Male Mice Heterozygous for Protamine 1 and Protamine 2 Are Infertile, Displaying Sperm Damage and Retention of Protamine 2 Precursors, Transition Proteins, and Histones

Andrology, EarlyView.
ABSTRACT Background During spermiogenesis, protamines (PRMs) replace histones to hypercondense and protect sperm DNA. Rodents and primates express two PRMs (PRM1 and PRM2). Alterations of species‐specific PRM ratios are associated with sub‐ or infertility in mice and humans.

Father–Son Comparison of Reproductive Traits

Andrology, EarlyView.
ABSTRACT Background Little is known about the relative contribution of genetic and environmental factors on male reproductive function. Objectives We studied in a cross‐sectional setting, whether testicular function and genital size correlate in father–son pairs.

Male Sexual and Reproductive Health in Diabetes and Obesity Pharmacotherapy: A Source‐Triangulated Counseling Map

Andrology, EarlyView.
ABSTRACT Background Drugs used for diabetes and obesity increasingly shape male sexual and reproductive counseling, but clinical studies, trial registrations, regulatory labels, and patents answer different questions. Objectives The objective is to map these sources and define what each can support when counseling men receiving metabolic drugs ...

Deep‐Learning‐Based Profiling of Mouse Sperm Head and Neck Morphology Reveals Coordinated Structural Variation

Andrology, EarlyView.
ABSTRACT Background Mammalian sperm head morphology varies across species and dictates fertilization capability. Rodent sperm have asymmetric, hook‐shaped heads, complicating analysis. Despite widespread biomedical use, current tools poorly characterize these complex variations.

The Impact of Common Medications on Male Fertility: An Updated Systematic Review

Andrology, EarlyView.
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...
