6.Doctor, what causes my infertility? - Infertility Niche Business

When people refer to the miracle of birth it really is more than just a phrase -- it's a fact. The human reproductive system is miraculously complex. If one considers everything involved in getting pregnant, you're in awe that anyone of us was born at all.

A possible pregnancy starts anew every month when the pituitary gland in a woman's brain signals her ovaries to prepare an egg for ovulation. This releases the follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Once the pituitary gland secretes these, thus stimulating the ovaries, a woman is fertile.

Generally speaking, this occurs about midway through a woman's menstrual cycle. If you have a 28-day cycle, this event happens at approximately day 14.

Once the hormones have prepared the ovaries, the woman's egg travels through her fallopian tube in anticipation of being fertilized. The window of opportunity here is usually 24 hours. The odds of conceiving are higher when intercourse takes place one, even two days, before the actual ovulation occurs.

While the female is fertile, it's necessary for the sperm to unite with the egg in the fallopian tube. The sperm, by the way, is capable of fertilization for up to 72 hours following its release. Obviously, the sperm need to be in the tube at the same time the egg is there.

But that's not all (and here's where Mother Nature gets real particular!), not only does there need to be a significant amount of sperm present to ensure conception, but the sperm needs to be just the right shape . . . and it needs to move in the proper way. Those are the requirements on the man's part.

For the woman, she needs to have a healthy vagina and uterus in order for the sperm to travel to the egg!

It's only when all these criteria are met that the egg is fertilized. .You would think that's the end of the story, but no, the process isn't quite complete, yet. This fertilized egg now must move into the uterus. Here it attaches itself to the uterine lining. And that's when the nine months of growth begin.

Finally!
Whew! As you can see, both the sperm and the egg are working on rather a tight schedule here -- a matter of hours really. The miracle of birth is a rather appropriate description of the entire process. Seen in this light, you have the inclination to look around you, thinking that any of us was able to show up in this world is pretty amazing!
