fact is these were some of the most difficult seven days yet since I began treatment. Stuck inside this house for days on end, staring at the same walls, struggling to eat and drink, I mostly lounged on the couch in between times to nurse a bleeding hemorrhoid and make sure I was taking the right balance of laxatives and stool softeners. I had no energy for nor interest in the computer or checking email. I watched back-to-back episodes of The Peoples Court during the mid-to-late morning timeslots, only to find nothing at all I wanted to watch. So with a click on the remote, silence filled the room. No energy to get up, I continued to lay there and stare off in space, feel my frustration, wipe tears so I could check the clock and hope time was passing quickly so this day would be over and Id be one day closer to feeling better. I spent many hours doing jus ...

Gametogenesis : The gametogenesis is the formation of gametes i.e. sperm in males and ovum in females. It is also known as spermatogenesis and Oogenesis.. Insemination: Insemination is the deliberate introduction of sperm into a female animal or plant for the purpose of impregnating or fertilizing the female for sexual reproduction. The sperm is introduced into the uterus of a mammal or the oviduct of an oviparous (egg-laying) animal.. Fertilisation: fusion of male and female gametes and it eventually lead to the formation of zygote.. Implantation: After the formation of blastocyst and its development. Blastocyst gets attached to the uterus wall. This process is called implantation.. Gestation: Gestation, in mammals, the time between conception and birth, during which the embryo or foetus is developing in the uterus..

The frequent wounding of female bedbugs (Cimex lectularius: Cimicidae) during copulation has been shown to decrease their fitness, but how females have responded to this cost in evolutionary terms is unclear. The evolution of a unique anatomical structure found in female bedbugs, the spermalege, into which the males intromittent organ passes during traumatic insemination, is a possible counteradaptation to harmful male traits. Several functions have been proposed for this organ, and we test two hypotheses related to its role in sexual conflict. We examine the hypotheses that the spermalege functions to (i) defend against pathogens introduced during traumatic insemination; and (ii) reduce the costs of wound healing during traumatic insemination. Our results support the defence against pathogens hypothesis, suggesting that the evolution of this unique cimicid organ resulted, at least partly, from selection to reduce the costs of mating-associated infection. We found no evidence that the ...

Traumatic insemination, also known as hypodermic insemination, is the mating practice in some species of invertebrates in which the male pierces the females abdomen with his penis and injects his sperm through the wound into her abdominal cavity (hemocoel).[1] The sperm diffuse through the females hemolymph, reaching the ovaries and resulting in fertilization. The process is detrimental to the females health. It creates an open wound which impairs the female until it heals, and is susceptible to infection. The injection of sperm and ejaculatory fluids into the hemocoel can also trigger an immune reaction in the female. Bedbugs, which reproduce solely by traumatic insemination, have evolved a pair of sperm-receptacles, known as the spermalege. The spermalege reduce the damage to the female bedbug during traumatic insemination. ...
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 ...

In order to reach fertilization in the context of IVF, the presence of high concentrations of spermatozoa is associated with a higher degree of sperm metabolism and a higher concentration of sperm degradation products, which may adversely affect not only sperm and oocyte viability and the fertilization rate. The effect of a high concentration of sperm used for oocyte insemination appears also to be negative on embryo development (Dumoulin et al 1992*). If that is true, lowering the sperm concentration for oocyte insemination might improve embryo quality and result in a higher implantation rate per embryo. Therefore, we tested the hypothesis that the percentage of 8 cell-embryos on day 3 after IVF is significantly higher (40%) after insemination with a low sperm concentration (150 000/ml spermatozoa) than after insemination with a higher sperm concentration (30%; group 600 000/ml spermatozoa ...
Outline. These notes are additional to the Registration Rules. They provide information for members who wish to use an Artificial Insemination (AI) service and detail how an insemination agent may register with the Society.. It will be considered a breach of the rules to submit a Mating Card when AI procedures have been used to achieve insemination of a bitch. These notes describe the use of an AI Form for such notification. Note: this does not encompass what may be described as an assisted mating. If someone undertakes the transfer of semen from dog to bitch, on the same day, then a normal Mating Card should be used accompanied by a brief statement of what occurred.. Summary. The sire and dam must be registered and comply with the Registration Rules.. If semen is to be obtained and supplied by an Agent, the Agent must agree to the terms of a detailed AI Protocol and make an annual registration as an Affiliated Member. The protocol requires secure identification of dogs and authorisations by ...

