A miscarriage is never forgotten. It doesn’t matter if it was one week ago or several years, because it’s not just a "miscarriage", but the BABY that has been lost and could be next to you right now.

So if you endured this kind of loss and you’re fearful it may arise again, learning about the causes of miscarriages will help you prevent them and have an accomplished pregnancy that will bring to you a marvelous and healthy child.

These are the 3 Most Common Causes of Miscarriages:

Genetic Causes

Genetic causes of miscarriages usually happen because of an advanced maternal age. The reason of this is that, as you age, your body starts to deteriorate; and after 35, your eggs start to "loose their freshness" and develop genetic issues, so try to keep in mind the relashionship between age and fertility when evaluating your conception plan.

If the miscarriage happens before the 12th week of pregnancy, probabilities are there is a genetic cause that provoked it. Another characteristic of genetic causes of miscarriages is that it is usually a single event. This indicate that if you had a second or a third miscarriage, chances are it’s NOT because of a genetic problem.

Nonetheless, if you are trying to conceive and you are over 40, it is highly recommended that you consider the possibility of looking for a donor of eggs.

The child will still be developed in your womb, but you will be using "fresher" eggs that have less chances of having a genetic anomaly.

Physical Causes

The physical causes of miscarriages are mainly related to 2 parts of your body involved with reproduction. Your cervix and uterus.

The uterus is commonly known as the womb, and its function is to nurture and hold the baby while it develops inside of you. The cervix is a muscle in the lower part of the uterus that mantains the baby in its place until the moment of birth comes.

The causes of miscarriages related to the uterus are:

- Malformations in the uterus:

Most common are "Septate uterus" or "Two horn uterus".

What they cause is that the space inside your womb gets divided or reduced by strings of tissue, affecting the full development of the embryo because it doesn’t have enough space to grow the way it’s supposed to.

- Malformations in the cervix:

Incomplete cervix

Think of the cervix as the door to the uterus. If you happen to have an undeveloped cervix, when the embryo has reached certain size, it will start putting pressure against it, and if the cervix doesn’t have the strenght to hold him, this could very easily lead to a miscarriage.

Malformations are causes of miscarriages that are intricate to deal with. Nonetheles, they can be fixed using surgical procedures.

To know if you may have any of these internal issues, make an appointment to your gynecologist or fertility endocrinologist to practice yourself an ultrasound. This is usually enough to find out, however, if the ultrasound results are not very clear, the next process would be to do a Laparoscopy, which is a minor surgery that allows the doctor to look inside your uterus.

Hormonal Causes

Hormones are the chemicals produced by your brain to give signals to all the organs of your body. Progesterone is the most important hormone that controls of all your reproductive functions.

Hormonal causes of miscarriages happen when the creation of Progesterone falls out of balance and starts altering the way your body controls pregnancy, including your menstrual cycle and the inner lining of your uterus.

The most common cause of hormonal miscarriages is a condition called Polycistic Ovaries Syndrom (PCOS), which starts producing a great number of masculine hormones (testosterone) and less quantity of feminine hormones (progesterone).

Some of the symptoms of PCOS are

-High blood pressure

-Growth of unwanted body hair

-Oily skin


-The absence of your period or too much irregularity on it

To reduce your chances of miscarriages when conceiving with Polycystic Ovaries, you should follow a treatment with a fertility specialist or a qualified gynecologist.

These treatments usually consist on the prescription of substances to regulate your hormonal production; such as a very popular fertility drug called Clomid, exercise and a healthy diet.

These are the main causes of miscarriages you should know to improve your chances of having a secure pregnancy and giving birth to a healthy child.

However, there is ONE MISTAKE many women with recurring miscarriages issues make that could put in danger your health, your pregnancy and the health of your baby.
