Like a woman, a man has several important organs needed to create a new life – your baby. Without healthy male reproductive organs even a woman who can easily conceive will not. Now, let’s look at some of the things that can affect a man’s ability to impregnate his wife:

The Penis
Does size really matter when it comes to getting your gal pregnant? No, not really, as long as the penis is big enough to get the sperm into the vagina and up toward the cervix. However, function is very important in regards to a male’s fertility. Impotence or an inability to either have or sustain an erection can make it difficult to create a pregnancy.
Other problems can occur when the penis is not formed correctly. It is important that the opening that lets the sperm out of the penis be at the center of the penis’ tip. There are two main variations that can cause problems getting pregnant: Hypospadias – affects about one in 300 men. It is caused when the opening is on the underside of the penis.Epispadias is caused by the opening at the top of the penis, and is much rarer (only affecting one in 100,000 men).
Both of these conditions are associated with an unusual curvature of the erect penis -- it curves up in epispadias and down in hypospadias – and can prevent the sperm from getting where it’s needed in order to fertilize the woman’s egg.

The Testicles
A man’s testicles both produce and store sperm. It is vitally important for the testicles to be kept a few degrees cooler than 98 degrees for sperm to develop properly. That’s why it is so important for men with one testicle larger than the other to be checked for both hydrocele, a collection of fluid inside the scrotum; and varicose, varicose veins in the testicle, which can both raise testicle temperature and cause infertility.Unlike a woman’s eggs, which are present at birth, a man continues to produce sperm throughout adulthood.Although produced every day, it does take about two months for a man’s sperm to fully mature. The process begins in the testes, where FSH and LH hormones
begin making sperm and testosterone. Once the sperm mature in the epididymis, they travel through the vas deferens up to the seminal vesicle and the prostate, where they are submerged in semen and finally ejaculated through the urethra and into the woman’s vagina during intercourse.

The Sperm
Without sperm there would be no babies. Without enough of them your chances of becoming pregnant lessen. Every time a man ejaculates, about - 200 million sperm are released. That should certainly be enough to fertilize one little egg now shouldn’t it? Maybe not! Within a few hours that 200 million has dwindled to a paltry 100 million. Their job has just gotten harder. The journey to the egg is long and difficult. First, the sperm needs to know in which direction to swim (statistics show that almost half go in the wrong direction – maybe they should stop and ask for directions!).Next, they actually have to get moving. Many lag behind. Meanwhile, the woman’s body isn’t necessarily friendly, killing off thousands of others along the way. For the lucky few, success can be found, but only if they are strong enough and persistent enough to make it through the long arduous journey.
