Capacitation is the physiological process that sperm must undergo to gain the ability to penetrate and fertilize an egg.
This process occurs after the sperm enters the female reproductive tract
They involve a series of biochemical changes that enhance the sperm's motility, and its ability to bind to the egg.
It is distinct from spermiogenesis (the final stage of sperm development), the acrosome reaction (which occurs later during fertilization), and fertilization itself
Luteinizing Hormone (LH) is a glycoprotein hormone.
It is composed of two subunits, alpha and beta, with attached carbohydrate groups.
LH plays a crucial role in regulating the reproductive system, particularly in triggering ovulation in females and stimulating testosterone production in males.
It is not a steroid, peptide, or lipid, but specifically a glycoprotein.
The class Solenogastres (also known as Solengasters) lacks a shell and possesses sclerites, which are small, hard, plate-like structures embedded in the skin.
These organisms are part of the phylum Mollusca, specifically in the class Solenogastres.
