Progestin-primed ovarian stimulation for oocyte cryopreservation in patients with nonmedical indications: a case-control study. [PDF]

Reprod Biol Endocrinol
The PPOS (Progestin Primed Ovarian Stimulation) protocol has been evaluated and has proved its effectiveness in preventing the LH (luteinizing hormone) surge. This protocol is often used for cryopreservation for social reasons because it is simpler and more cost-effective.

Comparing blastocyst euploid rates between the progestin-primed and gonadotrophin-releasing hormone antagonist protocols in aneuploidy genetic testing: a randomised trial protocol

BMJ Open
Introduction Progestin can inhibit the pituitary luteinising hormone (LH) surge during ovarian stimulation for in vitro fertilisation (IVF) and studies show progestin-primed ovarian stimulation (PPOS) is effective in blocking the LH surge in IVF.
