(1) Male and female embryos exhibit few anatomical differences until after the second month of development. Several common sex hormones continue to function into adulthood, including FSH and LH. Describe where these hormones come from and what their role is in adult males and females, with reference to the reproductive structures.

(2) Pregnancy can be detected several days post-implantation, based on a hormone level test. What is the hormone that is tested for in pregnancy, and what is its role? How is the test administered, and who may perform it?

Solution Preview

Both of these hormones are referred to as gonadotropins because they stimulate the gonads: testes in males and ovaries in females. These hormones are vital to reproduction.

FSH stands for follicle stimulating hormone. This hormone is what stimulates the ovarian follicles of the ovaries to mature in women and it is secreted from the gondatrophs, which are cells in the anterior pituitary gland. In males, this hormone is important in sperm production.

LH stands for luteinizing hormone. This hormone is also secreted by the gonadtrophs and is responsible stimulating the secretion of sex steroids, testosterone and ...

Solution Summary

This solution contains information on hormones released by the gonadotropins, the names of the hormones, the function of these hormones, and how to test for hCG.

organizing effects or the activating effects of hormones

Can you help me with the following:

Try this exercise: Hold out your right hand, place fingers together, and compare the length of your index (first) finger and ring (third) finger.

The hormone "testosterone" is linked with masculine traits.

The amount of testosterone exposed to in the womb affects finger length. The higher the testosterone exposure, the longer the ring finger.

Women's index and ring fingers are almost equal because they have been exposed to less testosterone.

If women have longer ring fingers, then they have more masculine tendencies.

In men, the ring finger is longer because they have higher testosterone levels.

If men have ring fingers equal in length to their index fingers, or shorter, they have less masculine tendencies because they have been exposed to slightly less testosterone.

Would you say this is a result of the organizing effects or the activating effects of hormones?
Please provide other examples where either the organizing effects or the activating effects show a marked physical difference between males and females? (other than the obvious primary and secondary sexual characteristics) Please provide examples
