Transmitted Infection

The human papillomavirus (HPV) is a sexually transmitted infection common among men and women across all geographic and socioeconomic subgroups worldwide. Recent evidence suggests that HPV infection may affect fertility and alter the efficacy of assisted reproductive technologies. In men, HPV infection can affect sperm parameters, specifically motility. HPV-infected sperm can transmit viral DNA to oocytes, which may be expressed in the developing blastocyst. HPV can increase trophoblastic apoptosis and reduce the endometrial implantation of trophoblastic cells, thus increasing the theoretical risk of miscarriage. Vertical transmission of HPV during pregnancy may be involved in the pathophysiology of preterm rupture of membranes and spontaneous preterm birth. In patients undergoing intrauterine insemination for idiopathic infertility, HPV infection confers a lower pregnancy rate. In contrast, the evidence regarding any detrimental impact of HPV infection on IVF outcomes is inconclusive. It has been suggested that vaccination could potentially counter HPV-related sperm impairment, trophoblastic apoptosis, and spontaneous miscarriages; however, these conclusions are based on in vitro studies rather than large-scale epidemiological studies. Improvement in the understanding of HPV sperm infection mechanisms and HPV transmission into the oocyte and developing blastocyst may help explain idiopathic causes of infertility and miscarriage.

The Impact

Human papilloma virus (HPV) is one of the most prevalent viral sexually transmitted diseases. The ability of HPV to induce malignancy in the anogenital tract and stomato-pharyngeal cavity is well documented. Moreover, HPV infection may also affect reproductive health and fertility. Although, the impact of HPV on female fertility has not been thoroughly studied it has been found also to have an impact on semen parameters. Relative information can be obtained from studies investigating the relationship between HPV and pregnancy success. Furthermore, there is an ongoing debate whether HPV alters the efficacy of assisted reproductive technologies. An association between HPV and assisted reproductive technologies (ART) programs has been reported. Nevertheless, due to conflicting data and the small number of existing studies further research is required. It remains to be clarified whether HPV detection and genotyping could be included in the diagnostic procedures in couples undergoing in vitro fertilization (IVF)/intrauterine insemination (IUI) treatments. Vaccination of both genders against HPV can reduce the prevalence of HPV infection and eliminate its implications on human fertility. The aim of the present mini-review is to reiterate the association between HPV and human fertility through a systematic literature review.

Graphic Description

What’s a Lemon Squeezer Doing in My Vagina? is a memoir of Rohini S Rajagopal’s excruciating five-year long fight with infertility and her journey to motherhood. After several failed attempts at natural conception and many negative home pregnancy tests, the author and her husband Ranjith visit a fertility centre in Bangalore. Rajagopal delivers a graphic description of the physical and emotional unpleasantness of her infertility treatment and also gives a vivid account of her experiences with the assisted reproductive technologies (ARTs) such as the intrauterine insemination (IUIs), in-vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI). Intrauterine Insemination (IUI) is facilitated by directly injecting a man’s sperm into the woman’s uterus around the time the eggs emerge from the ovaries.

Genomic Imprints

Abstract Background Epidemiological studies suggest that singletons born from assisted reproductive technologies (ART) have a high risk of adverse perinatal outcomes, specifically for imprinting disorders. Because ART processes take place at times when epigenetic reprogramming/imprinting are occurring, there is concern that ART can affect genomic imprints. However, little is currently known about the risk of imprinting defects according to the type of ART or the type of underlying female infertility. From the French national health database, a cohort of 3,501,495 singletons born over a 5-year period (2013–2017) following fresh embryo or frozen embryo transfers (fresh-ET or FET from in vitro fertilization), intrauterine insemination, or natural conception was followed up to early childhood. Based on clinical features, several syndromes/diseases involving imprinted genes were monitored. The effects of ART conception and the underlying cause of female infertility were assessed. Results Compared with infants conceived naturally, children born after fresh-ET had a higher prevalence of imprinting-related diseases, with an aOR of 1.43 [95% CI 1.13–1.81, p = 0.003]. Namely, we observed an increased risk of neonatal diabetes mellitus (1.96 aOR [95% CI 1.43–2.70], p < 0.001). There was an overall independent increase in risk of imprinting diseases for children with mothers diagnosed with endometriosis (1.38 aOR [95% CI 1.06–1.80], p = 0.02). Young and advanced maternal age, primiparity, obesity, smoking, and history of high blood pressure or diabetes were also associated with high global risk. Conclusions This prospective epidemiological study showed that the risk of clinically diagnosed imprinting-related diseases is increased in children conceived after fresh embryo transfers or from mothers with endometriosis. The increased perturbations in genomic imprinting could be caused by controlled ovarian hyperstimulation and potentially endometriosis through the impairment of endometrial receptivity and placentation, leading to epigenetic feto-placental changes. Further studies are now needed to improve understanding of the underlying molecular mechanisms (i.e. genetic or epigenetic causes).

