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.
These sperm are looking for an ovum (or egg) to fertilise. When a female is born she carries thousands of ova or eggs ready to use when she becomes adult. These are the female 'seeds' that, along with sperm, contribute to creating a new life. Once a month, the female releases an ovum (one egg) . If an ovum has been released, a sperm can unite with it, fertilise it and make the first cell of a new baby. Once one sperm has fertilised the ovum, no other sperm can get in. For the sperm it's like a race and there is only one winner.
