Luteal phase support for women trying to conceive by intrauterine insemination or sexual intercourse
BACKGROUND: Ovulation induction may impact endometrial receptivity due to insufficient progesterone secretion. Low progesterone is associated with poor pregnancy outcomes. OBJECTIVES: To assess the effectiveness and safety of luteal phase …
