Everything surrounding fertility (and infertility) continues to generate great interest in our society. However, there are still beliefs that, despite being far removed from medical reality, remain deeply rooted in the collective imagination. Some of them can create false expectations, while others may cause unnecessary concern.
In this context, it is essential to seek information from reliable sources, through specialized medical teams in assisted reproduction who are prepared to answer questions and provide accurate, evidence-based information. For this reason, we would like to compile some of the most common myths about fertility to help clarify doubts.
One of the most widespread myths is that only a woman’s fertility is affected by age. It is true that ovarian reserve and egg quality decline over time, especially after the age of 35, but a man’s age can also influence male fertility.
As the years go by, semen quality may decrease, with increased sperm DNA fragmentation and a higher risk of genetic alterations. Fertility is a matter of two, and age does not discriminate by sex.

Regular menstrual cycles are usually a good indicator that ovulation is occurring, but they do not guarantee the absence of difficulties in achieving pregnancy. Other factors may influence conception, such as subtle hormonal imbalances, tubal disorders, endometriosis or male factors that are not easily detected. Therefore, menstrual regularity is a positive sign, but not an absolute guarantee.
Stress is not a direct cause of infertility, although it can affect general well-being and how the reproductive process is experienced. Embryo implantation and fertilization are complex biological processes that are not compromised by a woman’s stress levels. Nevertheless, taking care of emotional health is important, especially when the attempt to conceive extends over time.
It is common to think that once pregnancy has been achieved, there should be no difficulties in achieving another one years later. However, in some cases what is known as secondary infertility occurs: difficulties in conceiving again after having previously been a mother. This may be due to hormonal changes, prior surgery, infections, alterations in semen quality or simply the passage of time.
Hormonal contraceptive methods do not cause permanent infertility. Once treatment is discontinued, the body usually regains its normal function. This process may take weeks or even months, but reproductive function does recover. If pregnancy does not occur after that time, the cause is usually related to pre-existing factors rather than contraceptive use.
Fertility (and infertility) does not depend solely on genetics or age. Lifestyle factors can play a significant role. Smoking, alcohol consumption, drug use, overweight or obesity, and an unhealthy diet can affect both egg and sperm quality. For this reason, adopting healthy habits before trying to conceive is important. Although this does not guarantee pregnancy, it does increase the chances.
Harmful habits such as smoking can impair fertility
It may seem uncommon, but the reality is that the World Health Organization (WHO) has warned that 1 in 6 people of reproductive age worldwide experience infertility at some point in their lives. These figures, combined with current lifestyle trends—such as delaying motherhood—confirm a growing reliance on assisted reproduction techniques to achieve pregnancy.
Phrases such as “relax and it will happen” are common when a woman or couple is trying to conceive, but they are not supported by scientific evidence. Emotional well-being is important, but stopping thinking about pregnancy does not solve underlying medical issues that need to be investigated and, if necessary, treated. Moreover, these messages can generate unnecessary guilt or frustration in those who have been trying to conceive for a long time.
Fertility is not a simple issue, nor can it be explained through clichés or popular beliefs. Having reliable information is the first step toward making informed decisions and avoiding unnecessary fears.
