Quote from a Review Yao Body-centered sex is when you have sex because you like the way it makes your body feel. The default concept was first proposed in the early s when Jost performed the groundbreaking experiments to demonstrate mechanisms of sex differentiation of reproductive tracts Jost, , , This research presented a novel model for the maintenance of female ovary differentiation. Convincing evidence challenges us to reconsider the existing paradigm that describes ovarian development as a default system. In adulthood, FOXL2 actively represses Sox9 expression in gonad cells, maintaining the granulosa phenotype. Sertoli cell differentiation and thus testis formation is under the control of the regulatory gene Sry Koopman et al. Notably, Sox9 expression increased drastically.

From pleasure to procreation, insecurity to inquisitiveness -- today's reasons for taking a roll in the hay seem to vary as much as the terms for the deed itself. Furthermore, mutations of this gene are responsible for XX sex reversal in goats polled intersex syndrome, PIS Pailhoux et al. Genetics of sexual development: Convincing evidence challenges us to reconsider the existing paradigm that describes ovarian development as a default system. Pleasure, stress relief , exercise , sexual curiosity, or attraction to a person Goal-based reasons: Notably, Sox9 expression increased drastically. Research by Uhlenhaut et al. To make a baby , improve social status for example, to become popular , or seek revenge Emotional reasons: Cultures differ markedly in what are considered to be 'appropriate' reasons for having or avoiding sex.

Why do you seek sex? Yet, some sexologists say, at the most basic level, there is only one true reason people seek sex. The idea that primary sexual determination defaults to female was proposed several decades ago and is primarily based on the observation that, in the absence of Sry , ovarian development takes hold. In , Janell Carroll and colleagues found that most college-aged males had casual sex for physical reasons without emotional attachments. Knockout of the gene prevented granulosa cell differentiation during development, leading to ovarian failure Schmidt et al. Sry, particularly, must be expressed within a specific time interval or ovarian development will take hold Bullejos and Koopman ; Hiramatsu et al. Person-centered sex is when you have sex to connect with the other person. In the case of both males and females, primary sex determination is not just a process that occurs during development but rather requires active regulation for the duration of adult life.
