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.

A recent randomized controlled trial compares ovarian stimulation protocols (standard vs. tamoxifen vs. letrozole) for freezing oocytes or embryos used in women diagnosed with breast cancer.

A recent well-designed American trial asked women with PCOS and obesity to take either placebo or GLP-1 agonist. 1/3 of participants were African-American and 2/3 were Caucasian. Most women had a goal of pregnancy.
After 32 weeks, the women were compared for differences in weight loss, menses, and hormones.

The differences were significant in many ways.
