Maternal Instinct Is Real, Not a Patriarchy Myth

Dr. Carole Hooven strongly disputes the claim that maternal instinct is a social construct created by the patriarchy. She argues that biology, not culture, drives the intense caregiving behavior seen in mothers across mammalian species.

Maternal instinct is evident in 95% of non-human mammals, where females are the primary caregivers.
Human mothers show hormonal and neurological mechanisms supporting maternal care.
The idea that maternal instinct is a myth undermines real biological differences.
Fathers can invest in children, but survival in ancestral environments depended more on mothers.

“There is a maternal instinct. We don't need to twist the facts of biology to support anybody's rights.”

Sex Is Not a Spectrum, Despite What You've Heard

Dr. Hooven argues that biological sex is binary in humans and most mammals, and that intersex conditions, while real, do not disprove the existence of two distinct sexes.

Humans, like most mammals, have two biological sexes.
Intersex conditions affect only about 0.02% of people and do not negate the male/female binary.
Even in rare intersex cases, individuals are still classified as male or female.
Recognizing two sexes does not limit gender expression or rights.

“Sex itself is not on a spectrum. The traits associated with sex can be on a spectrum, but sex itself is not.”

How Male and Female Orgasms Differ

Dr. Hooven explains that female orgasms are typically longer-lasting and full-body, while male orgasms are more intense but shorter and localized to the genitals. Trans people report distinct changes in orgasm quality when transitioning.

Female orgasms are more likely to be longer-lasting and full-body experiences.
Male orgasms are more intense at peak but shorter and localized to genitalia.
Trans people report distinct changes in orgasm quality when on testosterone.
A trans woman who de-transitioned appreciated both testosterone-driven and non-testosterone emotional ranges.

“A woman's orgasm is much more likely to be a longer-lasting full-body experience. Men's orgasm is more likely to have more intensity at the peak…”

Testosterone Reduces Emotional Expression Like Crying

Dr. Hooven notes that testosterone suppresses emotional expression, particularly crying. Trans men often report reduced crying on testosterone, while men coming off it experience a return to higher female-typical crying levels.

Testosterone greatly reduces crying and emotional expression.
Trans men report reduced crying after starting testosterone.
Coming off testosterone increases crying back to female-typical levels.
Anger remains the most accessible emotion on high testosterone.

“Going on testosterone usually stops or really greatly reduces crying. Coming off it increases crying back to typical female levels.”

Testosterone Shapes Behavior Before Socialization

Dr. Hooven explains that testosterone exposure in utero and shortly after birth permanently shapes brain development and behavior, leading to sex differences evident even in toddlers before significant socialization occurs.

Male babies have a testosterone spike shortly after birth that permanently changes the brain.
Sex differences in play and behavior appear before significant socialization.
Female rats given testosterone play like males; male rats deprived of it play like females.
Girls with high prenatal testosterone show more 'masculinized' play preferences.

“The huge differences we see between girls and boys come about because of differential exposure to testosterone in utero and shortly after birth.”

Female Sexuality Is More Fluid Than Male Sexuality

Dr. Hooven discusses evidence that female sexuality is more flexible and responsive to various stimuli, while male sexuality is more rigid and category-specific, as shown by physiological arousal studies.

Women's vaginas lubricate in response to all sexual stimuli, including non-human primates.
Men's erections correlate tightly with their stated orientation.
More women identify as bisexual compared to men.
Societal factors contribute, but biological fluidity in women appears real.

“Women's vaginas will lubricate to all sexual stimuli, including bonobos having sex, whereas men are very category-specific in their arousal.”

Trans Men Report Skyrocketing Libido on Testosterone

Dr. Hooven shares accounts from trans men who, after starting testosterone, experienced a dramatic and often shocking increase in libido and a shift in sexual focus toward physical attributes.

Multiple trans men reported libido 'going through the roof' after starting testosterone.
Many described being 'disturbed' by the intensity of their new sexual drive.
Sexual attention shifted from emotional connection to objectification of body parts.
This gave them empathy for the male experience of constant sexual motivation.

“They were shocked by it, they were disturbed by it... I get it now. I'm looking at this other person... I can't stop thinking about…”

What Is Post-Nut Clarity and Is It Real?

Dr. Hooven discusses 'post-nut clarity'—a period of emotional detachment or regret some men feel after sex—and suggests it may be an adaptive evaluation period, unlike typical female post-sex bonding tendencies.

Post-nut clarity refers to a man's post-sex period of emotional detachment or reassessment.
It may be an adaptive mechanism to evaluate mating choices and status.
Women, having higher reproductive costs, are more likely to seek pair-bonding after sex.
The phenomenon parallels postpartum evaluation periods in some cultures.

“After sex, a man might think: okay, let's reassess my options here. Do I really want to stick with this woman or see if there's…”

Grip Strength Is Best Predictor of Male Mating Success

Dr. Hooven highlights research showing that hand grip strength is the single strongest predictor of a man's number of sexual partners, outperforming facial masculinity, voice pitch, and even testosterone levels.

Grip strength is the best single predictor of male mating success.
It reflects overall health, strength, and testosterone effects.
It captures physical robustness better than other traits like height or voice pitch.
Stronger grip correlates with mood stability and lower depression in men.

“Grip strength is the single best predictor of the total number of mates that a man has throughout his life.”

Need to Normalize and Celebrate Male Puberty

Dr. Hooven reveals she's considering writing a book to help young men and society understand male puberty without stigma, celebrating it as a natural and powerful stage of development.

Male puberty is often stigmatized rather than celebrated.
A science-based book could help young men understand their changing biology.
Society should support healthy masculinity without shame.
Understanding testosterone's role can foster empathy and reduce judgment.

“I want to write a book that helps young men and those around them understand what it might be like and the challenges they have…”
