It has been argued that females should be able to choose parasite-resistant mates on the basis of the quality of male secondary sexual characters and that such signals must be costly handicaps in order to evolve. To a large extent, handicap hypotheses have relied on energetic explanations for these costs. Here, we have presented a phenomenological model, operating on an intraspecific level, which views the cost of secondary sexual development from an endocrinological perspective. The primary… 
Testosterone, immunocompetence, and honest sexual signaling in male red grouse
TLDR
It is suggested that comb size honestly indicates immunocompetence and males' ability to cope with certain parasites and females could thus benefit from choosing mates based on the expression of this sexual trait.
A tradeoff between immunocompetence and sexual ornamentation in domestic fowl.
TLDR
Results support the idea that a tradeoff with immune function may constrain the expression of secondary sexual ornaments, and compare comb size between male domestic chickens Gallus domesticus of lines divergently selected for antibody responses to sheep erythrocytes.
Bateman's principle and immunity

TLDR
An alternative hypothesis is proposed that explains many of the findings without relying on testosterone or other biochemical feedback loops, that males gain fitness by increasing their mating success whilst females increase fitness through longevity because their reproductive effort is much higher.
Immune system activation affects male sexual signal and reproductive potential in crickets
TLDR
The data support the parasite-mediated theory of sexual selection, suggesting that female's gain direct benefits by mating with males who are immune competent, and may therefore provide choosy females with a way to avoid mating with immune-compromised males.
A Novel Test of the Immunocompetence Handicap Hypothesis
TLDR
A novel test of the immunocompetence handicap hypothesis provides an explanation for the display of honest secondary sex characters as influenced by androgen levels, the immune system and its response, and parasite infection and burden, and lays important groundwork for the thorough study of the ICHH in future research.
Courtship and male ornaments as honest indicators of immune function
Sexual dichromatism and the immunocompetence handicap: an observational approach using Arctic charr
TLDR
It is shown that expression of red coloration in the salmonid Arctic charr is a sexually dimorphic character that reveals information of potential importance in sexual selection.
THE EFFECT OF PARASITES ON COURTSHIP DANCE IN THREESPINE STICKLEBACKS : MORE THAN MEETS THE EYE ?
TLDR
It is argued that the results nonetheless support the underlying assumption in Hamilton and Zuk's hypothesis, as fin size can be indicative of an individual's ability to tolerate parasites, and is closely related to a male's condition factor.
Bill colour and immunocompetence in the European blackbird
TLDR
The relation between immunocompetence and a secondary sexual trait may differ markedly depending on which component of the immune system is under consideration, and the results in relation to mechanisms involved in sexual selection are discussed.

Parasites and Mate Choice in Gray Treefrogs, Hyla versicolor
TLDR
Results of analyses of calling and mating behavior by male gray treefrogs in relation to their parasite infection levels failed to support the major within-species prediction of the Hamilton-Zuk model of sexual selection and calls into question one of the fundamental assumptions of the model.
Parasites And Male Ornaments In Free-Ranging And Captive Red Jungle Fowl
TLDR
A new analysis of female choice of uninfected controls versus experimentally infected roosters suggests that females prefer a multivariate array of traits perceived as a continuous, rather than categorical, variable.
Parasites and mate choice in red jungle fowl.
TLDR
Captive flocks of red jungle fowl experimentally infected with the intestinal nematode Ascaridia galli were used to test Hamilton and Zuk's hypothesis that parasites adversely affect male secondary sex characters and that females prefer unparasitized over parasitized males and that parasites have a disproportionately larger effect on ornamental traits.

TLDR
An explicit genetic model is presented that shows that male display can evolve as a consequence of female choice even when the display is not the immediate object of choice.
EVOLUTION OF CONDITION‐DEPENDENT SEX ORNAMENTS AND MATING PREFERENCES: SEXUAL SELECTION BASED ON VIABILITY DIFFERENCES
  • M. Andersson
  • Biology

TLDR
The possibility that the evolution of mating preferences and secondary sex traits can be based on heritable differences in viability is examined with a three‐locus model, based on a monogamous mating system that precludes such a Fisherian mating advantage being required.
Bat Predation and Sexual Advertisement in a Neotropical Anuran
TLDR
The role of predation in the evolution of the vocal repertoire of the frog Physalaetnus pustulosus is investigated and the hypothesis that male P. pustULostus that produce calls more attractive to females are also more prone to predation by T. cirrhosis is tested.
Sexual selection, natural selection and quality advertisement
TLDR
Both mating advantage and mortality disadvantage increase with ornament size, and balance at its optimal development, and if a given adornment reduces survival most in low quality phenotypes, the optimum increases with phenotypic quality.
