The role of autoantibodies in in vitro fertilization (IVF) has been discussed for almost three decades. Nonetheless, studies are still scarce and widely controversial. The aim of this study is to provide a comprehensive systematic review on…

PURPOSE: The aim of this prospective randomized control trial was to evaluate if the use of two different volumes (20-25 vs 40-45 μl) of media used for embryo transfer affects the clinical outcomes in fresh in vitro fertilization (IVF) cycl…

Among uterine structural abnormalities, myomas and adenomyosis represent two distinct, though frequently coexistent entities, with a remarkable prevalence in women of reproductive age. Various mechanisms have been proposed to explain the im…

Endometriosis represents a main cause of infertility and pelvic pain affecting 3-43% among reproductive age women. Deep pelvic endometriosis is defined as subperitoneal infiltration of endometrial implants in the uterosacral ligaments, rect…

OBJECTIVE: To evaluate the efficacy of continuous oral contraceptive (OC) use versus the usual cyclic fashion in the recurrence of endometriosis-related symptoms after surgery. DESIGN: Prospective cohort trial involving patients in two ter…

BACKGROUND: Studies suggested that microRNAs influence cellular activities in the uterus including cell differentiation and embryo implantation. In assisted reproduction cycles, luteal phase support, given to improve endometrial characteris…

There is evidence that endometriosis as well as drugs used in the process of in vitro fertilisation appear to associate with increased risk for gynaecological cancer. In this review, we attempt to describe this relationship according to the…

unaffected by gonadal hormones, so blood samples may be collected at any time during the menstrual cycle. AMH has been shown to be associated with oocyte yield in IVF, and some studies suggest that AMH is related to treatment outcome (for r…

PURPOSE: Our purpose was to investigate whether the addition of exogenous leuteinizing hormone (LH) increases estradiol secretion in LH-depleted women undergoing controlled ovarian hyperstimulation (COH) with purified follicle stimulating h…

After completing this lesson, the participant will be familiar with the epidemiology, pathophysiology, and etiology of pelvic pain, and be able to develop a s.ystematic diagnostic approach and strategic plan for the management of patients w…
