Sperm bauplan and function and underlying processes of sperm formation and selection
The spermatozoon is a highly differentiated and polarized cell, with two main structures: the
head, containing a haploid nucleus and the acrosomal exocytotic granule, and the flagellum …

Comparative analysis of mammalian sperm ultrastructure reveals relationships between sperm morphology, mitochondrial functions and motility
NH Gu, WL Zhao, GS Wang, F Sun - Reproductive Biology and …, 2019 - Springer
Background Sperm morphology mainly refers to the shape of the head, the length of the
flagellar segments, including the midpiece, principal piece and end piece, and the size of …

Methodological considerations for examining the relationship between sperm morphology and motility
Sperm cells of all taxa share a common goal to reach and fertilize an ovum, yet sperm are
one of the most diverse cell types in nature. While the structural diversity of these cells is well …

Fertilization mode differentially impacts the evolution of vertebrate sperm components
Environmental change frequently drives morphological diversification, including at the
cellular level. Transitions in the environment where fertilization occurs (ie, fertilization mode) …

Biophysical determinants and constraints on sperm swimming velocity
Over the last 50 years, sperm competition has become increasingly recognised as a potent
evolutionary force sha** male ejaculate traits. One such trait is sperm swimming speed …

Physical and physiological impacts of ocean warming alter phenotypic selection on sperm morphology
Global warming may threaten fertility, which is a key component of individual fitness and vital
for population persistence. For males, fertility relies on the ability of sperm to collide and fuse …

Sperm swimming speed and morphology differ slightly among the three genetic morphs of ruff sandpiper (Calidris pugnax), but show no clear polymorphism
The ruff sandpiper (Calidris pugnax) is a lekking shorebird with three male morphs that differ
remarkably in behavior, ornaments, size, and endocrinology. The morphs are determined by …

The impact of diet quality on the velocity, morphology and normality of sperm in the zebra finch Taeniopygia guttata
Sperm traits can influence fertilisation success, but there is still much we do not understand
about sperm condition dependence, that is, how much sperm traits depend on the male's …
