Objective: The objective of this study was to report on the profile of patients who underwent oocytes and semen freezing in a private Human Reproduction clinic and indicate what was the most common motivation for cryopreservation.
Methods: The data used in this study is from anamnesis/clinical sheet and medical records of patients who performed cryopreservation between April 2020 to June 2025 in a private Human Reproduction clinic in Brazil. Two terms were used to classify a motivation for cryopreservation: the term “medical reasons” refers to the presence of medical advice in the decision to cryopreserve the genetic material such as a diagnosis of some pathology. The term "social/elective" refers to preventative treatment not related to medical diagnosis. The sum (total), average (mean), standard deviation (sd) and percentage were performed in Microsoft Excel. The racial classification nomenclature was adopted in accordance with the ethno-racial and skin color category used by the Brazilian Institute of Geography and Statistics (IBGE).
Results: As a result, 75 patients underwent gamete freezing, being: 50 female patients and 25 male patients. The study found that the average age of female patients was 36.5 (sdą4.4) years old, 94% were university educated, 70% were single marital status, 52% females were identified as white and 48% as “parda”. 85% oocyte cryopreservation was for social reasons such as postponing motherhood and 15% for medical reasons (oncology patients). For male patients the average age was 40.4 (sdą13.8) years old, 40% were single marital status, 24% identified as white, 12% as “pardo” and 64% did not declare ethnicity nor their education. Of the seminal cryopreservation, 44% was for social reasons, 32% oncology patients and 24% to perform In vitro fertilization (IVF).
Conclusion: In conclusion, the majority of patients who undergo elective cryopreservation were for social reasons, mainly women without a partner. Furthermore, the data shows that the majority of patients froze their gametes when they were > 35 years old. Considering the adverse effect of reproductive aging on fertility, widely well documented, the findings suggest that there is a need to increase awareness and education at earlier ages so men and women can make informed decisions regarding their reproductive health and may help to avoid future infertility.
