Fertility preservation (FP) for hematological malignancies is difficult because immediate chemotherapy is needed after diagnosis. We report two cases of acute myeloid leukemia (AML) treated with controlled ovarian stimulation (COS) and oocyte cryopreservation using DuoStim after first-line chemotherapy. In Cases 1 and 2, COS and oocyte retrieval (OR) were performed using DuoStim 116 and 51 days after first-line chemotherapy, respectively, and 14 and 6 unfertilized oocytes, respectively, were cryopreserved. Another round of COS and OR was performed using the random-start method 82 days after first-line chemotherapy, and 22 unfertilized oocytes were cryopreserved. DuoStim is useful to maximize OR for patients with a short interval for FP. Many oocytes can be retrieved depending on the timing of recruitment from primary to secondary follicles, although ovarian reserve capacity declines immediately after first-line chemotherapy. Aggressive FP should be performed before allogeneic hematopoietic stem cell transplantation becomes necessary. [ABSTRACT FROM AUTHOR]

To evaluate the overall performance and oocyte quality of follicular phase stimulation (FPS) vs. luteal phase stimulation (LPS) among patients undergoing double ovarian stimulation (DuoStim). Observational retrospective two-center cohort study including 79 infertile women who underwent a total of 87 DuoStim cycles between January 2017 and May 2019. Besides assessing baseline characteristics in order to determine the patients' clinical profile, we analyzed the FPS and LPS regarding the total dose of gonadotropin received, the duration of stimulation, the number and maturity of oocytes, fertilization and blastocyst formation rates, and the number of blastocysts obtained. The patients' baseline characteristics were compatible with a diminished ovarian reserve and poor reproductive prognosis. While the luteal phase needed longer stimulation (12 days (5–19) vs. 11 (7–16), p <.001) and slightly higher gonadotropin doses (2946 ± 890 IU vs. 2550 ± 970 IU, p <.001), no significant differences were detected in the oocyte maturity, fertilization, and blastocyst formation rates. However, the number of oocytes retrieved (5 (0–16) vs. 4 (0–15), p =.006), mature oocytes (4 (0–15) vs. 3 (0–11), p =.032), and blastocysts obtained (70 vs. 53) were substantially greater after LPS. The DuoStim strategy in poor prognosis patients increases the number of oocytes and blastocysts available. Moreover, the number of oocytes and blastocysts obtained are higher after LPS when compared to FPS. Thus, it should be considered for selected patients in order to not only improve reproductive outcomes but also shorten the time to pregnancy. [ABSTRACT FROM AUTHOR]

At present, infertility is a key-issue. When applicable, in vitro fertilization (IVF) has become the standard approach to treat this condition but a thorough investigation and, whenever possible, the individual diagnosis of the underlying causes of infertility are required. For many female causes, indeed, efficient medical therapies are available to achieve a fast solution of the problem. This review is based on the relevant literature indexed in PubMed and SCOPUS and is focused on the most recent clinical literature on the treatment of women (and couples) affected from infertility. The reduction in IVF treatment burden and risks are now considered pivotal to set 'patient-friendly' therapies and represent crucial issues for both patients and physicians. To this end, the researchers are now focusing their attention on old drugs with new indications and new compounds with more appropriate functions, to improve the compliance of the women and reduce the burden of infertility, a condition that is becoming an important issue in the modern world, also for the Public Health System.
