6 Causes of Recurrent Miscarriage


Recurrent miscarriages can be due to genetic defects in either the egg or the sperm.

Men and women over 35 have a greater chance of this problem occurring as the eggs and sperm may not be as healthy as they were in their younger years.

Blood Clotting

Blood that is overly thick or has a tendency to clot can cause miscarriages.

Small blood clots can develop in the uterus cutting off the placenta and leaving the foetus void of the oxygen and nutrients it needs to survive.


The structure of the uterus can cause Reoccuring miscarriages.

This could be due to a misshapen uterus, incompetent cervix, large uterine fibroids, or severe Asherman’s syndrome.


Sometimes the body can attack the foetus or sperm; this can be caused by elevated natural killer cells or HLA incompatibility.

This is called an immunological disorder or immune system-based miscarriage.

High Homocysteine levels

High Homocysteine levels can cause a condition called hypercoagulability.

Blood clots much more easily and can put you at a higher risk for a heart attack and stroke. It can also put your baby in danger as well.

Hormone Imbalance

The hormonal system is an intricate orchestra of hormones that runs on a very specific schedule. If one of these hormones is out of balance, it can affect the rest of the cycle and impact early pregnancy.

Some of these imbalances may be:

Low Progesterone

High Oestrogen

Elevated Prolactin

Insuline Resistance

Thyroid Disorder

Luteal Phase Defect
