Although male infertility may be attributed to a number of conditions, we can still find that some issues are more prevalent than others. Here are some of them, in no particular order:
Blockage of Sperm – the possibility that the passages carrying the sperms towards their destination is high.
This may be due to vasectomy, physical anomaly, infection, or injury. For a male to be infertile, he must be capable of successfully delivering sperms cells towards the female by means of these passages (e.g. vas deferens). Natural fertilization occurs when nothing impedes the sperm cells from flowing to their proper points.
Erectile Dysfunction (ED) – the problem comes when a man is incapacitated for erection. Without this, it would be almost impossible to deliver sperm cells out from the male’s body.
This condition may be attributed to a number of chronic diseases which include heart problems and hypertension. Too much alcohol in the body may also lead to erectile dysfunction. And to say the obvious, paralysis may largely contribute to ED.
Infections – these may arise from conditions that were recently incurred or those that may have manifested during childhood.
Infections may cause low sperm count and sterility.
Failure to Produce Sperm – a condition is also known as azoospermia. Temperature is the leading cause why this condition appears.
Since sperm cells are by nature extra sensitive, the slightest heat may cause them to die and eventual cessation of the production of cells may result.
However, other conditions may pop-up such as abnormal cells or lessened sperm movements. Any phenomenon that may raise the normal body heat during a long period of time may affect the condition of the sperm cells. This can be anything from prolonged fever, exposure to too much heat due to chemotherapy, varicocele or the presence of varicose veins in the testes and undescended testes.
Nonetheless, genetic disorders and certain hormonal abnormalities may intrude on the normal and healthy production of sperm cells.
Such may include hypothyroidism, hyperprolactinemia, hypogonadism, adrenal gland disorders (the organ responsible for the secretion of testosterone a number of other hormones), an abnormality of the pituitary gland (which controls the release of the testosterone).
While we have discussed the biological reasons for the decrease in the production of sperm cells (and the lack thereof), we must still take into account other conditions that can cause abnormalities in the testes.
These may include previous diseases and ailments, excessive use of drugs, and exposure to environmental toxins.
More serious cases may be attributed to lack of seminal vesicles, missing or blocked vas deferens, and obstruction in the ejaculatory ducts and serious injuries of the testes.
