Developmental and Reproductive Toxicology: A Practical Approach
Changes in sperm nuclear morphology should be considered as an adverse
reproductive effect. d) Sperm and Spermatid Numbers — One frequently reported
semen variable for the human is sperm concentration.47 The quantitation of
sperm ...

Reproductive Endocrinology: A Molecular Approach
The manchette is a transient microtubule-containing structure assembled
caudally to the acroplaxome and encircling the elongating spermatid nucleus.
One of the functions of the manchette is the intramanchette transport of cargos to
the ...

Proteomics of Spermatogenesis
The germ cells are sequentially organized into several layers signifying the
respective mitotic or meiotic processes and spermatid development. The
presence of distinct germ cell associations allowed stages of the spennatogenic
cycle of the ...

Knobil and Neill's Physiology of Reproduction
After elongation of mature spermatids and their ascent toward the lumen of the
seminiferous tubule, the spermatid head disengages from the ectoplasmic
specializations and allows the release of sperm from the apical surface of the
Sertoli ...

Reproduction in Domestic Animals
Development of spermatids has been divided into four phases (Golgi, cap,
acrosomal, and maturation phases), based largely upon the development of the
acrosome in the different spermatid types (Fig. 8). Compared to domestic species
, ...

Textbook Of Medical Physiology
Phase of formation of spermatid. Each secondary spermatocyte divides
mitotically to give rise to two spermatids. Thus, a total of 512 spermatids are
formed from a single spermatogonium. • Early spermatid is a small round cell with
spherical ...
Briefly, the Sa spermatid is the earliest form of spermatid, as it contains a
spherical nucleus and a large Golgi with either no acrosomic vesicle, a
developing acrosomic vesicle, or an acrosomal cap. The Sb1 spermatid has a
spherical nucleus ...
