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...
BACKGROUND The aim of this study was to investigate whether a pre-incubation time between oocyte retrieval and insemination or injection had any effect on the success rate of IVF or intracytoplasmic sperm injection (ICSI). Based on previously published data, many laboratories retain a time interval of several hours between oocyte retrieval and insemination/injection. In our setting, inseminatio...
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...
