Understanding Fertility in Men
Conceiving a baby is influenced by a number of factors, including healthy sperm. After a woman’s age, male infertility is the second biggest cause of pregnancy delay and affects almost half of all couples having trouble conceiving.
Problems with male fertility account for about 40% of all cases of infertility. Find out how the male reproductive system works, and the impact of low sperm motility.
The good news is that the most common causes of male infertility are easily diagnosed and successfully bypassed with effective fertility treatments including IVF with Intracytoplasmic sperm injection (ICSI).
Most causes of male fertility problems are related to defects in the quality or quantity of sperm produced or disruption to the sperm emission. Find out more about sperm production on this link.

The entire process of sperm production and maturation takes just under three months. Any serious illness may affect sperm production for up to three months.
To successfully fertilise an egg, the sperm will need to have good motility (be able to move its tail) to propel itself through cervical mucus to then travel through the uterus and fallopian tube to reach the egg. It will also need to be normally shaped in order to penetrate the outer shell of the egg to deliver the genetic package contained in its head.
Female age is the most significant factor affecting a couple’s chance of conceiving. In 40% of infertile couples, the cause of infertility is attributed to a sperm factor. In another 40% of infertile couples, the cause of infertility is found within the female reproductive system, such as ovulation failure, tubal disease or endometriosis. One third of all infertile couples will have a combination of female and male factor infertility.
