BACKGROUND & AIMS: Ovulation induction has been proven to impose oxidative stress during ICSI treatment cycle. Also, data indicates that PCOS women show higher oxidative markers. Available data are not convincing about which antioxidant supplements have the potential to overcome oxidative stress in PCOS subjects. The aim of this trial was to investigate the possible role of combined vitamin E and D supplementation in the ICSI outcomes (oocyte number and quality, embryo number and quality, pregnancy rate) of PCOS subjects...

The process of development depends on a progressive sequence of events that are carefully orchestrated by a number of signalling systems. Alteration in these signalling events results in infertility and neurodevelopmental diseases such as attention deficit hyperactivity disorder (ADHD), autism spectrum disorders (ASD) and schizophrenia. A prominent role throughout development beginning at fertilization and continuing through early development, implantation and organ differentiation such as heart and brain development is regulated by Ca(2+) signalling...

Male factor infertility (MFI) is a growing health issue in society. The vitamin D receptor gene (VDR) is expressed in many tissues and modulates expression of several other genes. The purpose of this study was to investigate the association between MetSyn, VDR gene (FokI, rs-2228570; C > T) polymorphisms and MFI in Indian adults. Fifty cases and fifty-four controls, fulfilling inclusion and exclusion criteria, were included with their informed consent. Fasting plasma glucose, triglyceride, HDL-C were estimated by clinical chemistry analyzer (Beckmam Coulter DXC 800, USA)...

BACKGROUND: The importance of vitamin D in general health as well as in human reproductive success has been an area of focus. A better understanding of vitamin D metabolism, particularly vitamin D binding protein, is important when elucidating this relationship. METHODS: This case control trial seeks to characterize vitamin D metabolism in infertile patients undergoing natural cycle IVF as compared to normally cycling premenopausal women with proven fertility matched for age and body mass index (BMI)...

CONTEXT: Human and animal data suggest that low vitamin D (25-hydroxyvitamin D) status is associated with impaired fertility, endometriosis, and polycystic ovary syndrome. Vitamin D regulates antimullerian hormone (AMH), FSH, mRNA, and expression of genes in reproductive tissues, implicating a role in female reproduction. AIMS: To study the vitamin D levels in infertile females and to know the correlation of vitamin D deficiency (VDD) with serum AMH in infertile females compare to fertile females...

REVIEW
Audrey J Gaskins, Jorge E Chavarro
The literature on the relationship between diet and human fertility has greatly expanded over the last decade, resulting in the identification of a few clear patterns. Intake of supplemental folic acid, particularly at doses higher than those recommended for the prevention of neural tube defects, has been consistently related to lower frequency of infertility, lower risk of pregnancy loss, and greater success in infertility treatment. On the other hand and despite promising evidence from animal models, vitamin D does not appear to exert an important role in human fertility in the absence of deficiency...

OBJECTIVE: Hyperstimulation methods are broadly used for in vitro fertilization (IVF) in patients with infertility; however, the side effects associated with these therapies, such as ovarian hyperstimulation syndrome (OHSS), have not been well studied. N-glycoproteomes are subproteomes used for the remote sensing of ovarian stimulation in follicular growth. Glycoproteomic variation in human follicular fluid (hFF) has not been evaluated. In this study, we aimed to identify and quantify the glycoproteomes and N-glycoproteins (N-GPs) in natural and stimulated hFF using label-free nano-liquid chromatography/electrospray ionization-quad time-of-flight mass spectrometry...

BACKGROUND: A couple may be considered to have fertility problems if they have been trying to conceive for over a year with no success. This may affect up to a quarter of all couples planning a child. It is estimated that for 40% to 50% of couples, subfertility may result from factors affecting women. Antioxidants are thought to reduce the oxidative stress brought on by these conditions. Currently, limited evidence suggests that antioxidants improve fertility, and trials have explored this area with varied results...

