A total of 37 percutaneous epididymal sperm aspiration (PESA) and/or testicular sperm aspiration (TESA) procedures were performed under local anaesthesia (LA) on 34 men between June and November 1996. Local anaesthesia was achieved by injecting 10 ml of 1% lignocaine solution along the sides of the vas deferens near the external inguinal ring (spermatic(More)
An analysis of 581 in-vitro fertilization treatment cycles was carried out to determine the pattern of utilization of retrieved oocytes. Patients were divided into five groups depending on the number of retrieved oocytes. The mean fertilization rate of 57% was broadly similar amongst the groups but the proportion of retrieved oocytes that produced embryos(More)
A retrospective study was carried out to assess the potential of 16 hysterectomized women to achieve surrogate pregnancies. A total of 11 patients completed 16 cycles of assisted conception treatment incorporating in-vitro fertilization and gestational surrogacy. Three other women failed to respond to ovulation induction while two more patients produced few(More)
A 48 year old African American woman presented with bladder pressure leading to the diagnosis of broad ligament and multiple uterine leiomyomas. She was also found to have a lateral vaginal wall mass which was confirmed to be a leiomyoma. Unlike uterine leiomyomas, vaginal leiomyomas are uncommon and are most often found in Caucasian women. Cases of such(More)
Oocyte retrieval in a stimulated in-vitro fertilization treatment cycle was unsuccessful when inadvertently carried out 12 h after the administration of human chorionic gonadotrophin (HCG) injection. Repeat follicular aspiration at 36 h post-HCG injection recovered 20 oocytes, out of which 16 metaphase-II eggs were subjected to intracytoplasmic sperm(More)
Purpose: Our purpose was to determine if embryo cell stage at the time of intrauterine transfer correlates with pregnancy rate in patients treated with intracytoplasmic sperm injection (ICSI). Methods: We conducted a retrospective analysis of 455 embryo transfer cycles following ICSI and 304 conventional in vitro fertilization (IVF) and embryo transfer(More)
Four distinct studies were carried out using two data sets of percutaneous epididymal sperm aspiration (PESA) and intracytoplasmic sperm injection (ICSI) procedures performed from March 1993 to January 1997. In study A, an analysis of 181 ICSI treatment cycles following PESA revealed a successful epididymal sperm retrieval rate of 83%. It confirmed that(More)
Percutaneous epididymal sperm aspiration (PESA) and intracytoplasmic sperm injection (ICSI) were carried out in patients with congenital bilateral absence of the vas deferens (CBAVD) and men with failed reversal of vasectomy (FRV). PESA was successful in 55 out of 62 patients with CBAVD (89%) and in 57 out of 60 men with FRV (95%). The fertilization rates(More)
