07 Apr Fertility and Life Style
Besides age, lifestyle can have an impact on fertility. Smoking, excessive drinking and drug addition can affect fertility and may cause higher risk of having a miscarriage and abnormal babies. Nicotine and other harmful chemicals in the cigarettes can cause menses to be irregular and menopause to set in earlier. Alcohol, cigarettes and marijuana can also affect the quality and quantity of the sperm. Environmental pollutants such as lead, mercury and DDT in pesticides are harmful to sperm.
Sexually transmitted diseases such as Chlamydia, gonorrhoea, herpes, and syphilis can damage the reproductive system and cause infertility. Obesity can also cause irregular menses in women and sperm abnormalities in menses.
Stress causes the menstruation to be irregular and gradually absent. In men, erectile dysfunction (impotence) and reduced sperm count and quality are becoming more common. Stress can also suppress the sexual desire thereby reducing the frequency of sexual intercourse. This is a common phenomenon in an affluent society like Singapore.
