OBG · Infertility and contraception: endometrioma surgery before IVF
Sample itemA woman with infertility and a 4 cm asymptomatic ovarian endometrioma is planned for IVF. What is the concern with cystectomy before treatment?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. It may reduce ovarian reserve
Stripping an endometrioma can remove healthy ovarian cortex along with the cyst wall, reducing AMH and the number of oocytes obtained. In asymptomatic women, proceeding directly to IVF is often preferred.
Option by option
A. It prevents oocyte retrieval altogether
Oocyte retrieval remains possible, although the yield may be lower.
B. It may reduce ovarian reserve (correct)
Correct. Cystectomy can remove normal follicle-containing cortex and lower reserve.
C. It causes tubal blockage
Cystectomy does not itself block the tubes.
D. It raises the risk of ovarian cancer
Surgery does not increase ovarian cancer risk.
