Question

Which statement explains how a 5-year-old female could present with pubic hair growth?

Estrogen is released prematurely by the anterior pituitary.

Luteinizing hormone (LH) is released in large quantities from the ovaries.

Gonadotropin-releasing hormone (GnRH) is released prematurely by the hypothalamus.

Follicle-stimulating hormone (FSH) is released in large quantities from the hypothalamus.

Answer 1

Pubic hair growth in a 5-year-old female can be explained by the premature release of estrogen by the anterior pituitary gland.

Step-by-step explanation:

Puberty in girls is initiated by the hypothalamus sending signals to the pituitary gland to secrete hormones that target the ovaries. This includes luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which stimulate the ovaries to produce estrogen. Estrogen is responsible for promoting growth and physical changes during puberty, such as breast development and the growth of pubic hair. Therefore, the statement that explains how a 5-year-old female could present with pubic hair growth is that estrogen is released prematurely by the anterior pituitary.
