In Vitro Activation of Dormant Follicles for Patients With Primary Ovarian Insufficiency

Not Recruiting

Trial ID: NCT02322060

Purpose

In this study, the investigators used the newly developed technique i.e. in vitro activation of dormant follicles (IVA) to promote ovarian follicle growth much more efficiently than natural, in vivo process for women with Primary Ovarian Insufficiency (POI).Firstly, the investigators remove one ovary under laparoscopic surgery. Then, we dissect ovarian cortex from the ovarian medulla. The ovarian cortex is cut into small cubes and cultured with medium containing drugs to activate dormant follicles. After 2 days of culture, the ovarian cubes are transplanted mainly beneath the membrane of Fallopian tubes under laparoscopic surgery. The ovarian cortex could be cryopreserve for future re-transplantation and in some cases, for convenience to arrange second surgery. Once frozen, the ovary can be preserved semipermanently. After transplantation, patients receive ultrasound monitoring together with measurement of serum hormone levels for 10-12 months. If growing follicles are detected, follicle growth is stimulated by injection of hormones (gonadotropins). Using the same "ovum pick up" approach used in IVF (in vitro fertilization), we pick up oocytes from the follicles and fertilize them. Fertilized eggs are cultured and then cryopreserved for future embryo transfer. Currently, we recurit patients diagnosed with POI, or Ovarian resistance syndrome (ORS). The procedure can also be: Only superficial cut of the ovarian cortex by laparoscopy or laparotomy, without taking ovary outside or cultured with medium.
