Answer 1

Answer:

here is Ur answer mate

Explanation:

Sperm are the male 'seeds' that contribute to starting a new life - living sperm look a bit like tadpoles (under a microscope). They form in the testes.

sexualityWhen sperm are ejaculated (say ee-jak-u-lay-ted) from the penis during sexual intercourse, they swim up the vagina (vaj-eye-na), through the cervix (sir-vix), into the uterus (you-ter-us) and then into the fallopian (fal-o-pe-an) tubes of the female. 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, create a new life.

sexualityOnce a month, the female releases an ovum (one egg) or sometimes two (ova) .

If an ovum has been released, and the couple have sex, 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.

Ovulation and menstruation [periods] can begin as early as 9 years for some females, but usually start at a few years later for most girls. Have a look at this topic on Periods. A female is able to get pregnant once she starts ovulating. When a girl starts having periods it is the sign that she has started ovulating. Young girls are not physically and emotionally capable of dealing with pregnancy and being a mother until they become young adults.
