Aim: The aim of this study is to investigate the role of vitamin E in the etiology of premature ovarian insufficiency (POI).
Methods: This study included a total of 96 matched cases and controls, including the case group composed of 40 women with POI, and the control group composed of 56 women with normal menstrual cycles. Serum levels of vitamin E (also known as α-tocopherol), total cholesterol, follicle stimulating hormone (FSH), luteinizing hormone (LH) and anti-Müllerian hormone (AMH) were determined. The relationship of α-tocopherol with FSH, LH and AMH levels in women were evaluated using regression models.
Results: We found a negative association of α-tocopherol levels with FSH and LH levels, and a positive correlation between a-tocopherol and AMH levels in the whole study population. In this study, α-tocopherol levels were significantly lower in women with POI than those in women with normal menstrual cycles.
Conclusion: Vitamin E levels showed significantly statistical difference between the POI and control group (P < 0.001). Therefore, vitamin E is correlated to POI.

Oxidative stress (OS) is established as a key factor in the etiology of both male and female infertility, arising from an imbalance between reactive oxygen species (ROS) production and the endogenous antioxidant (AOX) defenses. In men, OS adversely affects sperm function by inducing DNA damage, reducing motility, significantly impairing sperm vitality through plasma membrane peroxidation and loss of membrane integrity, and ultimately compromising overall sperm quality. In women, OS is implicated in various reproductive disorders, including polycystic ovary syndrome, endometriosis, and premature ovarian failure, leading to diminished oocyte quality, disrupted folliculogenesis, and poorer reproductive outcomes.

Introduction: Infertility is a very discussed problem in many endocrinological and gynecological courses and congresses. In a rapidly revolving environment women tend to postpone pregnancy to have security in their financial life and career.We discuss primary and secondary infertility and the hormonal results in women that presented for a desire to conceive with their partner.

REV7, also known as MAD2B, MAD2L2, and FANCV, is a HORMA-domain family protein crucial to multiple genome stability pathways. REV7's canonical role is as a member of polymerase ζ, a specialized translesion synthesis polymerase essential for DNA damage tolerance. REV7 also ensures accurate cell cycle progression and prevents premature mitotic progression by sequestering an anaphase-promoting complex/cyclosome activator.

Introduction: Premature ovarian insufficiency (POI) is a condition characterized by ovarian dysfunction occurring before the age of 40, and its etiology is multifactorial, including genetic, immunological, infectious, environmental, and iatrogenic factors, with over half of the cases remaining unexplained. Whether the microbial communities and metabolites in follicular fluid, which is the direct microenvironment for oocyte survival, are related to POI has not been reported.
Methods: In this study, Follicular fluid samples of 26 patients with POI and 27 controls with a normal ovarian reserve were collected and analyzed using 16S rDNA sequencing and untargeted metabolomics.

Objective: To study the relationship between FK506-binding protein 51 (FKBP51) and ovarian aging and/or diminished ovarian reserve (DOR) in human ovaries by comparing FKBP51 levels in granulosa (GC) and cumulus cells (CC), collected during controlled ovarian stimulation (COS) from women of advanced reproductive age and/or with a diagnosis of DOR with that of young women with normal ovarian reserve. To explore the association between increased FKBP51 expression and human ovarian aging further, expression of FKBP51 was compared in ovarian stroma of post-menopausal versus pre-menopausal women. Lastly, this relation was further queried by comparing ovarian expression of several collagen genes as markers of ovarian fibrosis in 14-month-old wild type (Fkbp5) and Fkbp5 knockout (Fkbp5) mice.
