Conception is an incredible process. The male sperm and the female egg have to come together in the right place and at exactly the right time and that's not easy.
To give yourself the best chance of conceiving, it's really important that you understand what happens when and how the male and female reproductive systems work.
Every month (in most cases) the female produces an egg from one of her ovaries. A woman has 2 ovaries which lie one on each side of the womb (uterus). The ovaries store the eggs in little sacs called follicles. Once the egg is released from the ovary, fine hairs at the end of one of the fallopian tubes pick it up and kind of wave it into the fallopian tube. The egg then goes down the fallopian tube into the womb. If the egg has been fertilised, it implants itself into the lining of the uterus or the endometrium. During each cycle the endometrium thickens so that it is ready to receive a fertilised egg. If there is no fertilised egg, the endometrium/womb-lining breaks down and is shed from the body at menstruation, when a woman has a period.
Male semen contains millions of sperm, yet of these millions only one is needed to conceive a baby. The sperm can swim as they have to move quite a long way through the cervix, into the uterus and along the fallopian tubes. As the sperm travel, chemical changes mature them so that they become capable of fertilising an egg.
When a couple has full intercourse the man ejaculates his semen into the woman's vagina near the cervix, the entrance to the woman's womb. During most of the month,the cervix is blocked by cervical mucus (a kind of gluey, cloudy substance).A woman's cervical mucus thins out, and becomes seethrough and egg-white-like. around the time of ovulation (when an egg is released from one of the ovaries) to make it easier for sperm to pass through.
The woman's egg and the man's sperm usually meet in the fallopian tube. One single sperm penetrates the egg and fertilises it.The fertilised egg then travels into the womb where it implants into the womb lining. Once the egg has implanted, the embryo starts to grow and is sustained by hormones, until the placenta develops and takes over to nourish the growing baby. some time around nine months after conception, the developing baby will be born.