Introduction. Sperm morphology is one of the most common tests in fertility practice. The interlaboratory variability is the main drawback of the method. The clinical significance of sperm morphology in assisted reproductive technologies is controversial. The aim of the review is to address this question. Materials and methods. The search of relevant publications was carried out in PubMed and e-Library databases using the keywords «male infertility», «sperm morphology», «teratozoospermia», «IUI», «IVF», «ICSI». Conference abstracts and dissertations were excluded from analysis and 56 publications were included in this literature review. Results. The small numbers of studies were evaluated to the effect of teratozoospermia on the likelihood of natural pregnancy. The pregnancy rate was higher in the group of couples with normozoospermia. In the couples with severe teratozoospermia pregnancies rate was also detected. The most studies did not reveal a statistically significant effect of tertozoospermia on the frequency of pregnancy during intrauterine insemination. The data about the influence of sperm morphology on in vitro fertilization are contradictory. Early studies showed a positive correlation between normal sperm morphology and frequency of conception, but these results were not confirmed in further studies. The most studies have not been revealed the correlation between normal sperm morphology male fertility status, clinical and live birth rate. Discussion. To date the spermatozoa mofophology studying remains the «starting point» ofa man's examination for infertility. However, the data available do not confirm its role in choosing the method ofassisted reproductive technologies or predicting their results. Conclusions. To date the role of sperm morphology on conceive and pregnancy frequencies in ART use is controversal. The data available does not confirm the value of this test as a proxy of higher pregnancy and birth of healthy child probability. The further studies are required to address this question.

The swamp buffalo holds tremendous potential in the livestock sector in Asian and Mediterranean countries. Current needs are the faster multiplication of superior genotypes and the conservation of endangered buffalo breeds. Recent advances in assisted reproductive technologies, including in vitro embryo production methodologies, offer enormous opportunities to not only improve productivity, but also to use buffaloes to produce novel products for applications to human health and nutrition. The use of molecular genomics will undoubtedly advance these technologies for their large-scale application and resolve the key problems currently associated with advanced reproductive techniques, such as animal cloning, stem cell technology and transgenesis. Preliminary success in the application of modern reproductive technologies warrants further research at the cellular and molecular levels before their commercial exploitation in buffalo breeding programmes.

Reproductive technologies are those technologies that aid in animal and human reproduction. Assisted reproductive technologies (ARTs) are more narrowly defined as those technologies that help people suffering from social or bodily infertility create a family. Socially infertile includes single women and men as well as homosexual couples who rely on donated gametes for the creation of a future child. Intrauterine Insemination (IUI) is usually the first step taken by couples having trouble conceiving. The most general type of reproduction technology is in vitro fertilization (IVF), which means that the egg is retrieved from a woman’s uterus and sperm is introduced to these eggs in a petri dish. In the case of male infertility, intracytoplasmic sperm injections (ICSI) may be employed, which means that sperm are injected directly into the egg. IVF may include the use of donated sperm, oocytes, and embryos. In addition to gamete donation, surrogacy may be employed in cases where an intended mother or intended gay fathers cannot carry a pregnancy to term. In addition to being used to create families, contraception is also considered a reproductive technology. Anthropologists have been conducting ethnographic analyses of reproductive technologies by studying the people intimately engaged with these varying technologies. Scholarship revolves around major questions about markets and gift exchange, kinship, and how our understandings of family have shifted with the advent of reproductive technologies, as well as globalization and the ways in which bodies, people, and technologies traverse the globe.

The Relationship

The aim of the study is to systematically analyze the data available in the modern literature on the relationship between endometrial thickness and the frequency of pregnancy in the program of assisted reproductive technologies (ART). Materials and methods. The review includes data from foreign and domestic articles found in PubMed on this topic. Results. The article presents data on the relationship between the thickness of the endometrium and the frequency of pregnancy in ART programs. The greatest number of studies is devoted to the evaluation of the relationship between the thickness of the endometrium and the frequency of pregnancy on the day of the ovulation trigger. Data are presented on the existence of a correlation between the thickness of the endometrium measured on the day of the ovulation trigger and the frequency of clinical pregnancy, as well as data on the need to evaluate the structure of the endometrium and the state of subendometric blood flow. The importance of multilayered (three-layered) endometrium as a prognostic marker of success in in vitro fertilization/intracytoplasmic sperm injection programs in the ovum is emphasized. The conclusion. The thickness of the endometrium can not be used as an argument for canceling the cycle or abolishing embryo transfer to the uterine cavity. Further studies in this direction are needed with a study of the morphological and molecular genetic characteristics of the endometrium, which in the future will allow us to evaluate the relationship between the thickness of the endometrium and the probability of pregnancy.
