Micronized natural progesterone (Seidigestan®) vs GnRH antagonists for preventing the LH surge during controlled ovarian stimulation (PRO_NAT study): study protocol of a randomized clinical trial
Frontiers in endocrinology ·doi:10.3389/fendo.2024.1350154

INTRODUCTION: Progesterone-primed cycles effectively suppress the pituitary LH surge during ovarian stimulation in oocyte donors and in the infertile population. Particularly in oocyte donors, the use of synthetic progesterone (progestins) …

Luteal phase stimulation versus follicular phase stimulation in poor ovarian responders: results of a randomized controlled trial
Reproductive biology and endocrinology : RB&E ·doi:10.1186/s12958-020-00570-7

BACKGROUND: In young women with poor ovarian response, luteal-phase ovarian stimulation (LPOS) is a potential method for collecting competent oocytes. The aim of this study was to assess the efficacy of LPOS compared with follicular phase o…
