Which event is considered the hallmark of late puberty in young girls?

• A. Breast enlargement
• B. Physiologic leukorrhea
• C. First menstrual period
• D. Adult type sexual hair

Answer: (C)

The main idea here is recognizing the sequence of pubertal changes in girls and identifying the milestone that signals mature reproductive capability. The first menstrual period, or menarche, is the event that marks late puberty and the transition toward reproductive maturity. It typically follows earlier changes like breast development (thelarche) and the onset of pubic hair, and while vaginal discharge can occur during puberty, it is not the defining hallmark of late puberty. Menarche indicates that the reproductive system has reached a level of maturity where ovulatory potential begins, making it the best answer.
