Fertility preservation for social indications: a cost-based decision analysis

Human ovarian tissue cortex surrounding benign and malignant lesions

OBJECTIVE

To quantify the number of follicles in patients with ovarian pathologies, benign and malignant, in pregnant and nonpregnant states and to determine how the presence of ovarian masses and BRCA status affects follicular counts.

MATERIALS AND METHODS

Slides from 134 reproductive-aged women undergoing oophorectomy were examined using light microscopy by 3 independent counters blinded to the diagnosis. In all, 20 patients had cancer, 69 had benign conditions, and 35 patients were BRCA+ or had a strong family history of breast and/or ovarian cancer. In all, 10 women were either pregnant or immediately postpartum.

RESULTS

Patients undergoing risk-reducing surgery had significantly decreased follicle count compared to physiologic control. Patients with cancer had significantly decreased counts compared to all other groups. There were no differences within the benign cohort.

CONCLUSIONS

When compared to benign masses, the cortex surrounding an ovarian malignancy has decreased follicle density. The stretch impact may minimize any impact on total follicle numbers. Furthermore, there may be a proliferation of ovarian stroma, with the same number of follicles spread over a larger surface area. This information is important when counseling women with ovarian masses regarding the use of ovarian tissue cryopreservation.

Acceptable cost for the patient and society

Alongside the debate around clinical, scientific, and ethical aspects of assisted reproductive technology (ART), there exists a parallel debate around the economics of ART treatment and what is the most appropriate funding framework for providing safe, equitable, and cost-effective treatment. The cost of ART treatment from a patient perspective exhibits striking differences worldwide due to the costliness of underlying health care systems and the level of public and third-party subsidization. These relative cost differences affect not only who can afford to access ART treatment but how ART is practiced in terms of embryo transfer practices; in turn significantly impacting the health outcomes and costs of caring for ART conceived children. Although empirical evidence indicates that ART treatment is "good value money" from a societal and patient perspective, the challenge remains to communicate this to policy makers, primarily because fertility treatments are not easily accommodated by traditional health economic methods. Furthermore, with global demand for ART treatment likely to increase, it is important that future funding decisions are informed by what has been learned about how costs and economic incentives influence equity of access and clinical practice. In this review we provide an international perspective on the costs and consequences of ART and summarize key economic considerations from the perspective of ART patients, providers, and society as a whole in the coming decade.

[Social egg freezing: which problems?]

In today's society, many women push pregnancy further away from the "right" childbearing age. Assisted reproduction, except egg donation, is unable to fully overcome the effect of age on fertility loss. The effectiveness of oocyte vitrification is demonstrated, and oocyte vitrification is allowed in the French Bioethics law of 2011. In the French law, oocyte' s cryopreservation is proposed to oocyte donors without child. Social egg freezing for non-medical reason is already legal in some countries, but leads to new debates and discussions.

Is vitrification of oocytes useful for fertility preservation for age-related fertility decline and in cancer patients?

The aim of this review is to provide current knowledge on oocyte cryopreservation, with special emphasis on vitrification as a means to preserve fertility in different indications. Major advancements achieved in the past few years in the cryolaboratory have facilitated major changes in our practice. Areas such as fertility preservation for social or oncologic reasons, the possibility to create oocyte banks for egg donation programs, the opportunity to avoid ovarian hyperstimulation syndrome, or to accumulate oocytes in low-yield patients, or even to offer treatment segmentation by stimulating the ovaries, vitrifying, and then transferring in a natural cycle are some of the options that are now available with the development of cryopreservation. We present general experience from our group and others on fertility preservation for age-related fertility decline as well as in oncologic patients, confirming that oocyte vitrification is a standardized, simple, reproducible, and efficient option.

Concise review: fertility preservation: an update

Fertility preservation is an emerging field in medicine that enables men, women, and children to maintain reproductive health when it is threatened by gonadotoxic treatment. Patients affected by other nononcologic malignancies that can impair spermatogenesis and ovogenesis can also benefit from fertility preservation treatments. Age-related infertility can also be overcome by cryopreserving gametes or embryos. The only established methods for fertility preservation in male patients are sperm cryopreservation in postpubertal age and experimental testicular tissue cryopreservation in prepubertal age. In adult women, oocyte cryopreservation is the preferred option, whereas ovarian tissue cryopreservation is the only possibility for prepubertal girls. Fertility preservation treatments must be addressed through a multidisciplinary approach that involves gynecologists, urologists, oncologists, pediatricians, and professionals in the field of medically assisted reproduction to work in coordination to provide patients with counseling and comprehensive information about fertility issues.
