Causes of Male Infertility

Sperm production

What are sperm, how are they produced, how long does it take and what if there are no sperm produced…?

Low Sperm Count

Too few sperms in the ejaculate, read more

Poor Sperm Morphology

Most sperm are misshapen but that doesn’t matter

Poor Sperm Motility

Fertility cannot be achieved if the sperm cannot swim to the egg, sperm motility

Antisperm Antibodies

Low levels of these are nothing to worry about but

DNA Fragmentation

Unproven but suggested by recent research, high levels of DNA fragmentation may reduce sperm viability. Read about the test

Blocked Tubes and Vasectomies

Does this mean no more children? No it does not

Damaged Testes

Their effect on your fertility

Medical and Environmental fertility problems

The testes hang outside the body and are designed to be two degrees cooler than the rest of the body. The sperm is susceptible to damage from excess heat which could be caused by underwear holding the testes tight against the body or by excess saunas or hot baths. Some medical conditions or medication can reduce sperm count either temporarily or permanently. Abuse of anabolic steroids or recreational drugs can leave a lasting effect as can exposure to radiation or chemicals.

Sexual, Erectile or Ejaculatory dysfunction

All these can result in male infertility but there are a number of solutions available to, or recommended by, your doctor.

Genetic Infertility problems

Genetic problems can affect fertility or the health of future progeny. For example, certain problems, such as blocked vas deferens have been linked to the presence of cystic fibrosis genes. These kind of genetic problems are usually inherited rather than being first generation mutations and can often be identified through family histories. Testing can be of the parent to identify whether he is a carrier, or of the embryo through a process called pre-implantation genetic diagnosis, to see whether it has dominant copies of the mutated gene.
