Ovarian response to stimulation for fertility preservation in women with hematologic cancer

Abstract : Purpose: To compare the ovarian response to controlled ovarian hyperstimulation (COH) in patients with hematologic malignancies treated for fertility preservation (FP) and healthy subjects (oocyte donors (OD)). Patients and methods: Retrospective cohort study comparing 41 women (18-37 years) who underwent COH for oocyte vitrification prior to gonadotoxic treatment for hematologic cancer (FP group) from January 2014 to February 2019 and with 117 women undergoing COH as part of an OD protocol (OD group) during the same period. The number of frozen mature oocytes, number of oocytes retrieved, total dose of rFSH, maximal estradiol levels, percentage of maturity, number of dominant follicles >14 mm, days of stimulation were evaluated. Results were adjusted for age, body mass index (BMI), anti-Mullerian hormone (AMH) and rFSH starting dose. Results: Patients in the FP group were younger and had a lower BMI than those in the OD group. rFSH starting dose was higher in the FP group (median 225UI (125;450) vs 150UI (87.5;337.5), p < 0.0001). After adjusting for age, BMI and starting rFSH dose according to ANCOVA, more frozen mature oocytes (median 10 (0;45) vs 8 (0;22] p = 0.0055) and retrieved oocytes (median 12 (0;49) vs 11 (0;29) p = 0.0468) were found in the FP group. Other outcome measures did not differ between the groups. Conclusion: Ovarian response after COH in women with a hematologic cancer is similar to that in the general population. A higher number of mature oocytes were collected in the FP group after strong COH.
