The function of sperm is to safely transport the haploid paternal genome to the egg
containing the maternal genome. The subsequent fertilization leads to transmission of a new …

Concentration, motility and morphology are parameters commonly used to determine the
fertilization potential of an ejaculate. These parameters give a general view on the quality of …

De novo mutations (DNMs) are important in autism spectrum disorder (ASD), but so far
analyses have mainly been on the~ 1.5% of the genome encoding genes. Here, we …

Protamines are the major nuclear sperm proteins. The human sperm nucleus contains two
types of protamine: protamine 1 (P1) encoded by a single-copy gene and the family of …

Purpose Advancing maternal and paternal age leads to a decrease in fertility, and hence,
many infertile couples opt for assisted reproductive technologies [ART] to achieve biological …

Spermatogenesis, a study of germ cell development, is a long, orderly, and well‐defined
process occurring in seminiferous tubules of the testis. It is a temporal event whereby …

Small interfering RNAs and microRNAs are generated from double-stranded RNA
precursors by the Dicer endonucleases, and function with Argonaute-family proteins to …

BACKGROUND: This study examined potential associations between exposure to episodes
of air pollution and alterations in semen quality. The air pollution, resulting from combustion …

Mosaicism—the existence of genetically distinct populations of cells in a particular organism—
is an important cause of genetic disease. Mosaicism can appear as de novo DNA mutations …

The fundamental underlying paradigm of sexual reproduction is the production of male and
female gametes of sufficient genetic difference and quality that, following syngamy, they …
