The influence of the environment on fertility and the effectiveness of IVF

Scientific research increasingly confirms that environmental factors play a crucial role in human reproductive health. A polluted environment can cause hormonal disorders, genetic mutations, and significantly reduce the quality of sex cells. This phenomenon is particularly visible in industrialized regions, where the levels of harmful substances in the air, water, and soil often exceed acceptable health standards.

Ecology and Reproductive Function

Fertility is an essential aspect of reproductive health, which depends not only on the state of the organism and lifestyle but also on the quality of the environment. Pollution by toxic substances such as pesticides, heavy metals, industrial emissions, and petroleum-derived products has a significant negative impact on the reproductive system of both men and women.

By entering the air, drinking water, and food, these harmful compounds disrupt reproductive processes: in men, they reduce the mobility and quality of sperm, while in women, they cause ovulation disorders and deteriorate the condition of the endometrium. Substances capable of interfering with the functioning of the endocrine system are the most dangerous. They can mimic or block the action of sex hormones, disrupting folliculogenesis and ovulation, thereby reducing the chances of conception.

Particular attention must be paid to the risk of genetic mutations caused by prolonged exposure to heavy metals and other toxic compounds. These changes not only make pregnancy more difficult but can also be passed on to future generations.

Environmental Factors and IVF Outcomes

In vitro fertilization (IVF) is a complex medical procedure whose effectiveness directly depends on the health status of patients and external conditions, including the environment. To achieve optimal results, it is necessary to obtain high-quality eggs and sperm, as well as a favorable environment for embryo development.

Modern scientific data show that exposure to environmental toxins such as phthalates, pesticides, heavy metals, and volatile organic compounds can significantly reduce the chances of IVF success. These substances disrupt hormonal balance, deteriorate the quality of sex cells, and affect embryo implantation.

In particular, a French study conducted at the University Hospital of Bordeaux demonstrated the negative effect of ozone (O₃) on clinical pregnancies after IVF, as well as the impact of air pollution caused by biomass combustion (source). Another French study noted that increased exposure to nitrogen dioxide (NO₂) and fine particulate matter (PM10) during the folliculogenesis phase is associated with a deterioration in embryo quality (source).

The mechanism of action of environmental pollutants lies in their ability to mimic hormones, interfering with the natural biochemical processes of the body. This complicates the control of ovulation stimulation, reduces the quality of obtained embryos, and increases the risk of procedure failure.

Practical Recommendations

Given the high sensitivity of the reproductive system to environmental influences, especially in the context of IVF, it is recommended that physicians thoroughly collect patients’ environmental histories. It is also important to minimize the influence of harmful factors: use water filters, choose eco-friendly products, avoid prolonged stays in polluted areas, and limit contact with household chemicals.

A conscious attitude towards environmental risks and the measures taken to reduce them can significantly increase the chances of conceiving and giving birth to a healthy child, particularly when using assisted reproductive techniques.

Thus, ecology is an indispensable element of comprehensive diagnosis and preparation for infertility treatment, and its importance in IVF programs should not be underestimated.
