Sperm abnormalities contribute to the problem in half of all cases of infertility. So the first step is a semen analysis.
Sperm quality does vary considerably and often repeated testing is necessary. There are also more advanced tests such as sperm DNA fragmentation.
Men can also be tested for their karyotype (chromosomes) and hormone levels, especially if their sperm count is very low.
Treatments range from lifestyle changes and supplements to IVF/ICSI and testicular bioposy.
In all cases of male infertility, the female partner also needs a thorough assessment.
