Scientifically speaking "Romantic Chemistry / Sexual Chemistry" is determined by the Major Histocompatibility Complex (MHC) a group of proteins that pepper the surface of your cells that help your immune system to recognize and fight pathogens. The MHC genes are also known to influence mate-choice in many vertebrates, and variations in the DNA code of MHC genes are known to influence human partner choice. The sweaty t-shirt experiments demonstrated that MHC influences both body scent and body scent preferences in humans (Wedekind et al., 1995 ,...etc...Kromer et al., 2016), where people with very different MHC genes tend to find each others scent pleasant, while people with similar MHC genes will find each other's scent to smell repulsive. Opposites do attract!

一项针对亚裔美国人的研究发现，基于 MHC 的吸引力 AKA "浪漫化学" 一样重要 "性格类型"在预测第二次约会时 (Wu et al., 2018). MHC genes also play a role in partner choice of other vertebrates, an facinating study in obligate pair-living lemurs showed that couples with mismatched MHC genes tend to make an extra-pair partner selection the cause of lemur affairs (Schwensow et al., 2008). MHC compatibility is so important that scientists have proposed humans invented kissing as a way to test for chemistry, and this biological phenomenon can even help explain the strength of the female orgasm (Sherlock et al., 2016).
