PURPOSE Pelvic inflammatory disease is a rare complication of transvaginal oocyte retrieval. It results in failure of assisted reproductive procedure. PATIENTS During a 6-year period, 5958 transvaginal ultrasound-guided oocyte retrievals resulted in 10 cases of acute pelvic inflammatory disease (0.12%). RESULTS Eight of the 10 patients were diagnosed infertile because of endometriosis. Two ...

To evaluate the relationship between endometrial thickness during fresh in vitro fertilization (IVF) cycles and the clinical outcomes of subsequent frozen embryo transfer (FET) cycles.FET cycles using at least one morphological good-quality blastocyst conducted between 2012 and 2013 at a university-based reproductive center were reviewed retrospectively. Endometrial ultrasonographic characteris...

BACKGROUND A pre-ovarian block (POB) technique can be used for pain relief during oocyte retrieval in IVF. The local anaesthetic is deposited in the vaginal wall and between the vaginal wall and the peritoneal surface near the ovary using ultrasound guidance. The aim of this study was to test whether analgesia with POB resulted in improved pain relief compared to paracervical block (PCB). MET...

BACKGROUND This randomized controlled study was performed in an unselected IVF/ICSI population to test the hypothesis that blastocyst transfers result in higher clinical pregnancy rates (CPR) per oocyte retrieval when compared with day 2 transfers. METHODS Blind randomization for transfer on day 2 (group 1) or day 5/6 (group 2) was performed before stimulation. Oocytes and embryos were cultur...

The means by which endometrial receptivity influences conception rates in assisted reproductive technology (ART) is poorly understood. As the glycoprotein CA-125 is a product of human endometrium and is measurable in the peripheral circulation, it was investigated whether it might serve as an indicator of endometrial receptivity and predictor of pregnancy. In this prospective study, serum CA-12...

Objective. To test if serum hCG levels the morning after the ovulatory hCG injection correlate with (1) retrieval efficiency, (2) oocyte maturity, (3) embryo quality, (4) pregnancy, and/or (5) time to implantation in patients undergoing in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI). Design. Retrospective cohort analysis. Setting. University-based IVF clinic. Patient(...

The efficiency of three oocyte collection methods from goat ovaries was assessed. Oocytes were collected by aspiration (n=165), slicing (n=213) and puncture (n=172). The mean yield of oocytes per ovary was found to be 3.93 ± 0.11, 4.44 ± 0.06 and 3.59 ± 0.07 by aspiration, slicing and puncture respectively. Slicing yielded significantly higher number of oocytes per ovary. Percentage yield of cu...

The cumulus-oocyte complex (COC) is an oocyte surrounded by specialized granulosa cells, called cumulus cells. cells surrounding the ensure healthy and embryo development. maturity of COCs at retrieval may be used as indicator to predict outcome assisted reproductive technology (ART). Segmenting a preliminary step in many image processing pipelines evaluate maturity. However, acquiring well-ann...
