PURPOSE: Failure to collect oocytes at the time of oocyte pick-up is an unfavorable outcome of in vitro fertilization (IVF) cycles. In these cases, prompt intrauterine insemination (IUI) could be an option (rescue IUI), but this possibility has been poorly studied. METHODS: Rescue IUI is routinely offered in our unit in women failing to retrieve oocytes, provided that they have at least one patent tube, normal male semen analysis, and the total number of developed follicles is ≤ 3. We therefore reviewed all oocyte retrievals performed from 2006 to 2022 in our unit to identify these cases. As a comparator, we referred to preplanned IUI performed during the same study period. The 95% confidence interval (95% CI) of proportions was calculated using a binomial distribution model. RESULTS: Rescue IUI was performed in 96 out of 3531 oocyte retrievals (2.7%; 95% CI 2.2-3.3%). Six live births were obtained, corresponding to 6.2% (95% CI 2.3-13.1). All pregnancies were singletons. CONCLUSIONS: Rescue IUI in women failing to retrieve oocytes is a possible option that may be considered in selected cases. The efficacy is low, but the procedure is simple, and without significant risks. Generalizability to a conventional IVF protocol setting is however limited.

The procedure of embryo transfer (ET) must be as gentle as possible since any traumatism may cause uterine contractility that interferes with the implantation. However, this ideal conduct is not always possible, and additional measures may be necessary (difficult ET). Different studies have evaluated the impact of difficult ET on the clinical pregnancy rate (CPR), but results were not univocal. The present systematic review and meta-analysis was aimed to provide a precise estimate of the possible detrimental effects of difficult ET on CPR. The study protocol was registered online (PROSPERO number: CRD42023387197). An electronic database search was performed to identify articles published until September 2022. The primary outcome was CPR. Fifteen studies fulfilled the inclusion criteria. Difficult ET significantly reduced the CPR (OR 0.70; 95%CI: 0.64-0.76; p < 0.0001. All pre-planned subgroup analyses according to study design (retrospective vs prospective studies), historical period (studies published before and after 2010), type of catheter, frequency of difficult cases (> or < 19%) and pregnancy rate (> or < 38%) confirmed the significant association. Difficult ET is associated with a significant reduction of CPR. Further studies are warranted to understand how to prevent or manage this common clinical situation.

The SARS-CoV-2 pandemic had a negative impact on the mental health of children and adolescents. Eight focus groups and six individual hearings were conducted to gain insights from the perspectives of 97 Italian professionals from a variety of disciplines, including child and adolescent neuropsychiatrists, pediatricians, general practitioners, social workers, psychologists, teachers, school deans, non-governmental organizations, and a researcher. Urban and rural settings were represented. The present research has been promoted by the Italian Independent Authority for Children and Adolescents (Autorità Garante per l'Infanzia e l'Adolescenza, AGIA) in collaboration with the National Institute of Health (Istituto Superiore di Sanità, ISS) and the Ministry of Education and its scientific value has been supervised by a Scientific Committee. The results of the focus groups' discussions revealed increased vulnerability, with the onset of new mental health disorders in healthy individuals and those in a condition of disadvantage, migratory contexts, and with disabilities. The already critical pre-pandemic structural and operational issues of existing services have been exacerbated. In healthcare, the activation of telemedicine has been a great asset but at the same time has generated challenges and critical issues that are still unresolved. Professionals emphasized the need to pay special attention to planning integrated responses aimed at overcoming inequalities and fragmentation. The result of this initiative translates into a set of operational recommendations useful for guiding investments and policies directed toward the protection of the mental health of minors in the health, educational, and social spheres from the outset.

PURPOSE: Random start protocols are commonly used for oocyte cryopreservation in women with cancer. However, albeit generally reassuring, available evidence is still insufficient to rule out a sub-optimal cycle outcome. This study aimed to compare follicular steroidogenesis between women initiating the random start protocol in the luteal phase and those initiating in the follicular phase. METHODS: Consecutive women with cancer scheduled for oocyte cryostorage were prospectively recruited. We excluded those requiring a concomitant letrozole assumption. All women received a standardized protocol with recombinant FSH and GnRH antagonists. At the time of oocyte retrieval, follicular fluids were pooled, and a sample was collected and frozen at -80 °C. All samples were assayed concomitantly after thawing by liquid chromatography-tandem mass spectrometry. The concentration of 15 different steroid hormones was determined. RESULTS: Seventy-one women were recruited. Thirty-three initiated the ovarian stimulation in the luteal phase, while the remaining 38 initiated in the follicular phase. Baseline characteristics were generally similar. Cycle outcome did also not differ; the median (interquartile range) number of frozen mature oocytes was 9 (5-14) and 10 (5-21), respectively (p = 0.42). None of the 15 tested steroid hormones differed. CONCLUSIONS: The endocrine microenvironment surrounding oocytes is not markedly influenced by the phase of the menstrual cycle at the initiation of ovarian stimulation. This result further supports the validity of random start protocols.

