How long does sperm live outside of the human body without help?
Step by step
Solved in 2 steps
- 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.Why sperms are produced in large numbers?If spermatogenesis is normal and all cells survive, how many sperm cells will be formed from 100 spermatogonia?

Four partsexplain the organisation of the flagella of spermGross Anatomy of the Human Male and Female Reproductive System a) Assume that a couple has just consummated the sex act and that the sperm have been deposited in the vagina. Trace the pathway of the sperm through the female reproductive tract. b) Define ovulation. c)The testis is divided into a number of lobes by connective tissue. Each of these lobes contains one to four_______ which converge to empty sperm into another set of tubules called the_______
