2. What is the incidence of infertility worldwide?
The World Health Organization (WHO) estimates that approximately 8-10% of couples experience some form of infertility problems. On a worldwide scale, this means that 50-80 million people suffer from infertility. However, the incidence of infertility may vary from region to region.
3. Is infertility exclusively a female problem?
No. The incidence of infertility in men and women is almost identical. Infertility is exclusively a female problem in 30-40% of the cases and exclusively a male problem in 30-40% of the cases. Problems common to both partners are diagnosed in 10-15% of infertile couples. After thorough medical investigations, the causes of the fertility problem remain unexplained in only a minority of infertile couples (5-10%). This is called unexplained infertility.
4. What are the most common causes of infertility?
The most common causes of female infertility are ovulatory disorders and anatomical abnormalities such as damaged fallopian tubes. Less frequent causes include, for example, endometriosis and hyperprolactinemia, thyroid gland related problems. In developing countries like India, infections of the womb such as gonorrhoea, chlamydia and tuberculosis significantly, contribute to infertility.
