Sperm count in men has dropped over 50% since 1973, possibly due to phthalates (plastic softeners), and/or due to sedentary lifestyle.

Females are becoming more feminine:
Menarche has receded from 16.5 years to 12.5 years since 1880.

Females who experience puberty earlier have a stronger preference for masculine faces.

Females who experience puberty earlier have an earlier onset of anxiety disorders (i.e. higher neuroticism).

This might be affecting human sexual behavior:
Over 16 years (1999–2015), women’s orgasmic capacity has declined, from 56% of women experiencing orgasm in intercourse always or nearly always in 1999 to 46% in 2015.

The primary factor determining orgasm frequency in women is their partners’ physical attractiveness and masculinity.
