Though the help of our modern medical science or experts we are able to find out lots of causes of female infertility such as,

Ovulatory disorders: Ovulatory issues are one of the main causes of infertility. It is a disorder, in which woman’s eggs don't grow appropriately / the women's egg quality is not appropriated to become an embryo / the egg is not discharged from the follicles of the ovaries. Females with ovulatory disorders may or may not have regular menses.

Endometriosis: Endometriosis is an agonizing, endless illness that influences millions around the world. It happens when the lining of the uterus (tissue called the endometrium) is found outside the uterus - as a rule in the midriff on the ovaries, fallopian tubes and ligaments behind the uterus; the part between the vagina and rectum; the external surface of the uterus; and the coating of the pelvic depression.

This misplaced tissue forms into developments or sores which react to the menstrual cycle in the same way that the tissue of the uterine covering does: every month the tissue develops, separates and shed cause of that people faces lots of complication such as,

• Pain during Sexual intercourse.
• Infertility.
• Pain before and during menstrual cycle.
• Painful bowel movements during period.

Age: A lady's best reproductive years are in her 20s. Fertility step by step decreases in the 30s, especially after age 35. Every month that she tries, a sound, young fruitful 25-year-old lady has a 20% shot of getting pregnant.

Pelvic Adhesions: Adhesions are scar tissue that can be formed inside the pelvis and causes organs to be stuck together when they shouldn't be. Frequently, Adhesions are the after effect of past surgery, infections. however some can happen taking after pelvic contamination and ordinarily they go with more serious phases of endometriosis. Some of the symptoms are like,

• Pelvic Pain
• Abdominal Pain
• Cramping
• Nausea
• Pressure
• Blockages

Uterine Fibroids: Uterine fibroids are exceptionally normal non-dangerous (benevolent) developments that grow in the body of the uterus. They can go vary in size from exceptionally little (a quarter of an inch) to bigger than a melon. Very often, the uterus develops to the extent of a five-month pregnancy.

Much of the time, there is more than one fibroid in the uterus. While fibroids don't generally cause manifestations, their size and area can prompt issues for a few ladies, including infertility, excessive bleeding during periods, agony. Fibroids can drastically increase in size during pregnancy.

Polycystic Ovarian Disease:Polycystic ovary disorder is an issue in which a lady's hormones are imbalanced. It can bring about issues with your periods and make it hard to get pregnant. PCOS likewise may bring about undesirable changes in the way you look. Over years it can even lead to other problems like, diabetes and coronary illness.

Some other factors that may play a part of female infertility such as :

• When no reason is identified. (unknown infertility)
• Genital tuberculosis
• Medical conditions such as diabetes, epilepsy and thyroid and bowel diseases.
• Having previous ectopic pregnancy with more than one miscarriage.

Ejaculatory Dysfunction: With most of the cases Ejaculate Disorder is characterized either when a male fails to deliver the sperms into the vagina or he ejaculates prematurely (too quickly) during sexual intercourse.

Impotence or the inability to maintain an erection for intercourse, can be caused by a high blood sugar level (diabetes) which causes nerve damage, smoking, excessive alcohol intake, fat diet (fatty deposits clog the arteries in the penis), by high blood pressure and the drugs used to treat high blood pressure.

Deficient Sperm Production:About 90%of couples with male infertility have the problem of poor sperm production (they are incapable to produce motile, healthy sperms to conceive a child). However people believe that 5 million/ml or above sperm count is necessary to fertilize an egg but the reality is that also with less than 5 million sperm count, a lady can conceive if the male is producing healthy, sufficient and motile sperms.

Damage related to Cancer:Treatment for cancer, radiation therapy or chemotherapy can also impair sperm production sometimes. Removal of one of the testicles due to any disease like cancer also may affect Male fertility.

Infection: Around 30% to 75% of infertility in men, is due to some infection of the reproductive organs. The presence of anti-sperm antibodies, which assault and obliterate the sperm are normally a decent marker that an infection is present. Such diseases are typically treated with antibodies or anti-toxins.

Ductal Obstruction:Ejaculatory Duct Obstruction presents with a low discharge volume on semen along with no sperm number or low sperm motility. Ejaculatory conduit impediment is the reason for fruitlessness in 1-5% of infertile men. Albeit abnormal, ejaculatory conduit block is determined and treated to have negligibly intrusive procedures.

Some other factors that may play a part of male infertility such as :

• Genetic problems.
• Inflamed testes (Orchids) (due to infection like tuberculosis, mumps, sexually transmitted diseases etc).
• Diabetes.
• Having medical treatment such as drug treatment, radiotherapy or surgery– for example to correct a hernia, undescended testes or testicular torsion twisted testicles.
• Also affected by lifestyle factors such as being overweight or having a job that involves contact with chemicals or radiation.
