The ovaries are endocrine glands which release two hormones important for sexual development: estrogen and which other? (A) Thyroid-stimulating hormone, (B) progesterone, (C) insulin, (D) growth hormone.

This question is asking us to recall what hormones the ovaries release that are important for sexual development. To answer this question, let’s review what we know about the ovaries and their functions as endocrine glands.

As endocrine glands, the ovaries release hormones that are important for the development of secondary sex characteristics of biological females and reproduction. One of the most well-known hormones released by the ovaries is estrogen. Estrogen is a sex hormone produced during puberty, which is a period of time in where secondary sex characteristics begin to develop, such as facial hair for men and breasts for women.

Estrogen is also important for regulating the menstrual cycle, which typically lasts 28 days. This cycle releases a mature egg that can be fertilized and prepares the female body for a potential pregnancy. In response to follicle-stimulating hormone, or FSH, which is secreted by the pituitary gland, the ovaries will begin to produce estrogen that will help to build the lining of the uterus. Once a mature egg is released from the ovaries, a second hormone is produced, which is called progesterone.

Progesterone helps maintain the uterine lining in case a fertilized egg implants and begins to develop in the uterus. If the fertilized egg implants, then progesterone prevents the uterus from contracting. It also increases the blood flow to the uterus.

So estrogen and progesterone are produced by the ovaries and influence the sexual development of the female body. With this information, we’re able to correctly answer our question. The two hormones important for sexual development that are released by the ovaries are estrogen and progesterone.
