Infertility is the inability or failure to conceive after one year of regular sexual intercourse without contraception. There are two categories to classify infertility, primary and secondary. Primary infertility occurs in women who have never conceived while secondary infertility occurs in women who have had a previous conception. There are many causes of infertility which affect approximately one in six couples. Just over half of infertility cases are attributed to female conditions. Female conditions include ovulatory dysfunction, tubal or pelvic factors, cervical problems, and uterine factors. However, this does not exclude other conditions as well. These include male factors and unexplained infertility. Male factors are pretesticular causes, testicular factors, and posttesticular causes. Recent research has shown that the increase in infertility from one in ten couples to one in six couples is due to lifestyle factors. Delay in pregnancy, habits such as cigarette smoking and alcohol, changes in sexual behavior and the elimination of most taboos contribute to the increase in infertility in many couples. Cigarette smoke and the substances it contains such as nicotine have negative effects on reproduction. It also causes lower circulating levels of estrogen and earlier menopause. For men, smoking decreases sperm quality. Alcohol has been found to increase the risk of tubal and cervical factor infertility and ovulatory dysfunction. In males, alcohol has been found to increase abnormal sperm formation, can lead to impotence, and negatively affect male hormone levels. These lifestyle factors have negative effects on reproduction as they are believed to change the regulation of hormones in both males and females, causing infertility. One of the most common female infertility factors is ovulatory dysfunction also known as anovulation, as mentioned above. It is a disorder in which ovulation does not occur regularly. The causes of ovulatory dysfunction range from disruption of hormonal regulation of the female cycle to underdevelopment of the reproductive organs in a woman, they are mostly related to the imbalance of hormones. It can occur in any woman who has gone through puberty and is common in women approaching menopause, when women stop ovulating.

Technology gives humans more control over procreation. It has the potential to cause a revolutionary change in how we perceive reproduction. The moral behind this technology requires consideration and attention since the embryonic cells that are destroyed are still life destroyed. Therefore, researchers must take into account the principles of what they are doing and make decisions that will weigh heavily on morality. Although somatic cell nuclear transfer is a good option for conceiving children for infertile couples, they must carefully consider whether they want it. address the associated risks. Furthermore, they must think for the child that might be conceived. As revolutionary as it may seem, this infertility treatment option is still being developed and evaluated. Therefore, they must think wisely about their decisions. Ultimately, it's their decision, but their decision would affect their life. If this new life science technology was given more time to be developed and studied, perhaps it could be made available in a decade or so and..
