Which human hormone is often referred to as the 'pregnancy hormone' because it is essential for maintaining the uterine lining during gestation?

💡 Solution & Explanation

Progesterone is often termed the pregnancy hormone because it maintains the functional uterine lining and supports gestation while inhibiting further ovulation during pregnancy. Oxytocin and prolactin regulate uterine contractions during childbirth and milk synthesis rather than early endometrial maintenance. Human physiology and endocrinology are core topics in biology.
