Vitamin D is best known for its contribution to bone health and the immune system. However, few people know how important a role it also plays in fertility – in both men and women.

HOW VITAMIN D IS LINKED TO REPRODUCTIVE FUNCTION

In women, adequate vitamin D levels have been associated with regular ovulation and higher chances of successful embryo implantation. In conditions such as polycystic ovary syndrome (PCOS), low levels can worsen the symptoms and make conception even more difficult. In men, vitamin D is associated with better sperm quality -that is, improved motility and morphology- which increases the chances of fertilisation.

WHERE TO FIND VITAMIN D

Its most important source is the sun. A little daily exposure, mainly in the morning, is enough to switch on its natural production. You can also get it from foods such as:

oily fish (salmon, tuna)
eggs
fortified dairy products

Where levels are very low, your doctor may also recommend a supplement.

3 PRACTICAL TIPS

Don't avoid the sun: Even 10 minutes of natural light a day is beneficial.
Pay attention to your diet: Choose foods that support hormonal and reproductive balance.
Get tested: If you have been trying to conceive without success, check your vitamin D levels with a simple blood test.

Vitamin D does not work miracles, but it can be a crucial ally on the road to parenthood. Don't neglect its role - especially in the summer months, when it is easier to get.

Frequently Asked Questions most frequently.

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.
