Recent research has shown that the increase of infertility in one in ten couples to one in six couples is due to lifestyle factors. Delayed childbearing, habits such as cigarette smoking and alcohol, changes in sexual behaviour and eliminations of most taboos contribute to the increase in infertility in many couples. Cigarette smoke and substance in it such as nicotine has adverse effects on reproduction. It also causes lower circulating levels of estrogen and earlier menopause. For males, smoking decreases sperm quality. Alcohol has found to increase the risk of tubal factor and cervical factor infertility and ovulatory dysfunctions. On males, alcohol is found to increase abnormal shapes in sperm, can lead to impotence, and adversely affect male hormone levels. These lifestyle factors have adverse effects on reproduction as they are found to be able to change the regulation of hormones in both the male and the female, resulting in infertility.

Also, they must think for the child that might be conceived. Revoluntionary as it seems, this option to treat infertility is still in the process of being developed and assessed. Thus, they must think through their decisions wisely. Ultimately, it is their decision but their decision would affect their lifetime.

Unfortunately, some families are unable to have a child due to unforeseen problems, and they must pursue other means than natural pregnancy.
