Introduction & Objective: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. According to the Rotterdam criteria, this syndrome is identified by presence of two of three criteria: (1) polycystic ovaries (2) oligo/anovulation and/or (3) clinical or biochemical evidence of hyperandrogenism. Low mature oocyte and embryo have been reported in poly...
Background: The biochemical characteristics of the follicular fluid (FF) play essential role in oocyte quality, the subsequent fertilization potential and embryo development. The oocyte quality and metabolism largely depends on follicular microenvironment. Present study aimed to investigate the relationship between oocyte quality and FF homocysteine (Hcy) level in women undergoing to IVF treatm...
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
oocyte maturation and embryo development are controlled by intra-ovarian factors such as steroid hormones. progesterone (p4) exists in the follicular fluid that contributes to normal mammalian ovarian function and has several critical functions during embryo development and implantation, including endometrial receptivity, embryonic survival during gestation and transformation of the endometrial...
Background: Diabetes mellitus is a metabolic condition characterized by elevated blood glucose levels secondary to absolute impairment of insulin secretion. Maternal diabetes has been demonstrated to adversely affect pre implantation embryo development and pregnancy outcomes. Emerging evidence has implicated that these effects are associated with compromised oocyte competence. Several developme...
background: polycystic ovaries syndrome (pcos) is the most common disorder in infertile women with ovulation sterility. there are some instances of abnormal endocrine in the women stricken by this syndrome and so the clinical results of ovulating induction in them, because of severe response of ovary against ovulating induction, are very discussing and may lead to different results from those w...
Background: The aim of our study was to determine the metabolic profile: glucose, triglycerides (TG), high density lipoprotein (HDL) and cholesterol (CHT) in women undergoing ART (Assisted reproductive technology) cycles and estimate its effect on In Vitro Fertilization (IVF) outcomes Materials and Methods: Forty three women undergoing IVF treatment were included in the study. Patients were all...
Background and Purpose: In vitro maturation of oocyte is a promising technology in treatment of infertility, however, its clinical application is still limited due to poor success rate. This study was devised to evaluate the effect of mouse embryo tail bud co-culture on maturation of immature mouse oocyte. Materials and Methods: Immature oocytes were recovered from NMRI female mice 48hr after ...
