However, an even larger difference is seen in how many of the seminiferous tubules in the testes contain mature sperm;
22.
In 1979, Levin described germinal cell aplasia with focal spermatogenesis where a variable percentage of seminiferous tubules contain germ cells.
23.
Furthermore, loss of GPR56 leads to reduced fertility in male mice, resulting from a defect in seminiferous tubule development.
24.
These data suggested that cypermethrin can induce impairments of the structure of seminiferous tubules and spermatogenesis in male rats at high doses.
25.
In males, this process is known as spermatogenesis and takes place only after puberty in the seminiferous tubules of the testes.
26.
Its expression in testis is restricted to interstitial cells surrounding seminiferous tubules, which suggests a role in sperm development and fertilization.
27.
:Testosterone is produced by Leydig cells, which you might call part of the " sauce " for seminiferous tubule spaghetti.
28.
I've found that not ejaculating leads to an extremely painful rupture of the seminiferous tubules, usually during a bowel movement.
29.
This differentiation occurs along the longitudinal axis of sertoli cells, from the basement membrane to the apical lumen of the seminiferous tubules.
30.
Because sperm are initially nonmotile as they leave the seminiferous tubules, large volumes of fluid are secreted to propel them to the epididymis.