This study aims to evaluate the role of intraoperative transvaginal three-dimensional ultrasound (3DUS) during hysteroscopic metroplasty. This is a prospective cohort of consecutive patients with septate uterus undergoing hysteroscopic metroplasty with intraoperative transvaginal 3DUS guidance compared to a historical control group of patients undergoing hysteroscopic metroplasty without 3DUS. We conducted our research in a tertiary care university hospital in Rome, Italy. This study involved nineteen patients undergoing 3DUS-guided hysteroscopic metroplasty for recurrent abortion or infertility compared to 19 age-matched controls undergoing metroplasty without 3DUS guidance. During hysteroscopic metroplasty, 3DUS was performed in the study group when the operator considered the procedure to be completed, according to standards of operative hysteroscopy. If 3DUS diagnosed a residual septum, the procedure was continued until a 3DUS diagnosis of a normal fundus was obtained. The patients were followed with a 3DUS performed 3 months after the procedure. The numbers of complete resections (residual septum absent), suboptimal resections (measurable residual septum of less than 10 mm), and incomplete resections (residual septum > 10 mm) in the intraoperative 3DUS group were compared to the numbers in the control group with no intraoperative 3DUS. At follow-up, measurable residual septa were obtained in 0% of the patients in the 3DUS-guided group versus 26% in the control group (p = 0.04). Residual septa of > 10 mm were obtained in 0% of the 3DUS group versus 10.5% in the control group (p = 0.48). Intraoperative 3DUS reduces the incidence of suboptimal septal resections at hysteroscopic metroplasty.

The objective of this study is to determine whether dienogest therapy after endometriosis surgery reduces the risk of recurrence compared with placebo or alternative treatments (GnRH agonist, other progestins, and estro-progestins). The design used in this study is systematic review with meta-analysis. The data source includes PubMed and EMBASE searched up to March 2022. A systematic review and meta-analysis were performed in accordance with guidelines from the Cochrane Collaboration. Keywords such as "dienogest," "endometriosis surgery," "endometriosis treatment," and "endometriosis medical therapy" were used to identify relevant studies. The primary outcome was recurrence of endometriosis after surgery. The secondary outcome was pain recurrence. An additional analysis focused on comparing side effects between groups. Nine studies were eligible, including a total of 1668 patients. At primary analysis, dienogest significantly reduced the rate of cyst recurrence compared with placebo (p < 0.0001). In 191 patients, the rate of cyst recurrence comparing dienogest vs GnRHa was evaluated, but no statistically significant difference was reported. In the secondary analysis, a trend toward reduction of pain at 6 months was reported in patients treated with dienogest over placebo, with each study reporting a significantly higher reduction of pain after dienogest treatment. In terms of side effects, dienogest treatment compared with GnRHa significantly increased the rate of spotting (p = 0.0007) and weight gain (p = 0.03), but it was associated with a lower rate of hot flashes (p = 0.0006) and a trend to lower incidence of vaginal dryness. Dienogest is superior to placebo and similar to GnRHa in decreasing rate of recurrence after endometriosis surgery. A significantly higher reduction of pain after dienogest compared with placebo was reported in two separate studies, whereas a trend toward reduction of pain at 6 months was evident at meta-analysis. Dienogest treatment compared with GnRHa was associated with a lower rate of hot flashes and a trend to lower incidence of vaginal dryness.

Management options for ovarian endometriomas include expectant management, medical treatment, surgical treatment, in vitro fertilization (IVF), or a combination of the above. The choice of management depends on many clinical parameters that should be taken into consideration, the first of which is the main presenting symptom. Most patients are today referred to medical therapy as a first option in the case of associated pain, and to IVF in the case of associated infertility. When both symptoms are present, usually surgery is the preferred approach. Recently, however, surgical excision of an ovarian endometrioma has been associated with a postoperative reduction in the ovarian reserve, and recent guidelines suggest that the clinician should caution the patient as to the possible damage to the ovarian reserve in the case of surgery. However, evidence has been published as to a possible detrimental effect of the ovarian endometrioma on the ovarian reserve even if expectant management is followed. In this review, the current evidence on the conservative management of ovarian endometriomas, with particular focus on the issue of the ovarian reserve, is evaluated, and the different surgical techniques for the treatment of ovarian endometriomas are discussed.

