Abstract
In general, infertility is defined as not being able to get pregnant (conceive) after one year (or longer) of unprotected sex. Worldwide 8 to 12 percent of couples experience fertility problems. Infertility is a big health problem worldwide as it has been estimated that in 2010 there were 48.5 million (45.0 million, 52.6 million) infertile couples worldwide. Due to population growth, however, the absolute number of couples affected by infertility increased from 42.0 million (39.6 million, 44.8 million) in 1990 to 48.5 million (45.0 million, 52.6 million) in 2010. Among the various regions in the world, South East Asia and Sub-Saharan Africa countries have the highest prevalence of infertility. The inability to have children affects couples worldwide and causes emotional and psychological distress in both men and women. Many factors including physiological, genetic, environmental, and social contribute to infertility. If you have fertility problems, the treatment you’re offered will depend on what’s causing the problem. There are 3 main types of fertility treatment: medicines (If you have ovulation problems), surgical procedures (If you’ve been diagnosed with tubal or pelvic disease) and Assisted Reproductive Technology (ART) (including intrauterine insemination (IUI), Intracytoplasmic sperm injection (ICSI) and in vitro fertilisation (IVF). ART works by removing eggs from a woman’s body. The eggs are then mixed with sperm to make embryos. The embryos are then put back in the woman’s body. In 2010, Robert Edwards received the 2010 Nobel.
