Which hormones are produced by the bovine endometrium?

• A. Prolactin
• B. Estrogen
• C. Prolactin and Estrogen
• D. Progesterone

Answer: (C)

Some tissues in the reproductive tract can make hormones themselves, providing local signals that help regulate function. The bovine endometrium can synthesize both estrogen and prolactin locally. Estrogen produced in the uterine lining supports its own secretory activity and tissue remodeling, contributing to a receptive environment for embryo support. Prolactin has a role as a locally produced factor in the uterus that can influence uterine and mammary-associated processes. Progesterone, however, is primarily produced by the corpus luteum and later by the placenta, not by the endometrium itself. Because the endometrium is capable of producing estrogen and prolactin, that combination is the best fit.
