Inflammation and fertility: The factor that almost no one evaluates before trying to conceive

Inflammation and Fertility: The Factor That Almost No One Evaluates Before Trying to Conceive

Below we will discuss a topic that is uncommon and rarely mentioned, yet deeply studied within the stage of fertility.

It is a fact that fertility and the process of conception are influenced by multiple factors. Among the most well-known are daily habits, lifestyle, nutrition, physical activity, and the absence of harmful habits. Mental health also plays a fundamental role, as well as the proper management of stress and anxiety, and emotional balance.

In some cases, fertility can be affected by genetic factors or pathological conditions. In others, not only the reproductive health of the woman plays a role, but also that of the man. Conception is a shared, complex, and deeply multifactorial process.

Each of these factors has been widely explored and researched. However, there is one that is rarely discussed in everyday conversations, yet science has studied with increasing interest: chronic low-grade inflammation as a possible cause of infertility.

Within this context, a key concept appears: the inflammasome, and understanding it can change the way we understand fertility.

When we talk about infertility, we usually think only about hormones, irregular cycles, or sperm quality. However, infertility is recognized as a disease of the reproductive system, both female and male, and it is diagnosed when, after one year of frequent sexual intercourse without contraception, pregnancy is not achieved. Behind that diagnosis there is almost never a single cause; rather, it is the result of multiple factors that interact with each other.

Age is one of the most well-known elements. From the age of 30, female fertility begins to progressively decline due to ovarian aging and the reduction in egg quality. But age is not everything. The environment also influences it: chronic stress, exposure to pollutants, the consumption of toxic substances, and even mood disorders can alter hormonal balance and affect reproductive function.

Sexually transmitted infections represent another important factor, since they can cause damage and persistent inflammation in the reproductive organs. To this are added conditions such as endometriosis, PCOS (polycystic ovary syndrome), premature ovarian aging, or recurrent miscarriage. Although they appear to be different diagnoses, they share a common denominator: in all of them inflammation plays a relevant role.

There are different types of inflammasomes, but one of the most studied is NLRP3. When its activation is adequate, it contributes to the body’s defense. However, if it becomes excessively activated or dysregulated, it can trigger a disproportionate inflammatory cascade.

This type of imbalance has been associated with various inflammatory diseases that directly affect fertility. For this reason, it is necessary to pay attention beyond the common factors, to factors that influence fertility and can be improved in time. Understanding the role of the inflammasome and inflammatory processes allows us to broaden our perspective and address infertility from a different point of view, where caring for the cellular environment can become just as important as addressing hormonal and structural factors.
