It's been a hot topic for years - are fresh eggs more likely to lead to pregnancy than frozen eggs?

If you search the internet for information on fresh and frozen eggs and what is the best option for IVF, you will end up scratching your head. There is a lot of conflicting advice and medical information out there. Some experts say frozen is better, others strongly disagree. Below we will analyze the two cases.

What is egg freezing?


Egg freezing begins with the woman undergoing IVF (daily injections to stimulate the ovaries to produce many egg-containing follicles) and then egg collection (usually under mild sedation). The mature eggs are then obtained 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, for example at five years old. However, if you want to have a baby now, using fresh eggs is better than frozen eggs.


Who should consider egg freezing?

Those who are going to receive medical treatment that may affect their fertility Those who have a high-risk job (eg the Armed Forces) that could lead to injury, those who are going to be treated for a disease that may affect fertility those who are about to undergo surgery or have sex-changing drugs,
those who do not want or can not start a family at the moment, but want to freeze their eggs, to give an extension to the years of childbearing.


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 that remain in their ovaries deteriorates.

How long can eggs remain frozen?

The world record for the use of frozen sperm to start a family is currently at TFP GCRM ​​Fertility. This sperm was frozen in liquid nitrogen over 27 years earlier, before the gentleman was treated for cancer as a teenager. This frozen sperm was used then 27 years later, when she had a partner and was about to have children. Similarly, there is no biological reason why eggs cannot be stored indefinitely.

The association of IVF drugs with cancer risk is a major concern for women enrolled in these programs. But the plethora of bibliographic reports collected from credible scientific studies and published in reputable medical journals worldwide are reassuring and do not confirm this concern.

Of course not. In about a third of cases, infertility is due to the woman (female factor), while in a third of cases, it is due to the man (male factor). The remaining one-third is due to both (both men and women) or even to unknown factors.

The quantity and quality of a man's sperm can be affected by his health and lifestyle. Some factors that can reduce the quantity and / or quality of sperm are:

  • the alcohol
  • drugs
  • environmental toxins, including pesticides and lead
  • smoking
  • health problems
  • medicines
  • radiotherapy and chemotherapy
  • the age

Success rates vary at each IVF Center. Very important factors are also the age of the woman, the levels of her hormones and of course the sperm of the husband. Rates generally range from 45% or slightly higher for women up to 35 years old.

Infertility is defined as the failure to conceive after one year (or 6 months, if it is a woman over 35) with normal, regular sexual intercourse. In other words, when a year passes without the woman becoming pregnant, the couple should consult their doctor to determine the cause of the pregnancy and then treat it. We must all, however, be aware and not forget that the age factor is the most critical for female fertility and that the individualized approach of each couple is the "golden key" that solves the problem.

The number of treatment cycles a woman can undergo is not specified. It is certain that in our country there are high level obstetricians-gynecologists and organized infertility treatment centers, which offer impeccable medical services at this level. If there are correct indications (eg ovaries that respond to stimulation therapy, good quality endometrium, etc.) the success rate -especially with the use of newer techniques and biotechnological drugs, which show increased bioactivity compared to conventional drugs from urine- totals approximately 65%-70% after 4 cycles of treatment.

At the Center for Reproductive Medicine of Dr. Traianos we offer egg / sperm cryopreservation services for those who have a personal or medical reason and need this service. We use the most modern vitrification technique in the freezing of sperm and eggs.

The collection of eggs takes 10-15 minutes, it is not painful, it is done under intoxication and after the end of the process you return to your activities.

In general, experts agree that the fact that a couple has already had a child can be considered evidence that there is no infertility problem in the first place. It is like a small test that has been done and proves that they "succeeded" at least once. On the other hand, we need to know that in the meantime things may have changed and a problem may have arisen (eg the man may have had some inflammation that affects the quality of his sperm or has mediated something that affects female fertility: an inflammation, a gynecological surgery, an abortion, etc.). In any case, if a reasonable period of time (one year) passes and a couple can not achieve a pregnancy, then he should with the help of his doctor investigate if there has been a problem that causes infertility.
