After fertilization, most of the leftover sperm are blocked from entering the already fertilized egg by a protective barrier. The sperm cells that do make it through generally don't contribute to the genetic material of the embryo.

Only if you've gotten pregnant. The only thing that controls your period is ovulation (which produces hormones) or birth control that 'mimics' hormones.

Can a woman get pregnant before she begins ovulating and is there less of a chance?

The only time a woman can get pregnant is when she ovulates. The egg can be fertilised for about 36 hours. However sperm has been known to live in the vaginal tract/womb/fallopian tubes for up to 5 days, so while a woman can only get pregnant when she ovulates ie when an egg is available for the sperm to fertilise, the length of time that sperm can live for must also be considered when timing intercourse.


What is happens when the sperm ducts have been cut and tyed?

The sperms that are produced by the male reproductive organ cannot be trasported to the penis via the sperm duct to enter the female's body, hence fertilisation cannot occur


Science words that start with Z?

Zygote, which is a word from biology and is basically a egg that has been fertilised by a sperm cell, so the very early stages of a baby in the womb. Hope this helps :)


Why do womens have period?

Each month, from the age of about 12, a woman releases one egg each month. If this egg is fertilised by sperm during sex, a baby is made. If it isn't fertilised, it starts to break down and the body needs to get rid of it. Also, during the month, the lining of the woman's uterus/womb starts to build up and thicken so that if the egg is fertilised it will be able to implant into the lining and grow. If the egg is not fertilised, the body also needs to get rid of this built-up lining. So, once the egg has been released, and not fertilised it will start to break down and the remains leave the uterus through the cervix and out of the vagina. As the lining of the uterus starts to break down and detach, blood vessels are ruptured and this is where the blood comes from.


Can you have a menstrual cycle after you conceive?

No, because the egg has been fertilised and the womb lining is needed for the baby, so will not break down. Instead, when you period is due, you may have spotting which is when the fertilised egg implants in the womb lining


Is the ovum released after fertilisation or before during menstruation?

The ovum (egg) is released before a period and it travels down the Fallopian tube into the womb. A few days later, if it has not been fertilised by a sperm, then the womb will shed its lining, and will also shed the ovum (egg). This shedding of the womb is a woman's period.
