Factors of Miscarriage:


90 percents of miscarriages occur due to genetic issues. A baby inherits 23 chromosomes from each parent. If either of the chromosomes is defective or missing, it may lead to complications that may result in a miscarriage.


Sometimes a woman may suffer from infections of cervix or uterus such as mycoplasma, Chlamydia, ureaplasma or gonorrhea. All such kinds of infections may prove to be fatal for the growth and development of the growing baby and may lead to a miscarriage.

Progesterone Deficiency

Progesterone is a very important hormone during pregnancy. Sometimes when the body is unable to produce ample amounts of this hormone in the body, a miscarriage may take place.