The second-to-four digit ratio (2D:4D) has been proposed as a marker of prenatal hormonal exposure. It is suggested that prenatal exposure to androgens results in a shorter 2D:4D ratio, whereas a prenatal oestrogenic environment results in a longer one. In addition, previous research has shown an association between exposure to endocrine-disrupting chemicals and 2D:4D in animals and humans. On the endometriosis side, hypothetically, a longer 2D:4D ratio, reflecting a lower androgenic intrauterine milieu, could represent an indicator of the presence of the disease. In this light, we have designed a case-control study to compare 2D:4D measurements between women with and without endometriosis. Exclusion criteria included the presence of PCOS and previous trauma on the hand that could impact the measurement of the digit ratio. The 2D:4D ratio of the right hand was measured using a digital calliper. A total of 424 participants (endometriosis n = 212; controls n = 212) were recruited. The group of cases included 114 women with endometriomas and 98 patients with deep infiltrating endometriosis. The 2D:4D ratio was significantly higher in women with endometriosis compared to controls (p = 0.002). There is an association between a higher 2D:4D ratio and the presence of endometriosis. Our results support the hypothesis claiming potential influences of intrauterine hormonal and endocrine disruptors exposure on the onset of the disease.

PURPOSE: Heterozygous variants in PRRT2 are mostly associated with benign phenotypes, being the major genetic cause of benign familial infantile seizures (BFIS), as well as in paroxysmal disorders. We report two children from unrelated families with BFIS that evolved to encephalopathy related to status epilepticus during sleep (ESES). METHODS AND RESULTS: Two probands presented with focal motor seizures at 3 months of age, with a limited course. Both children presented, at around 5 years of age, with centro-temporal interictal epileptiform discharges with a source in the frontal operculum, markedly activated by sleep, and associated with stagnation on neuropsychological development. Whole-exome sequencing and co-segregation analysis revealed a frameshift mutation c.649dupC in the proline-rich transmembrane protein 2 (PRRT2) in both probands and all affected family members. CONCLUSION: The mechanism leading to epilepsy and the phenotypic variability of PRRT2 variants remain poorly understood. However, its wide cortical and subcortical expression, in particular in the thalamus, could partially explain both the focal EEG pattern and the evolution to ESES. No variants in the PRRT2 gene have been previously reported in patients with ESES. Due to the rarity of this phenotype, other possible causative cofactors are likely contributing to the more severe course of BFIS in our probands.

PURPOSE: The incidence of birth defects is increased in children born after assisted reproductive technologies (ART). However, changes in ART over time could influence this incidence. To investigate this issue, we present the frequency and trends of birth defects in ART and natural pregnancies in Lombardy, Northern Italy, during the period 2014-2020. METHODS: This is a population-based study using automated system of healthcare utilization (HCU) databases. ART pregnancies included only those obtained with conventional IVF or ICSI. After identifying the total number of deliveries, the rate of newborns with birth defects was compared between natural and ART pregnancies. A logistic regression model was used to calculate the adjusted odd ratio (OR). Analyses were repeated for every calendar year. RESULTS: Overall, 508,421 deliveries were identified, of which 14,067 (2.8%) were achieved after IVF-ICSI. A decreasing trend in birth defects over time was highlighted. The adjusted OR dropped from 1.40 (95%CI: 1.03-1.91) in 2014 to 0.92 (95%CI: 0.69-1.22) in 2020. During the study period, a significant reduction in multiple pregnancy and in the ratio of ICSI to conventional IVF was also observed, explaining at least in part the positive trend observed for birth defects. CONCLUSION: The increased risk of birth defects in children born after IVF-ICSI is not steady over time. A decline of this risk emerged in our region. Policy changes in ART may explain this beneficial effect.

RESEARCH QUESTION: The detrimental effects of endometriosis on IVF success are well known, but the underlying mechanisms are still uncertain. The objective of this study was to investigate the possible detrimental effects of the disease on ovarian response and embryo development. DESIGN: IVF cycles performed in the authors' unit between 2014 and 2020 were retrospectively reviewed. Women with a good ovarian reserve who underwent their first IVF cycle were included. A total of 248 women with endometriosis were identified and matched to 248 women without the disease, according to age, type of stimulation, anti-Müllerian hormone concentration and study period. The primary outcome was the number of women without good-quality embryos. Secondary outcomes included the rate of unexpected poor response (retrieval of ≤3 oocytes), the cumulative clinical pregnancy rate and the cumulative live birth rate. RESULTS: The number of women without good-quality embryos did not differ between women with endometriosis (exposed group) and those without it (unexposed group). The adjusted odds ratio was 0.85 (95% CI 0.51-1.44, P = 0.56). The clinical pregnancy rate and the live birth rate were also similar. Conversely, the rate of unexpected poor response was higher among women with endometriosis (23% versus 13%, P = 0.005). CONCLUSIONS: Overall, endometriosis does not markedly affect folliculogenesis and embryo development in the context of IVF. Only an increased risk of unexpected poor response emerged.

