Leydig cells and Sertoli cells respond to gonadotropins (LH and FSH) secreted by the anterior pituitary. Leydig cells have receptors for LH or... View Article
Leydig cells, present in the interstitial spaces of the testicular lobules outside seminiferous tubules, produce testosterone and other... View Article
The primary spermatocyte is a diploid cell and contains 46 chromosomes. Each primary spermatocyte gives rise to four haploid sperms after... View Article
Spermiogenesis is the process by which spermatids transform into sperm or spermatozoa. Spermatids are more like circular cells, which undergo... View Article
Spermiogenesis is the process of transformation of spermatids to spermatozoa. Spermatids undergo morphological changes and transform into sperms.... View Article
FSH or follicle-stimulating hormone secreted by the anterior pituitary mainly regulates the function of Sertoli cells. It stimulates Sertoli... View Article
LH acts on Leydig cells and stimulates the synthesis and secretion of androgens such as testosterone. LH or luteinising hormone is secreted by... View Article
Each secondary spermatocyte produces two sperms after meiosis II, therefore, 200 secondary spermatocytes will produce 400 sperms. Also Check:... View Article
At puberty, spermatogenesis starts. Spermatogonia start dividing and produce primary spermatocytes, which undergo meiosis to produce spermatids.... View Article
The single primary spermatocyte gives rise to four haploid sperms after meiosis. Meiosis produces four unique daughter cells having half the... View Article
Spermatids and spermatocytes are haploid. The only difference is that secondary spermatocytes contain duplicated chromosomes having two... View Article
Each primary spermatocyte produces four spermatids after meiosis, so 25 primary spermatocytes produce 100 spermatids. Also Check: Why Is A... View Article
Zona pellucida is the glycoprotein layer surrounding the plasma membrane of the ovum. It covers the sticky trophoblasts cell initially and... View Article
One primary spermatocyte leads to the formation of four spermatids. The meiotic division in primary and secondary spermatocytes is equal, unlike... View Article
The enzyme hyaluronidase present in the acrosome of the sperm helps in penetrating the corona radiata layer present around zona pellucida. The... View Article
Corona radiata is the multiple layers of the granulosa cells present outside the zona pellucida layer. These cells are held together by a... View Article
Yes, zona pellucida is an acellular layer surrounding the secondary oocyte. It is made up of a glycoprotein matrix. The zona pellucida layer is... View Article
The nucleus contains the genetic material in an egg. It is haploid. The nuclei of egg and sperm fuse to produce a diploid zygote with 2n... View Article
Sertoli cells are the nutritive cells present inside seminiferous tubules. They provide nourishment to the male germ cells. Leydig cells are... View Article
