Which of the following is NOT a typical sign of female sexual maturation?

During female sexual maturation, several physiological changes occur that are characteristic of puberty. Menstruation, breast development, and pubic hair growth are all typical indicators of this process.

Menstruation marks the onset of reproductive capability and signifies that the ovaries have begun to release eggs. Breast development indicates the hormonal changes that take place during puberty, as estrogen causes the breast tissue to grow and mature. Pubic hair growth is also a physical manifestation of the increased androgen levels in girls during puberty.

In contrast, a significant change in voice, which is commonly associated with male puberty due to an increase in testosterone, does not occur in females to the same extent. While girls may experience some subtle changes in their voice during puberty, these are not as pronounced or characteristic as the changes observed in males. This absence of a prominent voice change aligns with why it is identified as not being a typical sign of female sexual maturation.