The incidence of cancer in reproductive-aged women is 7%, but, despite the increased number of cancer cases, advances in early diagnosis and treatment have raised the survival rate. Furthermore, in the last four decades, there has been a rising trend of delaying childbearing. There has been an increasing number of couples referred to Reproductive Medicine Centers for infertility problems after one partner has been treated for cancer. In these cases, the main cause of reduced fertility derives from treatments. In this review, we describe the effects and the risks of chemotherapy, radiotherapy, and surgery in women with cancer, and we will focus on available fertility preservation techniques and their efficacy in terms of success in pregnancy and live birth rates.

Random start protocols are commonly used for oocytes cryopreservation in women with cancer. However, evidence to support their effectiveness is yet modest. This study aims to compare the quality of ovarian response between the ovary carrying the dominant follicle or the corpus luteum (active ovary) and the contralateral ovary (resting ovary). Women with a diagnosis of malignancy who underwent oocytes cryopreservation were reviewed. The main inclusion criterion was the presence of a unilateral dominant follicle or a unilateral corpus luteum on the first day of ovarian hyperstimulation. The primary outcome was the number of mature oocytes retrieved. Intra-patient comparisons between the two ovaries were made using the nonparametric Wilcoxon test for paired data. Forty-three women were included. The number of mature oocytes retrieved from the active and the resting ovaries did not differ, the median [interquartile range-IQR] being 4 [2-7] and 5 [2-8], respectively (p = 0.09). The rate [IQR] of mature oocytes per developed follicle was 58% [40-80%] and 65% [33-87%], respectively (p = 0.42). In addition, no significant difference emerged when repeating the analyses separately for women carrying dominant follicles and for those carrying corpora lutea. This study failed to detect any detrimental effect of the presence of a dominant follicle or a corpus luteus on the ovarian response to hyperstimulation, thus supporting the validity of random start protocols.

In recent years, the introduction of advanced technologies has led to a new scientific revolution: the discovery of the human microbiota. Next-generation sequencing allowed the identification of microbial communities in all districts of the human body and, among these, 9% are distributed in the genitourinary system. The microbiota plays a key role in controlling the homeostasis, therefore dysbiosis can lead to an alteration of the physiological state of health. An alteration of female reproductive microbial communities may affect fertility due to an alteration of the vaginal and endometrial ecosystem. A perturbation of the vaginal, cervical or endometrial flora may also have an impact on the outcome of assisted reproductive technology procedures, particularly in vitro fertilization and embryo transfer. This review examines the role of microbiota in human reproduction and its contribution to infertility. In addition we investigate the role of endometrial bacteria in recurrent implantation failure.

The X-linked Cyclin-Dependent Kinase-Like 5 (CDKL5) gene encodes a serine-threonine kinase highly expressed in the developing brain. Loss of function of CDKL5 is pointed out to underlie the CDKL5 Deficiency Disorder (CDD), an X-linked dominant disease characterized by early-onset epileptic encephalopathy and developmental delay, usually affecting females more than males. To the best to our knowledge, only 45 males with CDD have been reported so far. Type and position of CDKL5 variants with different impact on the protein are reported to influence the clinical presentation. X-chromosome inactivation occurring in females and post-zygotic mosaicism in males are also believed to contribute to this variability. Based on these issues, genotype-phenotype correlations are still challenging. Here, we describe clinical features of five additional affected males with unreported CDKL5 variants, expanding the molecular spectrum of the disorder. We also reviewed the clinical profile of the previously reported 45 males with molecularly confirmed CDD. Severe developmental delay, cortical visual impairment, and early-onset refractory epilepsy characterize the CDD picture in males. By assessing the molecular spectrum, we confirm that germ-line truncating CDKL5 variants, equally distributed across the coding sequence, are the most recurrent mutations in CDD, and cause the worsen phenotype. While recurrence and relevance of missense substitutions within C-terminal remain still debated, disease-causing missense changes affecting the N-terminal catalytic domain correlate to a severe clinical phenotype. Finally, our data provide evidence that post-zygotic CDKL5 mosaicism may result in milder phenotypes and, at least in a subset of subjects, in variable response to antiepileptic treatments.

