Erectile dysfunction (ED) seems to be a widespread sexual issue in men affected by chronic obstructive pulmonary disease (COPD). Multiple causes appear to be involved such as hormonal imbalance, smoking habit, chronic inflammation, endothelial dysfunction, chronic hypoxia, psychiatric disorders (depression and anxiety), and medications. ED can have a significant impact on COPD men and consequently on their quality of life, which is usually already compromised. Given this situation, however, pneumologists usually do not properly care for the sexuality of COPD patients especially because men can be reluctant to talk about their intimate issues. The aim of this narrative review is to briefly summarize the evidence emerging from literature and to provide a wide point of view about sexual dysfunction in COPD men.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may affect testicles. Lower testosterone levels have been associated with worse clinical outcomes and higher mortality. Our objective was to evaluate the hypothalamic–pituitary–gonadal axis of men admitted with SARS-CoV-2 pneumonia and its link with the pneumonia-treatment intensification. Short-term changes in hormonal parameters were also assessed. Methods: Men admitted with SARS-CoV-2 pneumonia were recruited in two different hospitals in Piedmont, Italy. In all patients, the assessment of total testosterone (TT), calculated free testosterone (cFT), gonadotropins, inhibin B (InhB), and other biochemical evaluations were performed at admission (T0) and before discharge (T1). Through a review of medical records, clinical history was recorded, including data on pneumonia severity. Results: Thirty-five men (median age 64 [58–74] years) were recruited. Lower TT and cFT levels at T0 were associated with CPAP therapy (p = 0.045 and 0.028, respectively), even after adjusting for age and PaO2/FIO2 ratio in a multivariable analysis. In those discharged alive, lower TT and cFT levels were associated with longer hospital stay (p < 0.01). TT, cFT, and InhB were below the normal range at T0 and significantly increased at T1 (TT 1.98 [1.30–2.72] vs. 2.53 [1.28–3.37] ng/mL, p = 0.038; cFT (0.0441 [0.0256–0.0742] vs. 0.0702 [0.0314–0.0778] ng/mL, p = 0.046; InhB 60.75 [25.35–88.02] vs. 77.05 [51.15–134.50], p < 0.01). Conclusions: Both TT and cFT levels are associated with adverse clinical outcomes in men admitted with SARS-CoV-2 pneumonia. As TT, cFT and InhB levels increase before discharge, short-term functional recovery of steroidogenesis and an indirect improvement of spermatozoa functional status could be hypothesized.

Purpose: Testosterone therapy represents the cornerstone of gender affirming hormone therapy (GAHT) among t-AFAB (transgender Assigned Female At Birth) people. Minoxidil is a vasodilator drug approved for topical use for the treatment of androgenetic alopecia. The aim of the present study was to evaluate the efficacy of topical minoxidil in enhancing beard growth in a group of t-AFAB people on GAHT. Methods: Sixteen t-AFAB individuals with an incomplete beard development, on GAHT for at least 6 months, were enrolled. Topical minoxidil was applied to the interested facial areas. Before starting (T0), after 3 (T3) and 6 (T6) months, we evaluated facial hair growth using the Ferriman-Gallwey modified score (FGm). Results: Subjects were 26 (2.7) years old and on GAHT for 18.5 [15–54] months; using a paired match evaluation, a statistically significant facial hair growth was observed over time, in particular at T6 (median upper lip FGm 3.5 [3–4] vs 2 [1–2] at T0 and chin FGm 4 [3.25–4] vs 1 [1–2] at T0; p ≤ 0.002). Comparing the minoxidil group with a control group (n = 16) matched for age and BMI who developed a full-grown beard only with GAHT, a logistic multivariable analysis identified hirsutism before GAHT was independently positively associated with the development of a full beard [OR 15.22 (95% CI 1.46–158.82); p = 0.023]. Conclusions: This is the first study demonstrating the efficacy of topical minoxidil in enhancing facial hair growth among t-AFAB people on GAHT. Further studies will be necessary to assess whether the obtained improvements will persist after discontinuing the medication.

Transgender and gender diverse individuals experience a gender identity that differs from the sex assigned at birth. Some transgender men may request testosterone to induce virilization; however, its impact on bone health remains to be fully elucidated. The objective of this systematic review and meta-analysis was to evaluate the modifications in bone metabolism over a short-term period among transgender men initiating testosterone therapy. A systematic search was conducted in PubMed, Scopus, Web of Science, and Cochrane Library. The articles of interest had to report longitudinal evaluation conducted among transgender men, before starting testosterone and after 12 and 24 months of therapy. The analyzed parameters were BMD, calcium, phosphate, 25OHD, PTH, P1NP, BAP, osteocalcin and CTx. Mean differences with 95% coefficient intervals were combined using random effects models. Funnel plot, Egger’s test, and trim-and-fill analysis were used to assess publication bias. Fourteen studies met the inclusion criteria, including 1484 subjects. In absence of heterogeneity, BMD did not significantly change at lumbar spine, hip, femoral neck, and whole-body evaluations. Calcium, phosphate, 25OHD and PTH remained stable over time. Regarding bone turnover markers, only P1NP showed a statistically significant increase after 12 months of T therapy, in absence of heterogeneity (SMD 0.61 mcg/l; 95% CI: 0.40–0.83; p < 0.0001; I2 = 0%, Pforheterogeneity = 0.48). Testosterone therapy among transgender men seems not to disrupt bone health after 12 and 24 months. A statistically significant elevation in P1NP levels after 12 months of therapy may indicate a positive anabolic effect of testosterone in the short-term.
