Causes On The Female Side

If the uterus is abnormal, the fertilized egg can no longer be implanted or may cause miscarriage. Some women have uterine abnormalities when they were born and others are caused by uterine fibroids or endometriosis. If you have abnormal bleeding, have menstruation for a long time, or have bad menstrual pain, you should get a test as soon as possible.

Main Causes:

Uterine factor

Uterine fibroids are benign tumors that form in the muscle layers of the uterus. There are three types: submucosal fibroids that protrude inward, intramuscular myomas that form in the myometrium, and subserosal fibroids that form on the outside of the uterus. The closer the tumor is to the uterine lumen, the more likely it is to affect pregnancy.


It is a disease in which the tissues that can be formed inside the uterus grow into the myometrium, ovaries, fallopian tubes, and abdominal cavity. A study says that 1 out of 10 young women get endometriosis, and 1 out of 3 during infertility treatments has one.

These days, this is kind of getting common disease among women who are on treatment for infertility.

Uterine malformation

There are two uteri when you are pregnant as you have two kidneys and lungs. Then eventually they will merge into one. However, some babies are born with poor fusion and become uterine malformations. If you have a uterine malformation, the implantation rate tends to decrease slightly, or the miscarriage rate increases.

Endometrial polyps

It is a mushroom-shaped intima that is frequently seen in those who start infertility treatment. Polyps may get in the way and fertilized eggs may not be able to be implanted.

Other Causes:

Luteal dysfunction

After ovulation, progesterone is secreted from the ovaries to promote the implantation and development of the fertilized egg. When the high-temperature phase of basal body temperature does not last for more than 10 days and progesterone level in the blood during the mid-high-temperature phase is 10 ng / ml or less, luteal dysfunction is diagnosed.

Anti-sperm antibody

A miscarriage due to a chromosomal abnormality is accidental, but repeating a miscarriage twice is called a repeated miscarriage, and repeating a miscarriage more than three times is called a habitual miscarriage.

Unexplained infertility

Even if you take some tests, the cause of infertility is not found sometimes. And It’s called functional infertility. In this case, you will take step-up treatment such as…the timing method → ​​artificial insemination → in vitro fertilization

Causes on Male Side

It is known that the cause of infertility is not only on the female side but about half is also on the male side. There are three main causes of male infertility.

Impaired spermatogenic function

Non-obstructive azoospermia in which sperm is not made in the testes, oligospermia with a small number of sperm, asthenozoospermia with low motility. The varicocele of the spermatic cord is a symptom in which the vascular valve in the testis malfunctions and blood circulation worsens, varicose veins form near the testicle, the testicle temperature rises, and the sperm dies.

Spermatic disorders

The epididymis or vas deferens is obstructive azoospermia where sperm is not mixed with semen and retrograde ejaculation disorders where semen flows back into the bladder.

Ejaculation disorder
