Infertility is defined as not being able to become pregnant after having regular intercourse without birth control after one year (or after six months if a woman is 35 years or older). Out of 100 couples in the United States, about 12 to 13 of them have trouble becoming pregnant.
The main causes of infertility are due to ovulation problems or blocked fallopian tubes. There are also chances of decreasing fertility in cases of endometriosis, radiation therapy, or thyroid problems. Female infertility is treated in various ways, often including medication or surgery, however treatment is not always successful.
