A semen analysis is a very good starting point for finding out how fertile a man may be. A poor result may require referral for a DNA fragmentation test or to an urologist, and perhaps blood tests and ultrasound scanning will be advised. However a good result does not rule out other factors that may play an equally important role in infertility:
1. Infections - infection is a major cause of infertility that may not always produce any symptoms, but may result in so-called 'unexplained infertility' or miscarriages in the woman, if not treated in the man. Checking for, and treating any infection, is done for both partners if necessary.
2. Sperm Genetic Quality - for decades, semen analysis has been considered the definitive test to give a clear answer about male fertility. Current research, however, now shows that the genetic quality of the sperm is of primary importance, and that this is independent of the sperm count, motility and shape. A new test is now available which looks directly at the DNA (genetic) fragmentation in the sperm. Studies have shown that if there is a very high level of DNA fragmentation, the chances of a successful pregnancy are significantly reduced.
3. Age - is a major cause of DNA fragmentation as well as poor sperm quality. Plus, in later life men can suffer from hormone changes which can result in impotence or a decrease in libido.
4. Environmental pollutants - there are many studies in scientific literature that point to the effects of exposure to occupational hazards and pollutants in our environment, which appear to have a significant impact on sperm quantity and quality, and subsequently on a couple’s fertility.
5. Stress – The Clinic can provide a
counselling service for couples, or for just the male partner, if this is appropriate. Coping with fertility problems can be hugely stressful and can place substantial pressures on a relationship. Our resident psychotherapist or our counsellor is always available to help clients through what can be a particularly taxing period.