The role of vitamin D in female reproduction has been intensively examined over the last few decades. A large body of evidence suggests that vitamin D might have beneficial effects on metabolic/hormonal parameters of PCOS and endometriosis, while it appears to be associated with IVF outcomes. However, due to the heterogeneity among observational and interventional studies, no cause-effect relationship has yet been established. The aim of this review is to analyze recent in vitro animal and human studies which examined the association of vitamin D with disease entities affecting female fertility potential...

A large number of evidence supports the role of vitamin D insufficiency in both women and men infertility. However, no studies have evaluated the rate of concordance of vitamin D status between the partners. This finding might open new scenarios in the interpretation of the available data linking vitamin D insufficiency and infertility. In the present cross-sectional study, 103 consecutive infertile couples were recruited between April and May 2014. Both partners concomitantly provided a serum sample for the assessment of 25-hydroxy-vitamin D [25-(OH)-D]...

Androgens and estrogens play a key role regarding sexual life and reproduction. Along with hypotestosteronemia, obese men exhibit a 2-fold increase in estradiol concentration, adversely infl uencing these parameters. Estrogens and adipokines also infl uence bone metabolism, exerting a direct effect on vitamin D, calcium homeostasis and bone health. Bariatric procedures normalize some sex hormones, and may reverse several obesity-related conditions. Estrogens levels may remain elevated postoperatively, and despite its protective effect on the skeleton, bariatric patients are more prone to fractures when compared to the general population...

Since the passage of Title IX in 1972, female sports participation has dramatically increased. The benefits of physical activity, including decreased risk for heart disease and diabetes as well as improved body image and self-esteem, far outweigh the risks. However, a select population of adolescent and young adult females may experience symptoms related to the female athlete triad (Triad), which refers to the interrelatedness of energy availability, menstrual function, and bone mineral density (BMD). These conditions often manifest clinically as disordered eating behaviors, menstrual irregularity, and stress fractures; an individual may suffer from 1 or all of the Triad components simultaneously...

BACKGROUND: Infertility is a global public health issue, affecting 15% of all couples of reproductive age. Male factors, including decreased semen quality, are responsible for ~25% of these cases. The dietary pattern, the components of the diet and nutrients have been studied as possible determinants of sperm function and/or fertility. OBJECTIVE AND RATIONALE: Previous systematic reviews have been made of the few heterogeneous low-quality randomized clinical trials (RCTs) conducted in small samples of participants and investigating the effect of specific nutrients and nutritional supplements on male infertility...

Endometriosis is a hormone-dependent chronic inflammatory disease characterized by the presence of endometrium beyond the uterine cavity. The disease affects 5-15% of women of child-bearing age, 30-50% of whom suffer from infertility. Understanding the role of dietary factors in the development of endometriosis is critical to development of effective dietary instructions for prevention. Existing studies concerning nutrition and endometriosis suggest that diet is a potentially modifiable risk factor for endometriosis...

Endometriosis is a common female reproductive disease characterized by invasion of endometrial cells into other organs, frequently causing pelvic pain and infertility. Alterations of the vitamin D system have been linked to endometriosis incidence and severity. To shed light on the potential mechanism for these associations, we examined the effects of 1,25(OH)2D3 on gene expression in endometriosis cells. Stromal cell lines derived from endometriosis tissue were treated with 1,25(OH)2D3, and RNA-seq was used to identify genes differentially expressed between treated and untreated cells...

We present a nulliparous woman with mild to moderate ulcerative colitis (UC) and multiple failed cycles of in vitro fertilization (IVF) in whom we achieved a successful, viable pregnancy following clinical and endoscopic UC remission. Infertile patients with inflammatory bowel disease who have failed multiple cycles of IVF should try to achieve clinical remission and mucosal healing (absence of erosions or ulcers) prior to reattempting conception. Furthermore, deficiencies in vitamin B12, vitamin D, and iron should be addressed...
