Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Biological theory and empirical studies consistently support the conclusion that sexual selectivity differs between the sexes, largely driven by fundamental asymmetries in gamete size and parental investment.

The analysis

The claim that one biological sex is demonstrably more sexually selective than the other is well-supported by evolutionary biology, parental investment theory, and psychological studies on human mating strategies (e.g., anisogamy leading to sex-role divergence). Papers [0], [3], [7], and [10] provide direct theoretical and empirical backing for sex differences in selectivity. None of the retrieved papers refute the core premise that biological sex influences sexual selectivity.

Fromhage and Jennions (2016) formalize sexual selection theory and demonstrate that fundamental biological asymmetries (anisogamy) and parental investment drive divergence in sex roles and sexual selectivity.

The multiple perspectives review on sexual-economic exchange (2025) highlights that evolutionary models frame sexual dynamics as emerging from reproductive asymmetries where sexual access is regulated differently by sex.
