State of the art and emerging drug therapies for female infertility.

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.

Progesterone for preparation of the endometrium for frozen-thawed blastocyst transfer in vitro fertilization cycles: a prospective study on patients' opinions on a new subcutaneous formulation.

We aimed to evaluate patients' perspectives on a progesterone subcutaneous formulation for endometrial preparation for frozen-thawed blastocyst transfer. In this prospective study, women with at least one experience with vaginal progesterone, undergone endometrial preparation with oral estradiol valerate and daily subcutaneous progesterone administered from the fifth day before the transfer until the day of the beta-hCG test. Patients completed three questionnaires, at enrollment (Q1), for gathering information on the experience with vaginal treatment and expectations about the subcutaneous route and then at the time of the transfer (Q2) and eight days later (Q3). Main outcome measures were patients' opinions on comfort, ease of use, convenience, overall satisfaction, level of anxiety and pain associated with the administration of subcutaneous progesterone in comparison with their previous experience. Sixty-nine women completed the questionnaires. All vaginal versus subcutaneous comparisons were significantly in favor of the subcutaneous route. When comparing patients' expectations at Q1 with patients' opinions at Q2 and Q3, all evaluations, except for one, demonstrated that the patient's positive expectation was confirmed after 5 and 13 days of treatment. In conclusion, in women with previous experience with vaginal progesterone, the subcutaneous route was associated with significantly increased acceptance.

Endometriosis shows no impact on the euploid blastocyst rate per cohort of inseminated metaphase-II oocytes: A case-control study.

OBJECTIVE: To evaluate the true impact of endometriosis on oocytes' competence defined as blastulation, euploidy and implantation rates. DESIGN: Retrospective multicenter case-control study involving infertile couples undergoing ICSI with qPCR and trophectoderm biopsy-based PGT-A. Patients affected from endometriosis (n = 210) were diagnosed through transvaginal sonography or surgical history with histological confirmation. Each case was matched to two controls (n = 420) according to IVF clinic, maternal age at retrieval (38.6 ± 2.7 yr), number of previous failed IVF treatments (0.5 ± 0.8) and number of metaphase-II oocytes retrieved (6.1 ± 3.7 per patient). The primary outcome was the mean euploid blastocyst rate per cohort of inseminated metaphase-II oocytes. Other embryological, clinical, obstetric and neonatal outcomes were also evaluated. RESULTS: The mean euploid blastocyst rate per cohort of inseminated metaphase-II oocytes was identical in the two groups (18 %±22 %) independently of maternal age. No difference was shown for all embryological outcomes investigated. The live birth rates per vitrified-warmed single euploid blastocyst transfer were also similar (67/158, 42 % in patients affected from endometriosis versus 132/327, 40 % in matched-controls). No difference was reported in the gestational and neonatal outcomes. The cumulative live birth delivery rates among completed cycles were also identical (61/201, 30 % versus 117/391, 30 % in endometriosis and matched-control groups, respectively) independently of maternal age. CONCLUSIONS: Endometriosis might not impair oocyte developmental and reproductive competence, although its potential impact on the number of metaphase-II oocytes retrieved cannot be ignored. This information is critical for clinicians during counseling to outline an effective strategy to treat infertile patients affected from this condition. Future prospective studies are needed to evaluate the impact of endometriosis stage on euploidy rates.

Influence of COVID-19 pandemic on the psychological status of infertile couples.

OBJECTIVE(S): to evaluate the impact of the COVID-19 pandemic on infertile couples' emotions, anxiety and future plans. STUDY DESIGN: An observational study was perfomed by Italian ART centers and online forums. In this study, infertile couples candidate to ART and whose treatment was blocked due to the COVID-19 lockdown were enrolled through an online survey. The psychological impact of COVID-19 was measured by Impact of Event Scale-Revised (IES-R) and by a short form of the Spielberger State-Trait Anxiety Inventory (STAI); Self-perceived anxiety related either to pregnancy safety and to economic crisis measured by VAS scale. RESULTS: 627 patients completed the survey. The COVID-19 lock-down had a moderate/severe psychological impact on infertile patients (mean IES-R score 36.4 ± 16.6). The mean STAI score was 49.8 ± 15.3, with an overall incidence of STAI > 36 of 71 %. The mean VAS scale for anxiety perception was 45.3 ± 15.3. Women were more emotionally distressed, anxious and depressed than men (36.8 ± 16.4 vs 31.0 ± 18.4 for IES-R, respectively; p = 0.03). Notwithstanding the uncertainty about pregnancy safety, 64.6 % of respondents chose to maintain their reproductive programme. Economic crisis induced 11.5 % of the surveyed patients to give up their ART program. Respondents who had at least one relative affected by COVID-19 had a significantly higher IES-R score and anxiety VAS, but not higher STAI scores, than patients belonging to unaffected families. CONCLUSION(S): COVID-19 pandemic itself and the recommendation to stop ART program generated higher distress levels in infertile couples. The psychological impact of COVID-19 pandemic in infertility patients should not be underestimated, and a specific psychological support should be planned.
