No. Turhan et al., A COMPARATIVE-STUDY OF 3 OVULATION INDUCTION PROTOCOLS IN POLYCYSTIC OVARIAN DISEASE PATIENTS IN AN INVITRO FERTILIZATION EMBRYO TRANSFER PROGRAM, Journal of assisted reproduction and genetics, 10(1), 1993, pp. 15-20
Purpose: This study compares the results of three ovulation induction
protocols in polycystic ovarian disease (PCOD) patients undergoing an
in vitro fertilization-embryo transfer (IVF-ET) program. A total of 85
cycles was studied. The patients were treated with clomiphene citrate
(CC) plus human menopausal gonadotropin (hMG) (CC/hMG group), with pu
rified menofollitropin (pFSH) plus hMG (pFSH/hMG group), and with pFSH
/hMG plus gonadotropin releasing hormone analogue (GnRH-a) (analogue g
roup). In the analogue group the suppression of luteinizing hormone (L
H) with GnRH-a decreased the number of follicles <12 mm on the day of
human chorionic gonadotropin (hCG) administration and the number and p
ercentage of immature oocytes retrieved and increased the percentage o
f mature oocytes retrieved. Results: However, fertilization rates of o
ocytes, cleaved embryo rates, pregnancy rates following replacement, a
nd pregnancy outcomes were not different. Conclusion: Although the sup
pression of the hypothalamic-pituitary-ovarian axis with GnRH-a in PCO
D patients improved follicular synchrony and oocyte maturity, none of
the ovulation induction protocols was superior to the others with resp
ect to pregnancy rates and pregnancy outcomes.
