Which hormones are listed as pregnancy hormones?

• A. Testosterone & LH
• B. Progesterone & Estrogen
• C. GH & IGF-1
• D. Adrenaline & Noradrenaline

Answer: (B)

Estrogen and progesterone are the hormones that support a pregnancy. Estrogen helps the uterus grow and increases blood flow to the uterine lining, creating a nourishing environment for the developing fetus. Progesterone maintains that lining and keeps the uterus from contracting prematurely, which helps prevent miscarriage and sustains the pregnancy. Together, they create a stable hormonal environment throughout gestation, with levels rising as pregnancy progresses.

The other options don’t fit as pregnancy-specific hormones. Testosterone is a male sex hormone, and LH mainly triggers ovulation rather than sustaining a pregnancy. Growth hormone (GH) and IGF-1 are important for growth in general but aren’t classified as the primary pregnancy-maintaining hormones. Adrenaline and noradrenaline are stress-related catecholamines and aren’t involved in sustaining pregnancy.
