Which statement correctly describes pregnancy hormones according to the material?

• A. Progesterone & Estrogen are not related to pregnancy
• B. Progesterone & Estrogen are pregnancy hormones
• C. Estrogen alone is a pregnancy hormone
• D. Progesterone alone is a pregnancy hormone

Answer: (B)

Both progesterone and estrogen are pregnancy hormones that work together to sustain gestation. Progesterone helps maintain the uterine lining and keeps the uterus from contracting prematurely, creating a stable environment for the developing embryo. Estrogen promotes growth of the uterus and placenta, increases uterine blood flow, and prepares the breasts for lactation. As pregnancy progresses, levels rise and are produced by the ovaries early on and by the placenta later, reflecting a coordinated hormonal action essential for implantation, placental development, and fetal growth. Saying that both are pregnancy hormones best captures their combined role; claiming only one of them is involved or that they aren’t related to pregnancy misses how they function together during gestation.
