RESUMEN
Mitochondria are known to play a key role in the regulation of reproductive capacity. Senescence is known to impair mitochondrial function and, ultimately, cellular energetic metabolism. Therefore, as women age, a deficient energy supply is likely to affect oocyte quality. The analysis of granulosa cells is considered a valuable noninvasive strategy to assess factors implicated in oocyte competence. Thus, we conducted an observational prospective cohort to evaluate the impact of aging on energy production by luteinized granulosa cells (LGCs). The control group comprised 13 young oocyte donors, whereas the comparison group included 13 infertile women over 38 years of age undergoing in vitro fertilization. Women with diseases that could potentially impact mitochondrial function were excluded. No differences were detected in the ATP levels in LGCs from young donors and infertile patients of advanced reproductive age (1.9 ± 0.99 picomoles in the control group vs. 2.1 ± 0.59 picomoles; p-value = .139). Likewise, the ATP levels in our series did not correlate with either oocyte number or maturity. Despite the similar ATP levels in LGCs, an age effect on the bioenergetic status cannot be excluded. Energy metabolism is very complex, and ATP does not seem to be the most important and reliable parameter.

AIM: 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). MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

OBJECTIVE: To evaluate the hormonal profile, antral follicle count (AFC) and ovarian response of patients with hypogonadotropic hypogonadism (HH). DESIGN: Observational retrospective cohort including infertile women with HH undergoing assisted reproductive treatment (ART). SETTING: University-affiliated infertility center. PATIENT(S): Thirty-three women with HH who underwent ART between January 2007 and September 2018. The control group comprised 66 age-matched counterparts with tubal or male factor infertility. The patients with an abnormal karyotype, and those presenting primary or secondary amenorrhea due to other causes, were cautiously excluded. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The primary outcome was serum levels of anti-Müllerian hormone (AMH) and AFC. We also investigated whether HH impacts ovarian response and reproductive outcomes. RESULT(S): Although AFC was similar between groups, HH patients showed significantly higher AMH levels (4.6 ± 2.7 ng/mL vs. 3.0 ± 1.9, p = 0.010) and lower basal FSH and LH. While the HH group needed longer stimulation [13 days (11-26) vs. 10 (7-14), p < 0.001] and higher gonadotropin doses [2700 IU (825-6300) vs. 2100 (425-5000), p = 0.038 ], no significant differences were detected in either the number or maturity of retrieved oocytes, or in the fertilization rate, number of embryos transferred, implantation rate, clinical pregnancy rate and live birth rate per cycle. CONCLUSION(S): HH patients present higher AMH levels, but similar AFC. Despite requiring longer stimulation and higher gonadotropin doses, ovarian response and reproductive outcomes seem unaffected.

PURPOSE OF REVIEW: Surgery has traditionally been the primary treatment option for endometriosis-related infertility of any phenotype. However, advances and refinements of assisted reproductive technologies (ART) permit a more conservative approach in many scenarios. This review summarizes the latest findings in the field of reproductive medicine, which have supported a paradigm shift towards more conservative management of ovarian endometrioma. RECENT FINDINGS: The presence of ovarian endometrioma per se is likely to impair ovarian reserve and alter ovarian functional anatomy. Conventional laparoscopic surgery is associated with significant risk of additional damage, and less invasive treatment approaches require further evaluation. With regard to infertile women with ovarian endometrioma who are scheduled for ART treatment, current data indicate that prior surgical intervention does not improve ART outcomes, and that controlled ovarian hyperstimulation (COH) does not affect quality of life or pain symptoms. SUMMARY: Reproductive medicine physicians frequently encounter patients with ovarian endometrioma. The current evidence does not support the postponement of infertility treatment in favour of surgery, except in cases with severe symptoms or to improve follicle accessibility. Although these patients may exhibit diminished ovarian response to COH, their endometrial receptivity, aneuploidy rates, and fertility outcomes are similar to healthy controls. Surgery for ovarian endometrioma provides no benefits in ART treatments.

La edad en la que las mujeres comienzan a buscar su primer embarazo se ha venido retrasando en las sociedades desarrolladas. Este retraso tiene como consecuencia una disminución de la fecundabilidad materna, pues a partir de los 35 años comienza a disminuir y lo hace en una forma muy significativa a partir de los 40 años. En esta revisión se hace un recuento de la estimulación ovárica en usuarias mayores de 38 años.
Age when women start looking to have their first pregnancy is being postponed in developed societies. This delay results in reduction in maternal fecundability that starts at age 35 and is significant at age 40 and over. In this review we recount ovarian stimulation in women over 38 years.
