Background/Objectives: Fertility preservation (FP) has become an integral component of multidisciplinary care for patients at risk of treatment- or disease-related infertility. Although several established and emerging fertility preservation strategies are currently available, important challenges remain regarding patient selection, timing of intervention, long-term reproductive outcomes, and the translation of experimental approaches into routine clinical practice. This review critically appraises the current evidence on female and male fertility preservation, highlighting established techniques, emerging technologies, unresolved clinical challenges, and future research priorities. Oocyte vitrification remains the preferred strategy for postpubertal women when ovarian stimulation is feasible, whereas ovarian tissue cryopreservation has become an established option for selected patients requiring urgent treatment or for prepubertal girls. In men, sperm cryopreservation remains the standard of care, while fertility preservation in prepubertal boys is still investigational. Despite excellent laboratory outcomes, the real-world utilization of cryopreserved reproductive material remains unexpectedly low, highlighting persistent barriers in patient referral, counselling, and long-term follow-up. Methods: A structured narrative review was conducted using PubMed/MEDLINE and Embase to identify international guidelines, systematic reviews, meta-analyses, multicentre cohorts, registry-based studies, and original clinical investigations published between January 2015 and June 2025. Evidence was synthesized according to sex, age, fertility preservation indication, and clinical applicability. Interventions reviewed include oocyte and embryo cryopreservation, ovarian tissue cryopreservation (OTC), GnRH agonist co-treatment, ovarian transposition, in vitro maturation (IVM), sperm banking, surgical sperm retrieval (SSR), testicular tissue cryopreservation (TTC), and spermatogonial stem-cell (SSC) approaches. Results: Oocyte vitrification remains the preferred strategy for postpubertal women when ovarian stimulation is feasible, whereas ovarian tissue cryopreservation has become an established option for selected patients requiring urgent treatment or for prepubertal girls. In men, sperm cryopreservation prior to therapy is standard; SSR provides sperm for selected azoospermic cases. Paediatric FP strategies are asymmetric: OTC is clinically established, while TTC remains investigational. Random-start COS and aromatase inhibitor or tamoxifen protocols minimise treatment delay and hormonal exposure, and GnRHa co-treatment can serve as an adjunctive ovarian-protective measure. Despite high laboratory success, utilisation of banked gametes and tissue is modest, underscoring the need for structured referral pathways, patient counselling, and longitudinal follow-up. Conclusions: FP should be systematically integrated into both oncological and non-oncologic care pathways, with timely referral, age- and sex-specific counselling on live-birth probabilities, and long-term follow-up. Future priorities include harmonization of clinical protocols, standardized outcome reporting, registry-based long-term follow-up, and validation of emerging technologies to improve both reproductive outcomes and equitable access to fertility preservation.

Background/Objectives: Fertility preservation (FP) spans oncological and non‑oncological indications, including gonadotoxic therapies, benign haematological/metabolic disorders, conditions at risk of premature ovarian insufficiency, severe andrological disease, and elective plans to defer childbearing. We provide a sex‑integrated overview of established and emerging FP strategies and their real‑world effectiveness [1–10]. Methods: Narrative synthesis of guidelines and high‑quality studies (to 2025), prioritising ASCO/ESHRE guidance, systematic reviews, and multicentre/registry data covering oocyte/embryo cryopreservation, ovarian tissue cryopreservation (OTC), GnRH agonists, ovarian transposition, in vitro maturation (IVM), sperm banking, surgical sperm retrieval (SSR), testicular tissue cryopreservation (TTC), and spermatogonial stem‑cell (SSC) approaches [1–10]. Results: For women, oocyte vitrification is the first‑line option when time allows; OTC is established when stimulation is infeasible or in prepubertal girls, with endocrine recovery common and increasing pregnancy/live‑birth reports. For men, sperm cryopreservation before therapy is standard; SSR supports selected cases. Paediatric TTC is feasible but remains experimental, whereas paediatric OTC is clinically implemented. Random‑start COS and letrozole/tamoxifen protocols minimise treatment delay and hormonal exposure; GnRHa co‑treatment preserves ovarian function as an adjunct. Utilisation of banked gametes/tissue remains modest, underscoring the need for pathway optimisation [1–10]. Conclusions: FP should be embedded across oncology and non‑oncology pathways with timely referral, clear counselling on probabilities of live birth, and robust follow‑up. Standardisation, registry‑based evidence and long‑term offspring safety data are priorities to bridge the gap between laboratory potential and clinical effectiveness [1–10].

