The expected live-birth rate with FP indicated that one in three oncofertility patients would not expect to have a live birth following oocyte retrieval and embryo cryopreservation. While the decision trees were useful as decision-making tools for women contemplating FP, in the context of the current restrictions on oocyte donation and the extremely small number of adoptions in Japan, the remaining options for fertility after cancer are limited. In order for cancer survivors to feel secure in their decisions, the decision tree may need to be adapted simultaneously with improvements to the social environment, such as greater support for adoption.
Highlight The primary disease and patient's age varied in FP for children and adolescents. New patient selection criteria for OTC will be needed accordance with development of technology. Revised patient selection criteria might be appropriate in a short observation period.
The use of poly (ADP-ribose) polymerase (PARP) inhibitors is expected to increase, but their effect on fertility is still unclear. The aim of this study was to investigate the effect of PARP inhibitors on ovarian function. In an in vitro study, cultures of ovaries and granulosa cells (GCs) exposed to the PARP inhibitor olaparib were evaluated by real-time RT-PCR, histological study, and hormone assays. In an in vivo study, mice were administered olaparib orally and evaluated via in vitro fertilization (IVF), follicle count, immunohistochemical staining, and real-time RT-PCR. In vitro, the gene expression of GC markers decreased in the olaparib-treated group. Olaparib also negatively affected estradiol production and the expression of GC markers in cultured GCs, with abnormal morphology of GCs observed in the treated group. The follicle number indicated depletion of follicles due to atretic changes in the treatment group, both in vitro and in vivo. Also, olaparib reduced the number of retrieved oocytes and the fertilization rate of IVF, but they recovered after 3 weeks of cessation. Our results indicate that olaparib is toxic to ovaries.
In vitro fertilization (IVF) is a hallmark of reproductive medicine. However, the inconclusive outcome leads to marital disharmonies; thus, the choices of gamete donation and surrogacy (GD/S) are often offered. In restricted countries, the child-rearing choice through foster/adoption care is promising, but the uptake remains low. We explore the current reproductive services and adoption scenarios in Asian countries to delineate this issue. The web and literature search using PubMed and Ichushi was conducted in Japanese and English using the keywords “adoption”, “foster care”, “reproductive medicine”, including the interview with the respective Asian clinicians. We found that an established adoption system was seen in China, Malaysia, and the Philippines, mainly due to the restriction of GD/S. Although GD/S were allowed in Thailand, Singapore, and India, the different local affordability of IVF cost led to various adoption system scenarios. Nevertheless, the country’s economic aspect does influence the establishment of adoption care, mainly due to financial support from local government. Otherwise, the significant barrier was the cultural/religious background leading to low adoption rates. We concluded that the adoption option should always be highlighted as an alternative strategy as it synergistically contributes to children’s and infertile couples’ welfare.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
