sex
Several hormones in the body bind to plasma proteins, including cortisol, thyroxine, and sex hormones like testosterone and estrogen.
Proteins do not directly control the sex of a developing embryo. The sex of an embryo is determined by the combination of sex chromosomes inherited from the parents. In mammals, the presence of a Y chromosome typically leads to the development of a male, while its absence results in a female.
Male sex is tied directly to the Y sex chromosome. The Y chromosome codes for the proteins and enzymes that cause the changes that makes one phenotypically male. Any fetus without a Y chromosome will be genotypically and phenotypically female, only by lack of those proteins and enzymes mentioned before. Given that one sex chromosome comes from the ovum and one comes from the sperm, which fuse at conception, the genotypic and phenotypic sex of the fetus is determined at the time of conceptual fusion of the spermatozoa and ovum.

HIV has not been proven to exist! No virus has been found. It is sex lifestyle. When you have sex you swap proteins. One or a minimal number of people to have sex with is managable to your immune system. When you have casual sex with lots of people, your immune system becomes overtaxed with all of the varieties of foreign proteins. If those habits are maintained, then the immune system eventually shuts down because it can't handle it anymore. Get the REAL lowdown on HIV/AIDS... See the video at this site. You will be glad you did! http://aidsmyth.addr.com/
Human sex hormones belong to the class of biomolecules known as steroids. They include hormones such as testosterone, estrogen, and progesterone, which are derived from cholesterol and play key roles in reproductive functions and secondary sexual characteristics.

Both autosomes and sex chromosomes are types of chromosomes that carry genetic information and are crucial for inheritance. They both consist of DNA and proteins, and they play a role in determining an organism's traits. Additionally, each individual inherits one set of chromosomes from each parent, regardless of whether they are autosomes or sex chromosomes. However, while autosomes are the same in both sexes, sex chromosomes determine the biological sex of an organism and differ between males and females.