Children with epilepsy and identified as responders to antiseizure medications (ASMs) were found to present markedly higher ghrelin plasma levels when compared to drug-resistant patients. However, it was undetermined if this phenotype could be influenced by the ASMs. Here, we prospectively investigated total ghrelin and des-acyl ghrelin (DAG) plasma levels by enzyme-linked immunosorbent assay before and after ASM administration. Inclusion criteria were: (i) subject with a suspicion of epilepsy; (ii) age ranging from 0 to 16 years; and (iii) informed consent signed by parents or caregivers. Exclusion criteria were acute or chronic metabolic disorders with occasional convulsions but without epilepsy. Fifty patients were followed over a period of one year in Italian neuropediatric centers. Apart from a few exceptions, the majority of children were responsive to ASMs. No differences were found in total ghrelin and DAG levels before and after the treatment, but total ghrelin levels were significantly lower in children with generalized epilepsy compared to those with combined focal and generalized epilepsy. Moreover, the ghrelin-to-DAG ratio was also markedly lower in generalized epilepsies compared to all the other types of epilepsy. Finally, ghrelin was unchanged by ASMs, including the first (e.g., carbamazepine), second (levetiracetam), and third (lacosamide) generation of anticonvulsants.

Purpose To cope physical and/or psychological threats, the human body activates multiple processes, mediated by a close interconnection among brain, endocrine and inflammatory systems. The aim of the study was to assess the hypothalamic–pituitary–adrenal (HPA) and hypothalamic–pituitary–thyroid (HPT) axes involvement after an acute stressful event (Emilia Romagna earthquake swarm) with a big data approach. Methods A retrospective, observational trial was performed, collecting all biochemical examinations regarding HPA and HPT axes performed in the same laboratory the year before and the year after the earthquake swarm (20–29 May 2012). Results Comparing 2576 pre-earthquake to 3021 post-earthquake measurements, a cortisol serum level increase was observed (p < 0.001). Similar increase was evident for urinary free cortisol (p = 0.016), but not for adrenocorticotropic hormone (p = 0.222). The biochemical hypercortisolism incidence increased from 7.6 to 10.3% after earthquakes (p = 0.001). Comparing 68,456 pre-earthquake to 116,521 post-earthquake measurements, a reduction in thyroid-stimulating hormone (TSH) levels was evident (p = 0.018), together with an increase in free triiodothyronine and free thyroxine levels (p < 0.001 and p < 0.001). Moreover, a significant increase in altered TSH after earthquakes was registered considering the epicenter-nearest measurements (p < 0.001). No clinically relevant alterations were observed considering thyroid-specific autoantibodies. Conclusion A long-term HPA axis activation in the inhabitants of the earthquake-affected areas was highlighted for the first time. Moreover, an increased incidence of biochemical hypercortisolism emerged after earthquakes. We confirmed a recruitment of HPT axis after stressful events, together with increased incidence of altered TSH in the. Our big data study allowed to increase knowledge about the connection between external stressors and endocrine regulation.

The present study is the second step (concerning normal diet restoration) of the our previous study (concerning the calcium-free diet) to determine whether normal diet restoration, with/without concomitant PTH (1-34) administration, can influence amounts and deposition sites of the total bone mass. Histomorphometric evaluations and immunohistochemical analysis for Sclerostin expression were conducted on the vertebral bodies and femurs in the rat model. The final goals are (i) to define timing and manners of bone mass changes when calcium is restored to the diet, (ii) to analyze the different involvement of the two bony architectures having different metabolism (i.e., trabecular versus cortical bone), and (iii) to verify the eventual role of PTH (1-34) administration. Results evidenced the greater involvement of the trabecular bone with respect to the cortical bone, in response to different levels of calcium content in the diet, and the effect of PTH, mostly in the recovery of trabecular bony architecture. The main findings emerged from the present study are (i) the importance of the interplay between mineral homeostasis and skeletal homeostasis in modulating and guiding bone’s response to dietary/metabolic alterations and (ii) the evidence that the more involved bony architecture is the trabecular bone, the most susceptible to the dynamical balance of the two homeostases.

