Some studies have shown that individuals with older brothers have an increased predisposition toward homosexuality, and that this probability rises further depending on the number of older brothers. It may be incorrect to reduce homosexuality solely to biological or social factors. Triggers may include biological factors, and one of these could be having an "older brother."
The percentages revealed by this situation, which is explained only by biological accounts, are quite striking. A study examining the increase in the probability of homosexuality in men based on birth order showed that men with older brothers are more likely to be gay.
MORE THAN 5 THOUSAND PARTICIPANTS, 10 SCIENTIFIC STUDIES
Researchers conducted a cross-analysis of 10 scientific studies by examining data from more than 5,000 participants and showed that men with older brothers are 38% more likely to identify as gay. This phenomenon, called the "fraternal birth order effect," explains the biological basis of sexual orientation, and according to this hypothesis, it has been suggested that as the number of biological older brothers increases, the likelihood of homosexual orientation also increases. This effect has been linked to the mother's immune reaction to proteins produced against male fetuses.
These proteins, which pass into the mother's bloodstream, stimulate the production of antibodies that affect the sexual development of subsequent children. These antibodies accumulate in successive pregnancies. Therefore, children are exposed to more "male-specific substances" during birth, and this situation causes an increase in the probability of those with more older brothers being attracted to the same sex.
Research conducted on women with older brothers also yields similar results. Women with older brothers have a higher probability of feeling an attraction toward someone of the same biological sex. These findings supported the idea that the mother's antibodies and fetal proteins interact to influence the sexual development of women.
In conclusion, the gender and number of siblings may play a role in the development of sexual orientation. However, this situation refutes the claim that sexual orientation is "a trend." What is important is not whether sexual identity is innate or a choice, but the respect that society should show to individuals.
