The most common cause of female fertility problems is ovarian disorders; these are disorders which affect the ovary's ability to produce eggs. Women with ovarian disorders, such as PCOS (polycystic ovarian disorder), premature ovarian failure may produce very few eggs or no eggs at all, which makes it very difficult to conceive. Thyroid problems and long term health conditions, including cancer, can also affect ovulation. Click here to learn about infertility cure!!

Damage to the structures of the reproductive system, including the womb and the fallopian tubes may also cause problems with conception. This may also be the case if there is blockage in the tubes. Damage may be the result of surgery, infections and health conditions (including pelvic inflammatory disease) or trauma. Health conditions, such as endometriosis and submucosal fibroids can also affect fertility. Endometriosis is a condition which occurs when tiny pieces of the womb lining start to grow in other places, such as the ovaries and fallopian tubes.

Age is also a key factor when it comes to female fertility. Women's fertility lowers as they age and after the age of 35 the chances of conception decrease steadily. 95 percent of women aged 35 will get pregnant after 3 years of trying, while only 75 percent of women aged 38 will get pregnant after the same period of time.

Male fertility problems are usually associated with abnormal semen; common causes of male problems include a low sperm count, irregular-shaped sperm and poor sperm mobility. Infertility problems may also be caused by damage to the testicles (as a result of infection, trauma or testicular cancer), ejaculation disorders or a very low level of testosterone (known as hypogonadism).

Lifestyle factors can play a part in both female and male fertility; smoking and drinking affect both men and women and being overweight can reduce the chance of conceiving. Fertility experts advise couples who are trying to conceive to adopt a healthy lifestyle, which includes eating well, exercising, losing weight (if you need to), cutting down on drinking and giving up smoking.

Taking certain types of medication can also affect fertility. Drugs including neuroleptic medications (taken to treat psychosis), anabolic steroids, sulfasalazine (taken to treat rheumatoid arthritis and Crohn's disease) and illegal drugs can all affect fertility and long-term therapies, such as chemotherapy may also have an adverse affect on fertility.
