Absence of ovulation stigma in the conception cycle

Summary
Ovulation stigmata, including the luteinized unruptured follicle, are infrequently observed during laparoscopy, even in patients who conceive. Further diagnostic methods are needed for ovum retention syndrome.
Area of Science:
- Reproductive Endocrinology
- Gynecologic Surgery
Background:
- The luteinized unruptured follicle (LUF) is a debated phenomenon in reproductive medicine.
- Ovulation stigmata are visual indicators of follicular rupture observed during laparoscopic procedures.
Purpose of the Study:
- To determine the incidence of ovulation stigmata and LUF in women who conceived during their laparoscopy cycle.
- To evaluate the reliability of laparoscopic findings for diagnosing ovulation and ovum retention.
Main Methods:
- Laparoscopic visualization of ovaries in six patients who conceived during the cycle of surgery.
- Ovarian assessment was performed at different time points after the basal body temperature (BBT) dip.
Main Results:
- Only 33.3% of patients showed ovulation stigmata when ovaries were visualized 2-7 days post-BBT dip.
- 66.6% of patients who conceived showed no ovulation stigmata when ovaries were visualized 10-12 days post-BBT dip, despite proven ovulation.
- The laparoscopic appearance of LUF may not indicate a trapped ovum.
Conclusions:
- Laparoscopic findings of LUF are unreliable for diagnosing ovum retention.
- Ovulation stigmata are not consistently present even after confirmed conception.
- Alternative diagnostic procedures are necessary for accurate diagnosis of ovum retention syndrome.
