Not Applicable

• Conditions: Endometrioma

• Lead Sponsor: Charles University, Czech Republic

Brief Summary

Ovarian endometriosis (endometrioma) can be a cause of subfertility. According to European Society of Human Reproduction and Embryology (ESHRE) guidelines, surgery for endometrioma is recommended when an endometrioma is more than 3 cm in diameter because this management is associated with better spontaneous conception rates. Nevertheless, surgery can also be potentially associated with a risk of destruction of functional ovarian tissue and reduction in ovarian reserve.

Anti-müllerian hormone (AMH) is a member of the Transforming Growth Factor beta family and is expressed by the small (\<8 mm) pre-antral and early antral follicles. The AMH level reflects the size of the primordial follicle pool, and may be the best biochemical marker of ovarian function across an array of clinical situations Its level in serum is almost stable between 20 and 35 years of the woman´s life, unless using hormonal contraception and / or they suffer with Polycystic ovarian syndrome (PCOS). The level of AMH is also a useful indicator for the prediction chances of success of spontaneous or assisted conceptions. However, there paucity of data regarding changes in serum levels of AMH following surgery for endometrioma.

An alternative way for estimating ovarian reserve is quantifying ovarian mass with using standard 3D transvaginal ultrasound calculation (OVM) and assessment of antral follicular count.

The gold standard of endometrioma surgery is laparoscopic excision with suture or gentle coagulation of the rest of ovary or by the use of laparoscopic treatment with argon plasma energy.
