This review assesses the current literature on COVID-19's effects on male sexual and reproductive health, highlighting significant research gaps and providing guidance for patient counseling.

High testosterone to epitestosterone ratio in hair could predict male-pattern baldness.

In this study, the authors concluded that COVID-19 may not cause direct long-term harm to testicular function, but temporary indirect effects could occur, suggesting a possible delay in pursuing parenthood post-recovery.

This review discusses the genetic research developments in androgenetic alopecia, reporting no new clinical results, and highlights the potential for discovering novel therapeutic targets.

This study found that finasteride at 1 mg/day was the most effective dose for treating male pattern hair loss, with similar efficacy to 5 mg/day and better results than lower doses.

In this study, researchers observed that testicular 17β-hydroxysteroid dehydrogenase deficiency in an inbred Arab population in Israel leads to genital ambiguity at birth and progressive virilization after puberty.

This article discusses various hair and nail abnormalities linked to paraneoplastic conditions and cancer treatments, emphasizing their potential role in diagnosing and managing internal malignancies and reports no new clinical findings.

The researchers reported that a new nanoformulation of paclitaxel-loaded nanoparticles showed superior antitumor effects against malignant melanoma in vitro and in vivo compared to the commercial formulation Taxol^®.

In this study, higher scores of HOMA-IR and FIRI suggested that male patients with early-onset androgenetic alopecia may have insulin resistance, although no significant differences in metabolic syndrome were found compared to controls.

This study suggests that the AGA risk haplotype in Europeans was driven to high frequency by positive selection, likely associated with a variant in the EDA2R gene.

This study found that 58% of men aged 30-50 had androgenic alopecia, with disease severity increasing with age and many being candidates for medical treatment or hair transplantation.

This study observed that 2% minoxidil solution was at least as effective as 3% for increasing hair growth and stabilizing bald areas in men with male pattern baldness.

This paper discusses mechanisms by which various chemicals disrupt male sexual differentiation, concluding that mixture risk assessments should include a broader set of compounds beyond phthalates to address cumulative reproductive health risks.

In this study, the researchers reported that chloramphenicol-loaded liposomes, particularly those incorporating deoxycholic acid, enhanced follicular uptake and showed strong antibacterial activity against methicillin-resistant Staphylococcus aureus, offering potential for treating MRSA-infected skin conditions with good skin biocompatibility and minimal toxicity.

This review addresses the limited efficacy of current treatments for male pattern baldness and explains that emerging genetic insights could lead to more effective future therapies.

This study found that Malt1, particularly its protease activity, plays a crucial role in maintaining Treg cell function and homeostasis, with its inactivation leading to autoimmune diseases and altered immune responses in mice.

This study in identical twin males with androgenetic alopecia found that dutasteride significantly improved hair growth compared to placebo over one year.

In this study, researchers reported that about one-third of men with premature alopecia displayed hormonal shifts and higher insulin resistance, resembling the prevalence pattern of PCOS in women.

This study suggests that the AR/EDA2R locus may contribute to early-onset female pattern hair loss, but no association was found with the 20p11 locus.

This study found that higher BMI was significantly associated with more severe hair loss in men with male-pattern and early-onset androgenetic alopecia.

This study found that early-onset androgenic alopecia is associated with a higher risk of developing prostate cancer, although it was not linked to earlier diagnosis or more aggressive tumors.

In this case report, a male patient's semen parameters improved after discontinuing a 1-mg dose of finasteride, suggesting that stopping the medication may benefit infertile men with previous sperm production issues.

This review summarizes existing research on the use of finasteride for treating androgenetic alopecia in men, reporting its effectiveness at 1 mg/day and a strong safety profile, but presents no new findings.

Minoxidil can help grow hair and make hair follicles bigger, but it can also cause side effects.

This study found that administering the gut bacterium Thauera sp. strain GDN1 to mice significantly reduced their serum androgen levels, indicating gut bacteria may influence androgen metabolism.

This study found that a genetic model using SNPs can predict early-onset male-pattern baldness with moderate accuracy, which may assist in decisions about interventions.

This study found that environmental factors such as smoking, alcohol consumption, exercise, and testosterone levels may significantly influence various forms of hair loss in male identical twins.

This article updates Japanese guidelines for diagnosing and treating male and female-pattern hair loss, recommending specific drugs and therapies while advising against certain treatments for female-pattern hair loss.

This study found that 5-alpha-reductase inhibitors were associated with a reduced frequency of COVID-19 symptoms in males with androgenetic alopecia.

Injecting platelet-rich plasma (PRP) can increase hair growth rate and density in male pattern baldness.
