It is testimony to Simmons’hard-nosed empiricism that he pays more attention to questions from the traditional‘male perspective’ on why femalesmate multiply.

The Evolution of Polyandry: Sperm Competition, Sperm Selection, and Offspring Viability
- L. Simmons
- Biology
- 10 November 2005
A meta-analysis of available data suggests that polyandry, rather than multiple mating, can have a weak but significant general effect on embryo viability, as indicated by egg hatching success.

The results support the immunocompetence-handicap hypothesis for male faces in that masculine traits signalled health during adolescence, but suggest that any health-related evolutionary benefits obtained from preferences for attractive facial traits may be weak.
Sperm competition: linking form to function

It is shown that increased sperm length is unlikely to be driven by selection for increased swimming speed, and that the relative lengths of a sperm's constituent parts, rather than their absolute lengths, are likely to be the target of selection.

This review reviews the evidence in support of the contention that ROS production will constitute a primary and universal constraint in life-history evolution, and integrates the above suggestions into one life- history framework.
The evolution of polyandry: an examination of the genetic incompatibility and good‐sperm hypotheses
- L. Simmons
- Biology
- 1 July 2001
The adaptive significance of polyandry using the Australian field cricket Teleogryllus oceanicus is examined, with little evidence to suggest that females elevate their hatching success via fertilizing their eggs with sperm from genetically compatible males.
SPERM COMPETITION GAMES: A GENERAL MODEL FOR PRECOPULATORY MALE–MALE COMPETITION

- 1 January 2013
A general model of sperm allocation is developed that allows us to examine the effect of all forms of precopulatory competition on sperm allocation patterns and predicts that sperm allocation decreases if either the “mate‐competition loading,”a, or the number of males competing for each mating, M, increases.
