What is Male Infertility Problems?
Male infertility is diagnosed when, after testing of both partners, reproductive problems have been found in the male partner,
Infertility is a widespread problem. For about one in five infertile couples the problem lies solely in the male partner (male
Male infertility can be caused by problems that affect sperm production or the sperm transport process. With the results of medical tests, the doctor may be able to find a cause of the problem.
Known causes of male infertility can be:
Sperm production problems: The most common cause of male infertility is due to a problem in the sperm production process in the testes.
Low numbers of sperm are made and/or the sperm that are made do not work properly. About two thirds of infertile men have sperm
Blockage of sperm transport: Blockages (often referred to as obstructions) in the tubes leading sperm away from the testes to the penis can cause a complete lack of sperm in the ejaculated semen.
This is the second most common cause of male infertility and affects about one in every five infertile men, including men who have had a vasectomy but now wish to have more children.
Sperm antibodies: In some men, substances in the semen and/or blood called sperm antibodies can develop which can reduce sperm movement and block egg binding (where the sperm attaches to the egg) as is needed for fertilization. About one in every 16 infertile men has sperm antibodies.
Sexual problems: Difficulties with sexual intercourse, such as erection or ejaculation problems, can also stop couples from becoming pregnant. Sexual problems are not a common cause of infertility.
Hormonal problems: Sometimes the pituitary gland does not send the right hormonal messages to the testes. This can cause both low testosterone levels and a failure of the testes to produce sperm.
