Sperm cells A sperm cell is the male reproductive cell that carries the male portion of chromosomes and deoxyribonucleic acid (DNA) information to be fused with the female egg or ovum. The sperm cell carries various amount of heredity information inside the cell nucleus. There are various ways ...
Vagina, canal in female mammals that receives the male reproductive cells, or sperm, and is part of the birth canal during the birth process. In humans, it also functions as an excretory canal for the products of menstruation. Learn more about the functi

The 'S' shaped duplex gland, the shortest among the male reproductive glands, ultrastructurally exhibits only a single cell type, characterized by the presence of multishaped rough endoplasmic reticulum, polymorphic Golgi bodies and vesicles. The frequent mode of secretion appears apocrine, with occasi...

to produce sperm (the male reproductive cell), and to produce testosterone (the male sex hormone). The epididymides and the vasa deferentia are attached to the testicles and are important in transporting sperm cells after they develop in the testes. ...
The assessment of sexual function in women with male partners who have erectile dysfunction To investigate the role of fexofenadine, a mast cell blocker, on semen quality in the treatment of infertile men.

Sperm were negative. The only exception was that there may be a subset of elongate spermatid (steps 11-13) in rat that contained high levels of topo I and II, perhaps to relieve torsional stress during the nucleohistone/protamine transition. The enzymes were mostly nuclear, and topo II$\\...
