Ivf, Frozen Embryo Transfer (FET)
Comparison of Pregnancy Rates in Modified Natural Frozen Embryo Transfer (FET) Cycle After Luteal Support with GnRH Agonist Versus Progesterone
Background: The capability to transfer frozen embryos reduces embryo loss following in vitro fertilization (IVF) and results in higher pregnancy rates compared to a single IVF cycle.

Endometriosis, Adenomyosis
Benefit of GnRH Agonist Before Frozen Embryo Transfer in Patients With Endometriosis and/or Adenomyosis
Women suffering from endometriosis and/or adenomyosis may also suffer from infertility. GnRH agonist injection could improve implantation and therefore increase the pregnancy rate in these patients.

Reproductive Issues
Impact of Serum Progesterone Levels on Embryo Transfer Day on Clinical Pregnancy
Hypotheses: We hypothesize that serum progesterone levels on the day of embryo transfer in HRT-FET cycles are positively associated with clinical pregnancy rates.
