A technique for transplantation of ovarian cortical strips to the forearm.
Overview
abstract
OBJECTIVE: To describe a forearm heterotopic ovarian transplantation technique. DESIGN: Case study. SETTING: Academic medical center. PATIENT(S): One patient with stage IIIB squamous cell cervical carcinoma and one patient with recurrent benign ovarian cysts. INTERVENTION(S): Preparation of thin ovarian cortical slices and transplantation under the skin of the forearm. MAIN OUTCOME MEASURE(S): Follicular development and oocyte retrieval; cyclical estradiol (E(2)) and progesterone (P(4)) production; restoration of serum follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels to reproductive age range. RESULT(S): Both patients were menopausal immediately after oophorectomy. The first patient developed a dominant follicle 10 weeks after transplantation, and her gonadotropin levels decreased to nonmenopausal levels. Percutaneous aspiration of ovarian follicles yielded a metaphase I (M-I) oocyte that was matured to metaphase II (M-II). The first patient's graft was functional for at least 21 months. In the second patient, ovarian follicle development was detected 6 months after transplantation, and periodic menstruation occurred thereafter. Spontaneous ovulation was confirmed by a midluteal increase in her P(4) levels. Menstruation and follicle development continued for more than 2 years after the transplant. CONCLUSION(S): Heterotopic transplantation of ovarian tissue to the forearm is a simple and promising technique to restore ovarian function in women who become menopausal due to chemotherapy, surgery, or radiation.
