Cancer treatment can interfere with ejaculation by damaging the nerves that control the prostate, seminal vesicles, and the opening to the bladder. It can also stop semen from being made in the prostate and seminal vesicles, or it can cut off the path that semen normally takes out of the body. Despite this, a man can still feel the sensation of pleasure that makes an orgasm.
Having a baby is generally a simple and natural experience. However, for some couples it can be difficult to conceive a child. As a male, your fertility generally depends on the quantity and quality of your sperm.
If you and your partner are struggling to have a baby, you're not alone. Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most couples. Infertility may result from an issue with either you or your partner, or a combination of factors that prevent pregnancy. Fortunately, there are many safe and effective therapies that significantly improve your chances of getting pregnant.
Sperm gets ejected from the penis, enters the vagina, and swims up the reproductive tract until they reach the egg to fertilize it. Barely years ago, it was considered a major scientific breakthrough when scientists came up with the idea that a fully formed, tiny human inhabited the head of each sperm — totally debunked and untrue. Fortunately, as the human body has evolved over thousands of years to maximize fertility potential, so has our scientific understanding about sperm.
Five percent of infertile men have azoospermia, or an absence of sperm in the ejaculate. But thanks to advanced medical treatments, men with azoospermia do not have to give up their hopes of conceiving a child. Depending on the type of azoospermia, it may be surgically treatable with a return of ejaculated sperm or it may require sperm retrieval and assisted reproduction to achieve pregnancy.
Infertility is the inability of a sexually active couple, not using any birth control, to get pregnant after one year of trying. Problems in the male partner affect about 40 percent of infertile couples. In about 30 to 40 percent of cases, the problem is in the testes, the glands that produce sperm and testosterone the main male sex hormone.
Back to Health A to Z. A low sperm count, also called oligozoospermia, is where a man has fewer than 15 million sperm per millilitre of semen. Having a low sperm count can make it more difficult to conceive naturally, although successful pregnancies can still occur. Problems with sperm, including a low sperm count and problems with sperm quality, are quite common.
If a man cannot release or make healthy sperm naturally, this medical procedure may be recommended for fertility reasons to enable the man to father a child. The testicular tissue is found in the two testes, where the sperm is made. The testes are found inside the scrotum, the small sac behind and under the penis.
Men who are diagnosed as azoospermic -- infertile because of an absence of sperm in their ejaculate -- are more prone to developing cancer than the general population, a study led by a Stanford University School of Medicine urologist has found. And a diagnosis of azoospermia before age 30 carries an eight-fold cancer risk, the study says. Eisenberg is lead author of the study, published online June 20 in Fertility and Sterility. Diagnoses of male infertility and azoospermia are surprisingly common in the United States.