Factors which increase the efficiency of the AI technique could result in higher pregnancy rates and larger litter sizes. Although many items may not be clearly established, the factors of greatest importance after timing and semen fertility, must include volume and sperm numbers inseminated. The volume and the number of sperm delivered into the uterus depend upon the ease of fluid flow into the female tract. Often, females are stimulated and actually suck the AI dose into the uterus. This can often occur very quickly and 80 cc will be inseminated within 30 seconds. This can happen with new collapsible bags and bottles. This vacuum is presumed to originate from oxytocin release resulting from neural stimulation of the sow. Often, no vacuum is evident and semen must be deposited with mild pressure. This does not result in reduced pregnancy rates but insemination takes longer. Mild pressure must often be used to begin semen flow. The insemination procedure should require about 2.5 to 3.5 minutes. ...

Most individuals with BTHS are below-average in weight and height, often substantially so. Short stature in early years is often followed by an accelerated growth pattern during mid-to-late phase of puberty. Poor growth is often assumed to be evidence of poor nutrition, but this is not the case. Fortunately, the older boys with BTHS have grown to average and above average heights, but their growth takes longer to come to completion than their peers.. Exercise Intolerance. Symptom severity of BTHS is highly variable, even in families where there is more than one person diagnosed with the condition. Amongst those who have BTHS, some have weaker hearts than others, some have weaker immune systems than others, and some have slower physical developmental rates than others. However, almost all individuals with BTHS suffer from muscle weakness and a general fatigue, which significantly limits their ability to perform normal life activities.. It should be noted again that relatively good health in ...
Health professionals have an important role to play in the management of obesity, but may be unsure how to raise weight issues with patients. The societal stigma associated with excess weight means that weight status terms may be misunderstood, cause offence and risk upsetting patient-professional relationships. This study investigated the views of people who were overweight or obese on the acceptability of weight status terms and their potential to motivate weight loss when used by health professionals. A qualitative study comprising 34 semi-structured interviews with men and women in their mid-to-late 30s and 50s who were overweight or obese and had recently been informed of their weight status. Thematic framework analysis was conducted to allow the systematic comparison of views by age, gender and apparent motivation to lose weight. Although many people favoured Overweight to describe their weight status, there were doubts about its effectiveness to motivate weight loss. Terms including BMI (
In March 1970, most of Browns mid-to-late 1960s road band walked out on him due to money disputes, a development augured by the prior disbandment of The Famous Flames singing group for the same reason in 1968. Brown and erstwhile Famous Flames singer Bobby Byrd (who chose to remain in the band during this tumultuous period) subsequently recruited several members of the Cincinnati-based The Pacemakers, which included Bootsy Collins and his brother Phelps Catfish Collins; augmented by the remaining members of the 1960s road band (including Fred Wesley, who rejoined Browns outfit in December 1970) and other newer musicians, they would form the nucleus of The J.B.s, Browns new backing ensemble. Shortly following their first performance together, the band entered the studio to record the Brown-Byrd composition, Get Up (I Feel Like Being a) Sex Machine; the song and other contemporaneous singles would further cement Browns influence in the nascent genre of funk music. This iteration of the ...
Uncovering the motifs of a higher order nuclear architecture and its implications on nuclear function has raised increasing interest in the past decade. The nucleus of higher eukaryotes is considered to display a highly dynamic interaction of DNA and protein factors. There is an emerging view that there are hierarchical levels of gene regulation, reaching from epigenetic modifications at the DNA- and histone level to a higher order functional nuclear topology, in the context of which gene-activating and -repressing processes influence the gene expression profile of an individual cell beyond the sequence information of the DNA. The present work focuses on the analysis of the dynamic aspects of higher order nuclear architecture in living cells. As a prerequisite, an in vivo replication labeling strategy was developed, that enabled the simultaneous visualization of early and mid-to-late replicating chromatin as well as single chromosome territories on the basis of a labeling/segregation approach. ...

mid-to-late March 2019. Unlike prior years, the OFCCP will not be sending its traditional advanced notification letters to government contractors (including subcontractors) identified as potential targets for compliance evaluations. Instead, the OFCCP will simply post the CSAL in the agencys online Freedom of Information Act (FOIA) library for public viewing.
