Materials and Methods: This prospective study was performed on 70 patients undergoing controlled ovarian hyperstimulation and followed by the IVF Department between February 2009-June 2009. Age, body mass index (BMI), basal levels of folliclestimulating hormone (FSH), estradiol (E2), luteinizing hormone (LH), ovarian volume, and number of antral follicles were compared between the good responde...

Aim: We sought to create and describe a self-made simulator designed created for teaching purposes: high-fidelity ultrasound phantom demonstrating antral follicle count, supervision of controlled ovarian stimulation, ultrasound-guided oocyte retrieval. Materials methods: The uterus ovaries the were made from beef tongue, male condom, latex gloves, cotton suture threads, bi-distilled water, gel....

background: it is reasonable to think that some biochemical characteristics of follicular fluid (ff) surrounding the oocyte may play a critical role in determining the quality of oocyte and the subsequent potential needed to achieve fertilization and embryo development. objective: this study was carried out to evaluate the levels of ff homocysteine (hcy) in ivf candidate polycystic ovary syndro...

OBJECTIVE To determine the clinical potential of donor-oocyte cryopreservation and thaw techniques for recipient patients. DESIGN Institutional review board-approved prospective study of donor oocyte cryopreservation. SETTING A large, private infertility center. PATIENT(S) Four anonymous oocyte donors underwent ovarian hyperstimulation for the purpose of oocyte retrieval and cryopreservat...

Maturation arrest of human oocytes may occur at various stages of the cell cycle. A total failure of human oocytes to complete meiosis is rarely observed during assisted conception cycles. We describe here a case series of infertile couples for whom all oocytes repeatedly failed to mature during IVF/ICSI. Eight couples, all presenting with unexplained infertility, underwent controlled ovarian s...

OBJECTIVE To preliminarily study the feasibility of oocyte cryopreservation in postpubertal girls aged between 13 and 15 years who were at risk for premature ovarian failure due to the accelerated follicle loss associated with Turner syndrome or cancer treatments. DESIGN Retrospective cohort and review of literature. SETTING Academic fertility preservation unit. PARTICIPANTS Three girls d...

The significance of the presence of coarse dark granules in the perivitelline space of oocytes has not been studied before. The study included 2288 intact oocytes [2063 in metaphase II (MII), 136 in metaphase I (MI), and 89 in germinal vesicle (GV)] retrieved in 206 intracytoplasmic sperm injection cycles stimulated by a long agonist protocol. The incidence of granules varied with oocyte maturi...

Embryo transfer policy and luteal supplementation was reviewed, comparing literature data and the results from the Maribor IVF Centre. A retrospective analysis of 1024 cycles in patients undergoing IVF, intracytoplasmic sperm injection (ICSI) or testicular sperm aspiration in unstimulated cycles was carried out using four different approaches for cycle monitoring. This showed that the most succ...

Recent findings In random-start protocols, the number of total and mature oocytes retrieved, oocyte maturity rate, mature oocyte yield and fertilization rates are similar to those in conventional (early follicular phase start) protocols. Starting ovarian stimulation in the late follicular or luteal phase did not show any superiority against the other. The presence of corpus luteum or luteal pha...

Empty follicle syndrome (EFS) is a condition in which no oocytes are obtained after an apparently successful ovarian stimulation. Genuine EFS (GEFS) is differentiated from false EFS by an optimal level of human chorionic gonadotropin on the day of oocyte retrieval. Some believe that GEFS does not exist and that it is only a reflection of the margin of error attendant upon the procedure of oocyt...
