Fertility
pregnancies per transfer
The chance of a pregnancy, a live birth, an ovulation, or a usable sperm count. A blood testosterone reading is a different measure.
A trial can count a heartbeat after embryo transfer, a natural pregnancy, a return of bleeding, ovarian volume, or the share of sperm with a normal shape. The object is the event or the gamete, not a hormone panel.
Also called pregnancy, live birth, ovulation, sperm morphology, IVF pregnancy.

GLP-1 receptor agonist→Fertility
Higher GLP-1 receptor agonist increases Fertility.
In 28 infertile obese women with PCOS, twelve weeks of low-dose liraglutide added to metformin, then stopped for four weeks, was followed by more IVF pregnancies per embryo transfer than metformin alone: 85.7 percent versus 28.6 percent (Salamun 2018). The file is small and stacked.