Background. Intense physical exercise influences the secretion of hormones involved in several metabolic processes. In particular, an acute cortisol (C) and growth hormone (GH) increase after an acute physical activity is widely demonstrated in literature. Moreover, the testosterone (T)/C ratio was recently proposed as a performance index in male athletes. On the contrary, little is known about hormonal changes in women under physical activity and only few studies evaluated the hormonal trend in an extended period of time. Aim. To evaluate the hormonal changes during an annual volleyball female regular season. Methodology. A longitudinal, retrospective, observational clinical trial was carried out. 28 female professional volleyball players belonging to the same team were enrolled. For each subject, blood samples were collected after 36 hours of rest in four visits. Visit 1 was performed at the beginning of the training phase, visit 2 and 3 were performed during and Visit 4 were performed at the end of the regular season. GH, insulin-like growth factor (IGF)-1, T and C were assessed by immunoenzimatic assays. Results. Both GH and IGF-1 were above the normal range at visit 1 (5.08 ± 5.22 ng/ml; 265.88 ± 105.85 ng/ml). In particular, five athletes had GH above the normal range (17.8%). No alterations of other hormones were found at Visit 1. C significantly changed during the regular season (p=0.009), with higher levels at Visit 2 (p=0.049), compared to visit 1 and the following visits. Similarly, T significantly changed during the season (p=0.013), even if a clear trend was not demonstrated. The post-hoc test showed two peaks of T at Visit 2 and Visit 4 (p=0.029 and p=0.024, respectively). Accordingly, the T/C ratio significantly changed during visits (p=0.009), decreasing of about 30% in the first phase of the regular season, suggesting an overreaching of subjects enrolled. Conclusion. Here we found that chronic intense physical activity influences hormonal levels in female volleyball players. In particular, C secretion is increased at the beginning of the regular season, whereas T serum levels shows a significant fluctuation during the regular season. Moreover, we suggest that T/C ratio could be useful in the evaluation of the training overload in female athletes.

Background. Steroidogenesis is a complex enzymatic process in which cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) play an important role. Phosphodiesterase-5 inhibitors(PDE5i) increase cGMP, improving NO availability. Objective. to investigate whether long-term, chronic treatment with the PDE5i Vardenafil affects adrenal and testicular steroidogenesis in diabetic men, using liquid chromatography-mass spectrometry (LC-MS/MS). Design. A longitudinal, prospective, investigator-started, randomized, placebo-controlled, double-blind, clinical-trial was carried out. Setting and Participants. 54 male patients affected by T2DM diagnosed within the last 5 years were enrolled. 26 and 28 patients were assigned to the verum and placebo-group, respectively. Interventions. The study consisted of an enrolment phase, a treatment phase (24weeks) (Vardenafil/placebo 10mg twice-daily), and a follow-up phase (24weeks). Outcome measurements: progesterone (P), 17-hydroxyprogesterone (17OHP), androstenedione (A), testosterone (T), dehydroepiandrosterone (DHEA), DHEA sulphate (DHEAS), corticosterone, 11-deoxycortisol and cortisol (C), were evaluated using LC-MS/MS. Results. No differences were seen in sex testicular steroids between study and control group. For the adrenal gland, steroids were considered according to the zona in which they are produced. Considering steroids produced in the zona fasciculata, no significant differences were seen in 11-deoxycortisol and C among visits, both in the study and in the control group. For the zona reticularis, DHEA significantly decreased during treatment only in the study group (p=0.007). At post-hoc test DHEA showed higher levels at visit 2 and 8 than in other visits. The DHEAS/DHEAS ratio significantly increased during treatment only in the verum group. Considering the adrenal zona glomerulosa, corticosterone significantly changed among visits both in the study and in the control group (pConclusions. This is the first double-blind, placebo-controlled clinical-trial in which steroidogenesis is extensively investigated by LC-MS/MS in T2DM men chronically treated with Vardenafil for 6 months, and followed-up for 6 months after therapy-withdrawal. Chronically administered Vardenafil reduces DHEA levels and increases DHEAS/DHEA ratio as possible consequences of modulation of steroidogenic enzymes by tissue changes in cGMP and/or cAMP availability. A possibly stress-related increase in corticosterone is suggested for the first time.