Endometriosis is a chronic disease frequently associated with female infertility. The choice of treatment in case of endometriosis is one of the most discussed topics in Reproductive Medicine. The approach to the patient with endometriosis and infertility should be tailored based on different parameters. The localization of the disease, the severity of symptoms and the age of the patient are just some of them. Management options include surgery, in-vitro fertilization (IVF), or a combination of both. Data, mostly uncontrolled, would favor surgery at any stage of endometriosis, increasing the chances of natural conception compared to expectant management. Laparoscopic excision of the ovarian endometrioma should be the treatment of choice when there is associated pain. Surgery should be performed following appropriate techniques to reduce the possible damage to the ovarian reserve. Pregnancy rates around 50% have been consistently reported after surgery, which compare favorably with those obtained with IVF. IVF, on the other hand, may be preferred in case of associated male or tubal factor, in case of a reduced ovarian reserve, or if previous surgery has failed, particularly if there is no associated pain, and when the ultrasonographic features of the ovarian cyst are reassuring. Sometimes IVF may be preceded by surgery, when a difficult access to follicles at pick-up, due to the size and location of the ovarian cyst, or to severe adhesions, is anticipated. Due to the lack of solid evidence in the scenario of endometriosis-associated infertility, robust data from randomized clinical trials (RCTs) are strongly needed.

OBJECTIVE: Infertility is an increasingly frequent health condition, which may depend on female or male factors. Oxidative stress (OS), resulting from a disrupted balance between reactive oxygen species (ROS) and protective antioxidants, affects the reproductive lifespan of men and women. In this review, we examine if alpha lipoic acid (ALA), among the oral supplements currently in use, has an evidence-based beneficial role in the context of female and male infertility. METHODS: We performed a search from English literature using PubMed database with the following keywords: 'female infertility', 'male infertility', 'semen', 'sperm', 'sub-fertile man', 'alpha-lipoic acid', ' alpha lipoic acid', 'lipoid acid', 'endometriosis', 'chronic pelvic pain', 'follicular fluid' and 'oocytes'. We included clinical trials, multicentric studies and reviews. The total number of references found after automatically and manually excluding duplicates was 180. After primary and secondary screening, 28 articles were selected. RESULTS: The available literature demonstrates the positive effects of ALA in multiple processes from oocyte maturation (0.87 ± 0.9% of oocyte in MII vs 0.81 ± 3.9%; p < .05) to fertilization, embryo development (57.7% vs 75.7% grade 1 embryo; p < .05) and reproductive outcomes. Its regular administration both in sub-fertile women and men shows to reduce pelvic pain in endometriosis (p < .05), regularize menstrual flow and metabolic disorders (p < .01) and improve sperm quality (p < .001). CONCLUSIONS: ALA represents a promising new molecule in the field of couple infertility. More clinical studies are needed in order to enhance its use in clinical practice.

BACKGROUND: Huntington's disease (HD) is an autosomal-dominant neurodegenerative disorder inducing motor, psychiatric changes and cognitive decline, characterized pathologically by striatal atrophy. Pathological changes in the extra-striatal structures, such as the substantia nigra (SN), and abnormalities in pre-synaptic striatal dopamine neurotransmission are also known to occur. Neuromelanin (NM)-sensitive magnetic resonance imaging (NM-MRI) is an innovative technique that was recently developed allowing the in vivo study of pathological changes in the dopaminergic neurons of the SN. OBJECTIVE: To investigate the SN MR signal in HD patients. METHODS: We performed a cross-sectional study using a specific T1-weighted MR sequence to visualize NM. The areas and signal intensity contrast ratios of the T1 hyperintense SN regions were obtained using a semi-automatic segmentation method. RESULTS: A total of 8 HD patients and 12 healthy subjects were evaluated. The SN area was markedly reduced in the HD group compared with the control group (p = 0.02), even after normalization of the SN area with the midbrain area and age correction (p = 0.01). There was a significant reduction in the intensity contrast ratio of the hyperintense SN areas to crus cerebri in HD patients comparing with controls (p = 0.04) after correction for age. CONCLUSIONS: NM-sensitive MR techniques were used for the first time to study the SN in HD patients, showing loss of NM in this region, supporting the implication of dopaminergic neuronal changes in disease pathology. Future research needs to be conducted to evaluate the potential of SN area and intensity contrast as biomarkers for HD.
