Which sign indicates uterine development early in puberty?

• A. Adult-type hair
• B. Breast enlargement
• C. Physiologic leukorrhea
• D. Menarche

Answer: (C)

Rising estrogen during puberty drives maturation of the uterus and the lower genital tract, and physiologic leukorrhea is a direct sign of that process. This normal vaginal discharge results from estrogen-stimulated maturation of the vaginal epithelium and cervical mucus production, indicating that the reproductive tract is becoming functionally mature. Breast enlargement reflects estrogen’s effect on breast tissue, not uterine development per se. Adult-type body hair arises mainly from androgen effects and isn’t a marker of uterine maturation. Menarche marks the first menstrual period and comes after initial uterine and reproductive tract development has progressed, so it’s a later sign.
