Reproduction or giving birth to a child is a natural process. Some consider it as a blessing from the God. Because, some experience difficulty in conceiving. This disability of giving birth to a child is called infertility. Both the couples can be the cause for it. Which means that, either the husband or the wife can be infertile. Most people consider infertility as a very common condition among women and uncommon among men. This concept proved wrong with the studies and finding by researchers.
What is male infertility?
The inability of a man to cause pregnancy in a fertile female partner is called male infertility. It is found that in one man in five infertile couples ,the problem lies with the male partner. There are various factors which cause infertility in men. as well as in women.
Infertility may not show any signs or symptoms. The process of ejaculation, intercourse and erection will happen as usual. Sperm abnormalities are said to be the main cause of male infertility. Studies state that more than 90% male infertility cases are caused due to sperm abnormalities. Other main causes of male infertility are:
Causes In Detail
A wide range of factors is said to cause sperm abnormalities. Factors include certain diseases, chemical exposure, lifestyle habits, congenital birth defects etc. are said to affect the sperm count. Sperm abnormalities are categorized into three according to their effect on the sperm movement, sperm count, and sperm shape. They are called Low Sperm Count (Oligospermia), Poor Sperm Motility (Asthenospermia), and Abnormal Sperm Morphology (Teratospermia).
Low Sperm Count (Oligospermia): If one has a fewer sperm count that is less than 20million/mL is called Oligospermia or Low Sperm Count. Some may experience a complete absence of sperm cells in the ejaculate, which is known as Azoospermia. The sperm count can also be reduced due to a partial obstruction which may occur anywhere in the long passages. The sperm count may also vary according to the time. There can be temporary low sperm counts which is a common issue among most of the people. A single test may not be able to represent the entire result.
Poor Sperm Motility (Asthenospermia): The ability of sperm to move is called sperm motility. The sperm may face difficulty in invading the cervical mucus or penetrating the hard outer shell of the egg due to the slow movement or not being in the straight line. It is considered abnormal when 60% of the sperm have normal mobility and the rest 40% are not able to move in a straight line. Sluggishly moving sperm may have certain defects which will make the sperm to be inefficient to fertilize the egg. The condition of Asthenospermia may be associated with the DNA fragmentation. This will increase the risk of disseminating genetic disorders.
Abnormal Sperm Morphology (Teratospermia): Morphology is a term which indicates to the shape and structure. Sperms that are abnormally shaped will not be able to fertilize and egg. If 60% of the sperm are in normal size, fertility can be possible. A perfect sperm will be having an oval head with long tail.
Retrograde Ejaculation :
Instead of emerging through the penis during orgasm, sometimes the semen enters the bladderfrom the posterior urethra. This condition is known as retrograde ejaculation. In such condition, sperm quality will be damaged. This condition may be induced due to various reasons, such as:
Structural Abnormalities :
Fertility can also be affected by any structural abnormalities which may damage or block the tubes, testes or other reproductive structures. It may include:
Hormonal Deficiencies :
Genetic disorders are those conditions which are inherited in an individual from the birth itself. Some of them may impair the fertility of the individual. It may include:
I don’t know actually how to begin to thank you, as you have being the main and only source for bringing in and giving me the feeling of motherhood, which I once upon thought will never be possible.
You not only advised me in every step of my pregnancy but also guided me as to how I should go about everything, as most people say that a doctors comforting words are sometimes more powerful than
Nine months of my pregnancy could have been a nightmare without your medical supervision. Thanks for making my journey to become a mommy nothing less than a dream come true.
