New treatments for male hypogonadism are effective and should be personalized.

This abstract explains that androgenetic alopecia, a common hair loss disorder influenced by genetics and hormones like dihydrotestosterone, has FDA-approved treatments including minoxidil, finasteride, and photolaser therapy, but its genetic basis and susceptibility to environmental factors remain complex.

Acute leukemias with the Philadelphia chromosome may be biphenotypic, and identifying this is important for proper treatment.

This article reviews the clinical and biochemical features of genetic mutations affecting dihydrotestosterone production and their potential role in male pseudo-hermaphroditism, but presents no new clinical results.

This study reports that incomplete information in a reverse supply chain can lead to efficiency losses, but a two-part tariff contract for the remanufacturer may improve performance by eliciting private information from collectors.

In this study, finasteride was found to significantly reduce DHT levels and affect spermatogenic markers in rats, while DA-9401 co-treatment indicated potential ameliorative effects.

The study found that finasteride increased endoplasmic reticulum stress and reduced fertility in rats, effects that were alleviated by the administration of DA-9401.
