BACKGROUND: The transfer of cryopreserved embryos can be timed with ovulation in a natural cycle or after artificially preparing the endometrium with exogenous hormones. Progesterone is essential for the secretory transformation of the endo…

BACKGROUND: Different success rate of Intracytoplasmic Sperm injection (ICSI) has been observed in various causes of infertility. In this study, we evaluated the relation between ICSI outcome and different causes of infertility. We also aim…

BACKGROUND: The endometrium plays a pivotal role in implantation and pregnancy. Cyclooxygenase II (COX-2) has an important function in biological processes such as cell proliferation and inflammation. Celecoxib is a selective inhibitor of C…

BACKGROUND: This study compares the microdose flare-up protocol to the ultrashort gonadotropinreleasing hormone (GnRH) agonist flare combined with the fixed multidose GnRH antagonist protocol in poor responders undergoing ovarian stimulatio…

BACKGROUND: To evaluate the impact of the association of endometrioma with or without deep infiltrating endometriosis (DIE) after a first intra cytoplasmic sperm injection- in vitro fertilization (ICSI-IVF) cycle on pregnancy rate. MATERIA…

Women’s health is increasing identified as a global health priority. Women’s health is affected by many factors, such as the economy, environment, society, culture, religion, and biology. For this reason, the Health Policy Research Center, …

BACKGROUND: Endometriosis is known as one of the most common disease in women of reproductive age. Due to important role of vascular endothelial growth factor (VEGF) in neo-vascularization for the implantation of endometrial cell, and also …

BACKGROUND: This study compares the developmental capacity of gametes retrieved from the largest follicle with small follicles of a cohort in controlled ovarian stimulated cycles. MATERIALS AND METHODS: This prospective study performed in …

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 funct…

BACKGROUND: The objective of this study was to identify the prognostic factors that influence the outcome of ovarian stimulation with intrauterine insemination (IUI) cycles in couples with different infertility etiology. MATERIALS AND METH…

BACKGROUND: Human chorionic gonadotropin (HCG), one of the initial embryonic signals, is probably a major regulator of the embryo-endometrial relationship. This study aims to assess the advantage of HCG supplementation during the secretory …

BackgroundThis study investigated the effects of serum estradiol (E2) and progesterone levels on preovulatory endometrial thickness and echogenicity in controlled ovarian hyperstimulation (COH) cycles for in vitro fertilization (IVF).Materi…

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common, complex endocrine disorder for women of productive age. A high incidence of ovulation failure in women with PCOS is related to insulin resistance. Some studies have assessed the effe…

BACKGROUND: Endometriosis is the presence of endometrial glands and stroma in sites other than the uterine cavity, which is associated with infertility. The objective of this study was to evaluate the effect of laparoscopic surgical treatme…

BACKGROUND: This study evaluated the characteristics and results of patients who suffer from recurrent implantation failure (RIF). MATERIALS AND METHODS: In this cross sectional study, a total of 2183 cases who were evaluated retrospective…
