Difficulties in becoming parents affect 15 percent of couples in developed countries, but in some countries like Spain, this figure rises to 18 percent, where 3 percent of babies are born with assisted reproductive techniques.

Infertility is a condition that affects both men and women. It is estimated that in 40 percent of the cases the origin is male, in another 40 percent the origin corresponds to the woman and in the remaining 20 percent it has a mixed cause. In this case, we explain what the main causes of female infertility are.

Infertility is diagnosed when a couple tries unsuccessfully to get pregnant within a year. But not only that, if the woman manages to become pregnant but suffers spontaneous abortions, we are also faced with a situation of female infertility.

Rates of female infertility are increasing, in part because the mean age at which a woman begins attempting pregnancy is falling behind (the highest peak of a woman's chance of pregnancy is generally between 22 and 26 years).

The truth is that, after 35 years, the reproductive potential of women decreases, after 40 years the probability of getting pregnant is less than 10 percent.

There are different factors that indirectly affect infertility, are what we call risk factors:

1. Age
As we have mentioned previously, it is one of these risk factors.

2. Tobacco
As in men, tobacco affects women very negatively, causing damage to the fallopian tubes and the cervix. And not only that, the probability of having a miscarriage in smokers is higher than in non-smokers.

3. Weight problems
Being overweight or underweight can affect ovulation. Being overweight causes hormonal imbalances that affect a woman's menstrual cycles and thus can interfere with ovulation and hinder the ability to conceive. On the other hand, a lack of weight can affect menstrual cycles, a BMI (Body Mass Index) less than 18.5 can cause ovulation to stop.

4. Alcohol
The moderate consumption of alcohol does not affect the fertility of the woman, but in the case of excessive consumption, things change. Alcohol can affect the production of ovules by altering the woman's body by releasing free radicals. This can transform into the absence of menstruation or ovulation disorders. In the case of achieving pregnancy, the woman with excessive alcohol consumption has a higher risk of suffering a spontaneous abortion than the one who does not consume alcohol or does so in a moderate way.

5. Sexual history
Sexually transmitted diseases like gonorrhea can damage the fallopian tubes.

As causes that act more directly on infertility we can mention:

1. Injury to the fallopian tubes (tubal factor)
The obstruction, or lack of patency, of the fallopian tubes is a serious inconvenience to allow pregnancy, since you are in charge of the displacement of the sperm until it meets the oocyte produced by the ovary.

If only one of the two tubes is obstructed, it is possible to achieve a natural pregnancy, but if both are obstructed, it is necessary to carry out an assisted reproduction procedure such as in vitro fertilization.

2. Endometriosis
The endometrium is the lining of the uterine cavity, and its function is to house the zygote after fertilization. When this lining is located outside the uterine cavity, we have a problem to have a successful pregnancy.

This is because in this situation, the quantity and quality of the ovules is affected and sometimes it also affects the fallopian tubes, decreasing their functionality.

When it prevents pregnancy, it is necessary to go to an assisted reproduction treatment.

3. Disorders in ovulation
One in four couples with fertility problems suffer from ovulation disorders, this can be due to failures in the regulation of reproductive hormones or problems in the ovaries.

4. Chronic diseases
Such as cancer, asthma, diabetes, depression, etc. or taking medicine to treat these disorders.
