In an in vitro fertilization program, approximately 10-15% of oocytes obtained after controlled ovarian stimulation are immature, with germinal vesicles (GVs). These oocytes are usually discarded in clinical practice; however, an in vitro maturation (IVM) procedure can be applied to mature them. There are scarce data in the literature on the effect of IVM on the expression of important development- and zona pellucida (ZP)-related genes in human oocytes; therefore, we wanted to determine this.

However, this method is still sparsely researched and used in clinical practice, leading to suboptimal clinical results. Anti-Müllerian hormone (AMH) is an important hormone with known effects on human ovaries, especially on follicles (follicular cells) during folliculogenesis.

Patients And Methods: After ovarian stimulation in cancer patients, the number of oocytes and their quality and maturity were compared to control patients with fertility problems in the fertilization (IVF) program. In both groups of patients, immature oocytes at the developmental stage of germinal vesicle were matured and the proportion of oocytes that matured was compared between groups.
Oxidative stress in the follicular fluid (FF) is thought to be responsible for the abnormal development of oocytes. In our study patients with polycystic ovarian syndrome (PCOS), endometriosis, and tubal infertility factor (TIF), and healthy women with a male factor of infertility, were prospectively enrolled. From each patient, a sample of individual FF was collected from a dominant follicle.

Purpose: In this review, the current knowledge on anti-Müllerian hormone (AMH) is presented, concerning its value in disease and IVF treatment as well as in terms of its prospective clinical use.
Methods: AMH is becoming the most appropriate biomarker for the ovarian reserve measured predominantly for assisted reproductive treatment (ART) patients in comparison to the currently used antral follicle count (AFC). However, this is not the only way AMH measurements can be used in the clinics.
