Drug-free in-vitro activation of follicles and fresh tissue autotransplantation as a therapeutic option in patients with primary ovarian insufficiency

Research question: Could in-vitro action of follicles and fresh tissue autotransplantation without tissue culture (drug-free IVA) be useful in patients with primary ovarian insufficiency (POI)? Design: Prospective observational cohort study in a tertiary university hospital. Drug-Free IVA was carried out in 14 women with POI with a median age of 33 years (29-36 years), median length of amenorrhoea of 1.5 years (1-11 years), median FSH levels 69.2 mIU/ml (36.9-82.8 mIU/ml) and anti-Mullerian hormone of 0.02 ng/ml (0.01-0.1 ng/ml). The surgical procedure included laparoscopic removal of ovarian cortex, fragmentation of tissue and autografting. Human menopausal gonadotrophin (HMG) was started immediately after surgery. Results: Follicle development was detected in seven out of the 14 patients, and five women achieved successful oocyte retrieval. In six women, HCG was administered in 10 cycles. Six embryo transfers were carried out in five women resulting in four pregnancies; a clinical pregnancy rate of four in seven oocyte retrievals and four in six embryo transfers. Conclusions: Drug-free IVA could be a useful therapeutic option for patients with POI, leading to successful IVF outcomes.
