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.
The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. The female needs a male to fertilize her egg, even though it is she who carries offspring through pregnancy and childbirth.When the sperm fertilizes, or meets, the egg, this fertilized egg is called the zygote. female's internal reproductive organs are the vagina, uterus, fallopian tubes, and ovaries. The vagina is a muscular, hollow tube that extends from the vaginal opening to the uterus. The vagina is about 3 to 5 inches (8 to 12 centimeters) long in a grown woman. Because it has muscular walls it can expand and contract.
