Luteal phase support for assisted reproduction cycles [PDF]

Cochrane Database of Systematic Reviews, 2011
Progesterone prepares the endometrium for pregnancy by stimulating proliferation in response to human chorionic gonadotropin (hCG), which is produced by the corpus luteum. This occurs in the luteal phase of the menstrual cycle. In assisted reproduction techniques (ART) the progesterone or hCG levels, or both, are low and the natural process is ...

#369 : A Case of Luteal Phase Deficiency (LPD) and Polycystic Ovarian Syndrome (PCOS). When Routine is not Enough

Fertility & Reproduction, 2023
Background and Aims: Luteal phase deficiency (LPD) is a consequence of the inability of the corpus luteum (CL) to produce an adequate level of progesterone. This manifests clinically as a short menstrual cycle and infertility.
