PURPOSE: This study investigated the relationship between the vitamin D [25(OH)D] level in individual follicles and oocyte developmental competence. METHODS: A prospective cohort study in a private infertility center. Infertile women (N = 198) scheduled for intracytoplasmic sperm injection (ICSI) and a single embryo transfer (SET) provided serum samples and 322 follicular fluid (FF) specimens, each from a single follicle on the day of oocyte retrieval. RESULTS: FFs corresponding to successfully fertilized oocytes (following ICSI) contained significantly lower 25(OH)D level compared with those that were not fertilized (28...

Nonclassical target organs recently defined for vitamin D, a major regulator of calcium phosphorus homeostasis and bone health, include reproductive ones. This compilation study focuses on the potential effects of vitamin D on female reproductive functions. Vitamin D receptor enzymes that metabolize vitamin D are expressed in both central and peripheral reproductive organs. Most studies suggest that vitamin D may be directly or indirectly related to gonadal functions. Vitamin D's effects on reproductive functions may be indirectly related to diseases such as polycystic ovary syndrome (PCOS), uterine leiomyomas, and endometriosis...

In this paper, 153 infertile women undergoing induction of ovulation at an academic tertiary care centre were included in a cross-sectional study. Serum Vitamin D level was measured and the rate of clinical pregnancy (defined as a sonographic presence of FHR of an intrauterine gestational sac) and patient and cycle parameters were determined. The results showed that a correlation exists between endometrial thickness as well as the number of antral follicles and replete level of Vitamin D. Interestingly, the median level of these two parameters was of upmost level in the most replete tertile of serum Vitamin D level...

Vitamin D receptor-knockout mice fail to produce mature oocytes, indicating vitamin D is crucial for folliculogenesis in mice. However, the actions of vitamin D during folliculogenesis remain unknown. This prospective study aimed to assess whether follicular fluid (FF) vitamin D (25OHD3) concentrations are related to specific responses to ovarian stimulation. Women undergoing ovarian stimulation for IVF participated in the study. FF 25OHD3 concentrations were assessed in the first follicle aspirate on oocyte retrieval day...

Lead toxicity is a major public health issue in developed and developing countries. Both acute and chronic lead exposure has the potential to cause many deleterious systematic effects including hypertension, frank anemia, cognitive deficits, infertility, immune imbalances, delayed skeletal and deciduous dental development, vitamin D deficiency, and gastrointestinal effects. The underlying mechanisms for all these systemic effects have not been elucidated completely. However, the most plausible cause is free radical damage...

The aim of the study was to evaluate the effects of administration of 25-hydroxyvitamin D [25(OH) D] on serum antimullerian hormone (AMH) levels in infertile women. The study was performed as a non-randomized clinical trial on 30 infertile women who had low serum level of both 25(OH) D and anti-mullerian hormone. Vitamin D was prescribed 50,000 IU weekly for up to three months for all eligible participants. Serum levels of both 25(OH) D and AMH have increased significantly after treatment with 25(OH) D. There was a significant correlation between serum levels of 25(OH) D after treatment with AMH (p = ...

Catherine King, Lorraine Harper
Purpose of review With established immunosuppressant treatment regimens for anti-neutrophil cytoplasm antibody-associated vasculitides (AAV), prognosis has significantly improved. The mainstay of treatment still comprises high-dose corticosteroids and cyclophosphamide for severe forms, although rituximab is being increasingly utilised instead of cyclophosphamide as induction therapy. AAV patients experience an excess of infections, malignancies and cardiovascular events as compared to the general population, which is a combination of the systemic inflammatory process associated with vasculitis and the adverse events from treatment...

BACKGROUND: Uterine leiomyoma (also known as fibroid or myoma) is the most common benign tumor of the uterus found in women of reproductive age. It is not usually fatal but can produce serious clinical symptoms, including excessive uterine bleeding, pelvic pain or pressure, infertility and pregnancy complications. Due to lack of effective medical treatments surgery has been a definitive choice for the management of this tumor. OBJECTIVE AND RATIONALE: Extracellular matrix (ECM) accumulation and remodeling are thought to be crucial for fibrotic diseases such as uterine leiomyoma...

The process of development depends on a number of signaling systems that regulates the progressive sequence of developmental events. Infertility and neurodevelopmental diseases, such as attention deficit hyperactivity disorder, autism spectrum disorders, and schizophrenia, are caused by specific alterations in these signaling processes. Calcium signaling plays a prominent role throughout development beginning at fertilization and continuing through early development, implantation, and organ differentiation such as heart and brain development...

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...
