Membrane progestin receptor alpha mediates progestin-induced sperm hypermotility and increased fertilization success in southern flounder (Paralichthys lethostigma)

, 2014
Progestin hormones stimulate sperm motility in teleosts but their mechanisms of action remain unclear. Preliminary results suggest that progestin upregulation of sperm motility in southern flounder and several other marine species is mediated through a ...

Norethisterone-Associated Decidual Cast Expulsion Mimicking an Acute Gynecologic Emergency: A Case Report. [PDF]

Clin Case Rep
ABSTRACT Decidual cast is a rare benign condition that may mimic acute gynecologic emergencies. It should be suspected in patients with severe colicky pain followed by sudden relief after tissue expulsion, especially with progestin use such as norethisterone. Accurate diagnosis and histopathology prevent unnecessary surgery.

Membranous dysmenorrhea and decidual casts: A scoping review

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Membranous dysmenorrhea, characterized by the expulsion of intact endometrial tissue rather than gradual dissolution during menstruation, occasionally presents as a decidual cast—a complete triangular mold of the uterine cavity. This poorly understood condition is likely underdiagnosed.
