A comparative, randomized study of three different progesterone support of the luteal phase following IVF/ET program
This study compared progesterone i.m., hCG, progesterone vaginal cream, and no support in IVF patients, finding all increased luteal progesterone but no significant pregnancy rate differences.

This randomized study compared luteal phase support methods after IVF/ET in 176 women: intramuscular progesterone (50 mg/day), hCG injections (2000 IU every three days), vaginal progesterone cream (100 mg/day), or no supplementation. Serum progesterone and 17-β-estradiol (and the E2/P ratio) were measured across the luteal phase, and pregnancy outcomes were assessed between groups. The authors found no statistically significant differences in pregnancy rates among the groups, but all active treatments increased luteal progesterone versus controls, and vaginal cream (and intramuscular progesterone) reduced the E2/P ratio relative to controls; progesterone vaginal cream produced steadier serum progesterone levels than injections. The paper does not explicitly discuss limitations beyond the reported lack of pregnancy-rate differences. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.
