Young women receive estrogen, progesterone and some testosterone and transform into women. There is a particular subgroup of young women who have a metabolic disorder called Stein-Leventhal disorder, something else known as polycystic ovary disorder (PCOS). In addition to having polycystic ovaries, these young women have excessive amounts of testosterone and regular DHEA. They create unpredictable and difficult times, but the most important thing in this discussion is that they are masculinized. They have become very bony, huge, generally overweight, have a noticeable apex, and are quite shaggy. There is strong evidence pointing to lesbianism in these women. It's an interesting conclusion to reach in the case of a young woman besieged by regularly virile levels of testosterone and DHEA from adolescence onwards that there may be a very real impact on the development of sexual personality and desire. Additionally, there is a disorder called testicular feminization in which hereditarily male (XY) children are born with clearly female genitalia and create physically and emotionally in terms of sexual attraction towards the female. They have retained gonads and their bodies are hard on testosterone. So, the body considers testosterone as estrogen and they become feminine. The human body's testosterone is broken down into estrogen (estradiol), which men take regularly, just as women take testosterone regularly. Genes also play an important role in homosexuality. Most would agree that the introduction of a gay male person is not a basic Mendelian characteristic. There would be strong specific pressures against such quality. Hamer's recognizable evidence of a link of a gene near Xq28 to homosexuality in some families selected for X-linked transmission of that trait may be rife with type 1 known as false positive error. This is usually critical to consider, given the irreproducibility of numerous linkages for complex behavioral traits.” In addition to this, chromosome 13 is dynamic in a portion of the brain called the diencephalon which is located in the hypothalamus to varying degrees between gay and heterosexual men. As for chromosome 14 which is basically dynamic within the thyroid. A receptor protein called TSHR that senses and binds to a hormone that has activated the thyroid. The fact that the TSHR appears to be included in sexual introduction confirms that the work of the thyroid appears to be linked to sexuality. Please note: this is just an example.

DNA expression is influenced by any number of external components in the environment. And in the case of homosexuality, analysts argue, the environment is the uterus itself. There is evidence that genetic varieties influence sexual orientation, but no evidence that a gene or set of genes makes an individual homosexual.
