Objective: To investigate whether idiopathic nonobstructive azoospermia (iNOA) has its own transcriptomic signature.
Design: Testicular tissue biopsies were retrieved, processed, and prepared for ribonucleic acid (RNA) extraction from 26 consented patients diagnosed with iNOA. Samples were grouped into four pools based on the presence of testicular spermatozoa: two replicate pools for "No presence" (Null-spz-1 and Null-spz-2 pools), one for "High presence" (High-spz pool), and one for "Rare presence" (Rare-spz pool).
Azoospermia and severe oligozoospermia represent the most extreme forms of male infertility. Despite their prevalence, the genetic foundations of these conditions are not well understood, with only a limited number of genetic factors identified so far. This study aimed to identify single-nucleotide polymorphisms (SNPs) linked to both azoospermia and severe oligozoospermia.

Apremilast, a small molecule primarily metabolized by cytochrome CYP3A4, modulates the immune system by specifically inhibiting phosphodiesterase type 4 (PDE4) isoforms and is currently used for the treatment of Ps and psoriatic arthritis (PsA). Clinical trials and real-world data showed variable efficacy in response among Ps patients underlying the need for personalized therapy.

Body-fat composition and distribution are closely associated with obesity, but the human body's composition is a sexually dimorphic trait, as differences between the two sexes are evident even from fetal life. The effect of sex hormones contributes to this phenomenon.

Pre-mRNA splicing perturbations have been linked with neurodevelopmental diseases. variants have been, recently, causally linked with severe neuropathological and growth retardation phenotypes.
