INTRODUCTION
Premature ovarian insufficiency (POI) is characterised by diminished ovarian reserve, poor response to ovarian stimulation, and low chance of spontaneous conception. In vitro activation (IVA) has emerged as a potential treatment option for selected patients with residual ovarian activity.
METHODS
A 32-year-old woman presented in Alhaya with a 4-year history of primary infertility and 1 year amenorrhea. She had severely diminished ovarian reserve, with anti-Müllerian hormone (AMH) <0.07pmol/L, elevated follicle-stimulating hormone (FSH) of 41.2IU/L, and absent antral follicle count (AFC) on ultrasound. She was diagnosed with POI and underwent pre-IVA estrogen optimisation.


Bilateral IVA surgery was performed in July 2025
RESULTS
Follow-up demonstrated fluctuating hormonal profiles and a single AFC in August 2025. She underwent IVF stimulation; however, despite 16 days of stimulation, there was no follicular growth and IVF was abandoned. After being lost to follow-up, she experienced her first spontaneous natural menses in January 2026 and conceived naturally approximately 7 months after IVA. pregnancy was confirmed at 9 weeks’ gestation (REDD 4.12.2026).
CONCLUSIONS
This case highlights the potential long-term effect of IVA in activating dormant primordial follicles. Because it takes approximately 6 months for follicles to develop from the primordial to the antral stage, patients should be followed-up long-term after IVA. Nevertheless, this case highlights the need to clarify patient selection criteria for spontaneous pregnancy after IVA surgery.
