It has been a hot debate for years — are fresh eggs more likely to lead to a pregnancy than frozen eggs?

If you search the internet for evidence on fresh versus frozen eggs and which is the better option for IVF, you will end up scratching your head. There is a great deal of conflicting advice and medical information out there. Some experts say frozen is better; others disagree completely. Below we look at both cases.

What is egg freezing?

Egg freezing begins with the woman going through the IVF process (daily injections to stimulate the ovaries to produce multiple follicles containing eggs), followed by egg retrieval (usually performed under light sedation). The mature eggs are then collected and frozen in liquid nitrogen at -196 °C.

Will freezing my eggs give me a better chance than using fresh eggs in the future?

Freezing your eggs now is more likely to give you a better chance of having a baby than using fresh eggs in, for example, five years' time. However, if you want to have a baby now, using fresh eggs is better than using frozen eggs.

Who should consider egg freezing?

Those who are about to undergo medical care that may affect their fertility; those with a high-risk job (e.g. the Armed Forces) that could lead to injury; those who are about to receive treatment for an illness that may affect their fertility; those who are about to undergo surgery or take medication to change their sex;
and those who do not wish to, or cannot, start a family right now but want to freeze their eggs to extend their childbearing years.

When should eggs be frozen?

There is no perfect age, but the earlier the better, because as women get older the quality of the eggs remaining in their ovaries declines.

How long can eggs stay frozen?

The world record for using frozen sperm to start a family is currently held by TFP GCRM Fertility. That sperm had been frozen in liquid nitrogen more than 27 years earlier, before the man received cancer treatment as a teenager. The frozen sperm was then used 27 years later, when he had a partner and was ready to have children. Likewise, there is no biological reason why eggs cannot be stored indefinitely.

FREQUENTLY ASKED QUESTIONS

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.
