More than 90% of male infertility causes are low sperm counts, poor sperm quality or both. The remaining causes are due to genetic defects, anotomical problems (e.g. blockages) or hormonal imbalance. Luckily, for most men, if the cause can be identified it is usually reversible. In many cases, fertility levels can be significantly improved through diet and lifestyle changes. Sperm are continuously produced throughout a mans lifetime in a cycle which takes approximately 3 months to complete.
In order for pregnancy to occur, a man must produce sperm that are strong and healthy enough to reach the egg and fertilise it.
Problems with male fertility are usually associated with factors that either affect sperm production or sperm transport.
There are usually no obvious signs or symptoms to determine whether a man has a reduced fertility level. The only conclusive test is to have Semen Analysis carried out. This test will give information on Sperm Count, Sperm Motility (swimming ability) and Sperm Morphology (shapes).
Since sperm are constantly being produced in the testicles it is possible to improve a poor sperm count or increase the motility level of sperm through diet and lifestyle changes.
