A new study reveals that cryopreserving egg cells may reduce a woman’s chances of becoming a mother. Cryopreservation may damage the egg cells. To be more precise, this means that the chances of having a successful birth may be decreased by freezing egg cells in order to delay motherhood.
At the moment, this option is being taken into consideration by many women, it is occurring worldwide and it is recommended by some scientific circles.
Many fertility experts agree with the cryopreservation process and encourage women to make use of it, provided they want to become mothers later in life, as younger egg cells are believed to be healthier.
Moreover, even Google and Apple promote this option, as they want to boost women’s chances of pursuing their careers. They offered to pay their female workforce to do so.
A newly developed study contradicts the above concept. The freezing or thawing procedure might damage the eggs and could decrease a woman’s chances of experiencing motherhood.
A team of US researchers from the Center of Human Reproduction in New York analyzed a 2013-issued study conducted on data belonging to 8 fertility clinics. They examined 93 percent of all donor in vitro fertilization cycles that were performed in these clinics.
This particular scientific team’s findings are surprising when compared to widespread, previous beliefs. They revealed that women have a 56 percent chance of becoming mothers with fresh ova, but only 47 percent with frozen egg cells.
This means that a possibility would be that nine in 100 women recurring to in vitro fertilization via cryopreservation might not become mothers because of issues in the freezing process.
As the data was anonymous, their discovery should be treated with caution because they could not manipulate their findings to the age of the mother or her infertility diagnosis.
Their message is that, nevertheless, women should be aware of the possible implications of the egg cryopreservation technique and they should be warned that recurring to this method could decrease their pregnancy chances.
Unlike postponing fertility for social reasons, Dr. Vitaly Kushnir, lead author of the study, said that it is justifiable that women freeze their eggs “due to impeding exposure to chemotherapy to treat cancer, which can destroy the ovarian reserve and future pregnancy potential.”
Some see the egg freezing process as advantageous in a female’s youth, as women are born with eggs that degenerate over time. However, the womb ages slowly, so an older woman can become pregnant even if she’s experienced menopause.
The study authors concluded that it is still unclear why frozen eggs would be less productive than fresh ones, so additional research is needed.
