African-Americans or those with a family history of colon cancer should schedule their first colonoscopy at age 45. If your initial colonoscopy is clear and there are no polyps detected, you should schedule your next colonoscopy in 10 years.
âRemember, women are born with all the eggs they are ever going to have, and they donât make any new eggs during their lifetime. Women are born with approximately two million eggs in their ovaries, but about eleven thousand of them die every month prior to puberty.
Reproduction can be defined as the process by which an organism continues its species. In the human reproductive process, two kinds of sex cells (gametes), are involved: the male gamete (sperm), and the female gamete (egg or ovum).These two gametes meet within the female's uterine tubes located one on each side of the upper pelvic cavity, and begin to create a new individual.exual reproduction cannot happen without the sexual organs called gonads. Both sexes have gonads: in females, the gonads are the ovaries. The female gonads produce female gametes (eggs); the male gonads produce male gametes (sperm). After an egg is fertilized by the sperm, the fertilized egg is called the zygote.
