Summary Introduction

To review:

The reason behind low levels of LH (luteinizing hormone) and sperm count in an athlete who has been taking synthetic testosterone as a supplement.

Introduction:

The inability to get pregnanteven after a year of unprotected mating is termed as infertility. Infertility can arise in both males and females. In males, infertility is generally caused due to alow sperm count and in females, infertility may be caused due to ahormonal imbalance or aweak uterus. Male infertility constitutes about 40 percent of all the infertility cases and arises due to adecreased number of sperms. The low sperm count arises due to the low levels of LH.

A professional male athlete has been taking a synthetic testosterone supplement for several months. He and his wife have been trying to have a baby, with no success, and have decided to begin treatment for infertility. Before testing the man’s sperm, the doctor discovers that the man’s LH levels are very low. Why do you think his LH le count vels are low? Would low LH levels affect sperm production?
Hormone replacement therapy was advertised first to women in the 1990s as a way of increasing their youthfulness. Hormone replacement therapy today is usually taking pills to increase someone's estrogen or testosterone supply. Pick either estrogen or testosterone. For either one: 1) How does your chosen sex hormone work at the cellular and at the molecular level? 2) How do these hormones improve the reproductive system as a whole? 3) What are the benefits of doing hormone replacement therapy? 4) What are the harms of doing hormone replacement therapy? 5) Who would be an ideal candidate for hormone replacement therapy?
A couple living in Florida is trying to have a baby, but they are having trouble getting pregnant. The male is very light skinned yet enjoys spending as much time as possible outdoors in the sun. From the male's perspective, why might he be contributing to the trouble with getting pregnant? Excessive ultraviolet light exposure can reduce folate levels, and folate is required for normal sperm development. Excessive heat from the sunlight inhibits normal sperm production; thus, he probably does not have enough sperm. The male does not have enough melanin production to support normal sperm development. Excessive sunlight exposure can rapidly increase folate levels, which then inhibits normal sperm development. Normal sperm development occurs best in colder temperatures; thus, living in Florida he has a reduced chance of getting his partner pregnant.
