Chapter 36, Problem 33A

Summary Introduction

To explain:

Woman go through menopause and stop production of eggs and man can produce sperm throughout their life after puberty.

Introduction:

Both males and females have different reproductive systems. A male continues producing sperms throughout his life while a female stops producing eggs and goes through menopause.

Explanation of Solution

Progesterone and estrogen are formed by the ovaries. The menstruation and ovulation are regulated by these hormones. The development of hormones in the ovaries diminishes as people get older. It happens as ovaries cease eggs and a female discontinues menstruating, and menopause occurs. Male fertility is decreased during maturity, but researchers indicate that the age of a male does not have a major impact on his fertility because sperm motility is only diminished by around 1-2 percent a year.
