A study compared fertility and sexual markers in obese men with low testosterone and erectile dysfunction who took liraglutide, uFSH + HCG, or testosterone. These men were separated into three groups based on their plans for parenthood; results showed impressive improvements on the GLP-1 agonist liraglutide.

A recent study compared GnRH antagonists in egg donor ovarian stimulation cycles. The first drug is a newer agent, elagolix (Orilissa), that is taken as a tablet at night. The older drug is an injectable agent called ganirelix (Fyremadel). How did Orilissa stack up in terms of eggs retrieved and embryos formed vs. ganirelix? Were there adverse events, like ovarian hyperstimulation or early LH surge? Results explored in this episode and what they mean for upcoming egg donor cycles.

Does vaginal progesterone prevent miscarriages after early pregnancy bleeding? The research world has yet to agree, but a recently published Australian study (aka "the STOP trial") attempted to tackle this question.
After seven years of recruiting ~300 women, the STOP trial was stopped prematurely based on early results.
Hurdles with study execution plus thinly-disguised jabs at other research made for an interesting paper.
