Conclusion

The changing seasons affect not only our mood and physical condition, but can also have a significant impact on fertility. Winter, with its low temperatures, reduced sunlight and changes in daily habits, is a period during which reproductive function in both men and women may change.

The effect of temperature on the reproductive system

The human body is particularly sensitive to extreme temperatures. In men, sperm production is affected by heat — however, the lower temperatures of winter appear to improve sperm quality and motility, as exposure to heat and physical fatigue is reduced.
In women, by contrast, cold can affect blood circulation and lead to hormonal fluctuations, affecting the ovulation cycle.

The importance of vitamin D

Vitamin D, also known as the "sunshine vitamin", plays a key role in regulating the hormones of the reproductive system. During the winter months, reduced sun exposure leads to lower vitamin D levels, which can affect egg quality and the proper implantation of the embryo.
Boosting it through diet or supplements is a simple and effective way of supporting fertility.

The role of mental well-being and stress

Winter is often associated with lower energy and seasonal low mood. Increased stress and a lack of natural light can affect the function of the hypothalamus, the brain centre that controls the production of hormones such as FSH and LH — which are crucial for fertility.
Managing stress through exercise, good sleep and gentle relaxing activities is particularly important at this time of year.

Diet and the immune system

During the winter, diet plays a key role in maintaining reproductive health. Foods rich in zinc, vitamins C and E and omega-3 fatty acids help to support hormonal balance and the proper function of the ovaries and testicles.
Adequate hydration, although often neglected in winter, is also important for the body to function well.

Seasonal data and IVF

Research shows that IVF cycles carried out in the winter months have comparable or even slightly higher success rates, possibly because of more stable temperatures and lower levels of oxidative stress. However, success always depends on an individually tailored protocol and on the overall care of the body.

Conclusion

Winter is not an obstacle to fertility; on the contrary, with the right preparation it can be a favourable time for those trying to conceive. Looking after the body, strengthening the immune system, a balanced diet and support for emotional well-being create ideal conditions for a successful attempt.

Infertility is defined as the failure to achieve conception after one year (or 6 months in the case of a woman over the age of 35) of normal, regular sexual intercourse. In other words, when a year has passed without the woman becoming pregnant, the couple should consult their treating physician, so that the cause preventing pregnancy can be identified and subsequently addressed. However, we should all be aware and not forget that age is the most critical factor for female fertility, and that an individualized approach to each couple is the "golden key" that solves the problem.

Of course not. In approximately one third of cases, infertility is due to the woman (female factor), while in another third of cases it is due to the man (male factor). In the remaining third, it is due to both partners (both the man and the woman) or even to unknown factors.

• alcohol • narcotic substances • environmental toxins, including pesticides and lead • smoking • health problems • medications • radiotherapy and chemotherapy • age

In general, specialists agree that the fact that a couple has already had a child may be considered evidence that, at least initially, there is no infertility problem. It is like a small test that has been carried out and shows that they “succeeded” at least once. On the other hand, however, we should be aware that circumstances may have changed in the meantime and that a problem may have developed (e.g., the man may have had an inflammation affecting the quality of his sperm, or something may have occurred that affects female fertility: an inflammation, gynecological surgery, an abortion, etc.). In any case, therefore, if a reasonable period of time (one year) passes and a couple is unable to achieve a pregnancy, then, with the help of their doctor, they should investigate whether a problem causing infertility has arisen.

Success rates vary at each IVF center. Very important factors also include the woman’s age, her hormone levels, and, of course, her husband’s sperm. In general, rates are around 45% or slightly higher for women up to 35 years of age.

The number of treatment cycles a woman may undergo is not fixed. It is certain that in our country there are highly qualified obstetrician-gynecologists and well-organized infertility treatment centers that provide excellent medical services in this field. Provided that the appropriate indications are present (e.g., ovaries that respond to stimulation treatment, a good-quality endometrium, etc.), the success rate—particularly with the use of newer techniques and biotechnological medicines, which demonstrate increased bioactivity compared with conventional urine-derived medicines—reaches a cumulative rate of approximately 65%–70% after 4 treatment cycles.

Egg retrieval takes 10–15 minutes, is not painful, is performed under sedation, and after the procedure is completed you can return to your activities.

The association between IVF medications and the risk of developing cancer is the greatest concern for women participating in these programs. However, numerous literature references gathered from reliable scientific studies and published in reputable medical journals worldwide are reassuring and do not confirm this concern.

At Dr. Traianos' Reproductive Medicine Center, we offer egg and sperm cryopreservation services for individuals who have a personal or medical reason and require this service. We use the most advanced vitrification technique for the freezing of sperm and eggs.
