Male infertility is the inability of a man to impregnate a fertile woman after a year of unprotected sexual intercourse. Around 80 – 85 percent of couples will conceive naturally within 12 months of trying. After this time both partners should see their health care provider for fertility evaluation.
Male infertility is responsible for between 30 and 40 percent couples who are unable to conceive. Causes of male infertility are many and varied, but exciting advances in male infertility means there are a range of innovative therapeutic options available.
For sperm to be able to penetrate the egg it needs to be motile – meaning it should move actively rather than aimlessly. There needs to be sufficient numbers for a pregnancy to take place, and low sperm count is a very common fertility issue among men. On average about 100-750 million sperm are ejaculated during orgasm, but only a few make it to the fallopian tube and reach the egg for fertilisation. The shape of the sperm also influences its quality. Malformed or unusual shaped sperm often are unable to penetrate the egg.
Other problems can be caused by sperm trapped inside the testicles, inflammation of the testicles, sexually transmitted infections, testicles that don’t descend into the scrotum at birth and are damaged by staying in the body, genetic causes (such as Kilinefelter syndrome), cancer drugs, hormonal causes, varicocele (enlarged veins encircles the testicles) and poor quality of sperm after vasectomy reversal.
Other causes of male infertility includes cancer, trauma, hydrocele, malaria, testicular dysgenesis syndrome, idiopathic oligospermia (unexplained sperm deficiencies account for 30 percent of infertility problems in males), tobacco smoking, excessive alcohol consumption, abuse of drugs (both prescription and recreational), emotional stress, obesity and age.
It is important to detect and treat any correctible problems. In some men, a doctor’s exam may find an underlying medical problem that is causing the infertility.
Diagnostic exams may include:
It is essential that all necessary testing be done before going down the path of assisted reproduction. Your doctor will analyse the results of any fertility tests and provide an informed opinion and direction on the next steps.
Less than a decade ago, treatment for male infertility was limited to assisted insemination or IVF using donor sperm. Today, exciting advances in male infertility have introduced innovative therapeutic options and are offered to couples, to greatly improve their chances of conception.
Some of these options include:
Prognosis Of Male Infertility
More than half the cases of male infertility can be treated. In some cases treatment may help couples to get pregnant through normal intercourse; however, each case is different and it is important to take a doctor’s advice on next steps.
