Abstract: | The outcome of in-vitro fertilization and embryo transfer (IVFET)was compared in 76 patients with polycystic ovaries (PCO) diagnosedon pre-treatment ultrasound scan, and 76 control patients whohad normal ovaries and were matched for age, cause of infertilityand stimulation regimen. Despite receiving significantly lesshuman menopausal gonadotrophin (HMG), patients with PCO, ascompared with controls, had significantly higher serum oestradiollevels on the day of human chronic gonadotrophin administration(5940 ± 255 versus 4370 ± 240 pmol/1, P < 0.001),developed more follicles (14.9 ± 0.7 versus 9.8 ±0.6, P < 0.001) and produced more oocytes (9.3 ± 0.6versus 6.8 ± 0.5, P = 0.003). However, fertilizationrates were reduced in the PCO patients (52.8 ± 3.4% versus66.1 ± 3.4%, P = 0.007). There was no significant differencein cleavage rates. The pregnancy rate/embryo transfer was 25.4%in the PCO group and 23.0% in the group with normal ovaries.There were three high order multiple pregnancies in the PCOgroup compared with none in the group with normal ovaries. Ofthe PCO patients, 10.5% developed moderate/severe ovarian hyperstimulationsyndrome (OHSS) compared with none of the controls (P = 0.006).Patients with and without PCO undergoing IVF have comparablepregnancy and livebirth rates. However, it is important to diagnosePCO before ovarian stimulation is initiated as these patientsare more likely to develop moderate or severe OHSS following1VFET. |
