As is well known, sex hormones have the function of promoting the development and maturation of the body's sexual organs. Female animals mainly secrete estrogen and progesterone, while males secrete androgens. So the problem is, sex hormones cannot circulate in the blood after secretion, and why is that? Let's explore the reasons behind it together.
It is understood that sex hormones mainly bind to sex hormone binding proteins in the blood after secretion before they can circulate in the blood, rather than just circulating in the form of sex hormones. In addition, the non outcome state, also known as the free state, plays a physiological role. This is only a superficial situation, some sex hormones can also enter deeper bodily fluids.
It can be seen that sex hormones cannot shuttle through the bloodstream alone and must be combined with specific carriers in order to circulate in the bloodstream. From the side, it can be seen that the molecular volume of sex hormones is likely larger than the shuttle holes that enter the bloodstream, and sex hormone binding proteins are like tickets.
Therefore, the above explanation is about why sex hormones cannot enter the bloodstream. I hope to help friends increase their knowledge in this area, improve their insights, and enrich their knowledge. If you want to learn something deeper, you can explore more.
