Outcomes of Social Egg Freezing: A Cohort Study and a Comprehensive Literature Review

No guarantees: planned oocyte cryopreservation, not quite an insurance policy

Planned oocyte cryopreservation (OC) has the potential to address the burden of the biological clock, giving women and individuals with ovaries more autonomy in choosing when to have children and with whom. In the United States, the annual number of OC cycles has grown significantly, yet many questions remain regarding planned OC. The field is starting to gather data on the clinical practice and social perspectives around planned oocyte cryopreservation, including the optimal age range at which to offer planned OC, what factors are most predictive of a successful outcome, and the optimal number of oocytes and ovarian stimulation cycles to achieve a live birth. There is a clear need for setting realistic expectations about the chance of success with OC; however, most patients have yet to return to thaw their oocytes, and outcomes data are limited. Clinical models have been developed to predict OC success based on surrogate markers such as age, number of oocytes retrieved, and anti-Müllerian hormone level. Patient education should emphasize the age-related decline in fertility, that eggs do not equal embryos, and that more than one cycle may be needed to obtain sufficient oocytes to have a reasonable chance of future success. While planned OC is not quite an insurance policy against future reproductive challenges, it provides the best option to date for expanding the reproductive window and maximizing reproductive options while navigating individual life circumstances in the context of family building.

Risk-reducing salpingectomy with delayed oophorectomy to prevent ovarian cancer in women with an increased inherited risk: insights into an alternative strategy

Epithelial ovarian cancer (EOC) is the most lethal type of gynaecological cancer, due to lack of effective screening possibilities and because the disease tends to metastasize before onset of symptoms. Women with an increased inherited risk for EOC are advised to undergo a risk-reducing salpingo-oophorectomy (RRSO), which decreases their EOC risk by 96% when performed within guideline ages. However, it also induces premature menopause, which has harmful consequences. There is compelling evidence that the majority of EOCs originate in the fallopian tube. Therefore, a risk-reducing salpingectomy with delayed oophorectomy (RRS with DO) has gained interest as an alternative strategy. Previous studies have shown that this alternative strategy has a positive effect on menopause-related quality of life and sexual health when compared to the standard RRSO. It is hypothesized that the alternative strategy is non-inferior to the standard RRSO with respect to oncological safety (EOC incidence). Three prospective studies are currently including patients to compare the safety and/or quality of life of the two distinct strategies. In this article we discuss the background, opportunities, and challenges of the current and alternative strategy.

Social Egg Freezing-A Trend or Modern Reality?

INTRODUCTION

Egg freezing for social reasons is a process in which women who want to preserve their ability to fertilize their own oocytes at an older age freeze their eggs. With the help of in vitro fertilization, the cryopreservation of oocytes for future use is achieved. The aim of this article is to study the reasons, the risks and the effectiveness of the method from a worldwide aspect.

METHODS

A literature search was conducted to evaluate pertinent studies, using data from the search engines PubMed, Google and UptoDate as well as the medical literature.

RESULTS

The reasons for delayed procreation are non-medical, with the lack of an appropriate partner for a family being first on the list. The success rate of this method differs with the age of the woman, the number of fertilized eggs and other factors. Like every medical procedure, this method carries risks that relate to the mother (being of advanced age), the embryo and the procedure of in vitro fertilization. The policies that apply in each country differ depending on respective social, economic, religious and cultural factors. Due to the high cost of the method, its selection remains a choice for only a few, reinforcing social inequality. The question of the medicalization of reproduction remains unanswered in the industry of assisted reproduction.

CONCLUSIONS

In conclusion, egg freezing for social reasons is gradually becoming more widely known, with the United States of America and Israel being at the top the list. Unfortunately, there is no official data registry, and consequently, no statistical results are yet available for Greece, even though it is a method that more and more women are considering. Nevertheless, there is an imperative need for a universal legal framework for all countries with respect for the needs of every woman and different social conditions. More research and data from the literature are needed in relation to the effectiveness of the method from moral and social perspectives.
