- 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.arrow_forwardWhat leads to teenage pregnancy?arrow_forwardA 22-year-old woman consumes large quantities of alcohol at a party and loses consciousness.
