A proposed shortfall in progesterone production by the corpus luteum after ovulation, linked to infertility and early pregnancy loss. Blood testing measures luteal-phase progesterone.
Our comprehensive check-up screens for insufficiency of the luteal corpus and hundreds of other conditions.
Progesterone is a hormone produced after ovulation and during pregnancy. It plays a key role in regulating the menstrual cycle, preparing the uterus for pregnancy, and supporting early pregnancy. In non-pregnant women, progesterone drops trigger menstruation.
Estradiol (E2)The primary active estrogen in the body. Estradiol is produced in the gonads (ovaries and testes) and in adipose tissue. It plays a central role in bone metabolism, cardiovascular protection, brain function, mood regulation, and reproductive health. Levels vary with the menstrual cycle and decline significantly during menopause. Low levels are associated with reduced bone density, mood disturbances, and impaired fertility. Elevated levels may indicate hormonal imbalance or increased aromatase activity.
