OBJECTIVE To evaluate the efficiency of oocyte donation cycles using egg "cryo-banking." DESIGN Study conditions for vitrified/warmed oocytes for 20 non-autologous recipients (from 10 donors) were set prospectively, and outcomes of it were later compared retrospectively to nine fresh donations cycles. SETTING Private assisted reproductive technology(More)
Zygotes and 2- to 5-cell human embryos were frozen in 1,2-propanediol and sucrose; results of the first 50 cycles (45 patients) are presented. A total of 41 zygotes (17 attempts at thawing) were thawed, resulting in six singleton clinical pregnancies (15% per embryo; 35% per cycle), of which three delivered, one aborted, and two are ongoing. Fifty-seven(More)
In two separate prospectively randomized trials, intracytoplasmic sperm injection (ICSI) cycles were studied in a controlled manner to monitor the effects of either bovine oviductal epithelial cell co-culture (n = 119) or assisted hatching by zona drilling (n = 100). In the first study, immediately following ICSI, all eggs were placed directly either onto(More)
The effects of cryopreservation on human zygotes at various stages between the appearance of pronuclei and their close association were investigated. Pronuclear zygotes (n = 233) from 101 patients were frozen using propanediol 21-35 h following egg collection. The incidence of implantation of thawed pronuclear zygotes frozen 29-35 h following oocyte(More)
Body mass index (BMI) has been demonstrated to affect female fertility; however, little information is available on the impact of BMI on male fertility or semen parameters. Therefore, the study objective was to determine the relationship between BMI and semen parameters, including sperm chromatin integrity. We analyzed data on semen samples from 520 men who(More)
The effect of low dose immunosuppression with methylprednisolone during the first 4 days after oocyte retrieval on potential immune cell invasion of partially zona dissected embryos in utero was investigated in alternate in vitro fertilization patients (n = 32). The incidence of pregnancy was significantly higher in patients receiving methylprednisolone (7(More)
Arrhenoblastoma is a rare complication of pregnancy. A case of fatal nonvirilizing arrhenoblastoma in a pregnant adolescent, the third such case to appear in the literature, is discussed. Fifteen cases of arrhenoblastoma in pregnancy that have appeared in the recent literature are reviewed; 87% of these tumors were virilizing. When virilization is absent(More)
OBJECTIVE To determine the relationship between platelet-activating factor acetylhydrolase (PAFah) content in semen and sperm motility. DESIGN The PAFah levels in semen were measured and correlated with sperm motility. SETTING Clinical laboratory in a private assistant reproductive technology clinic. PATIENT(S) Three hundred and twelve men seeking(More)
