摘要:
Theory assumes that postcopulatory sexual selection favours increased investment in testes size because greater numbers of sperm within the ejaculate

摘要:
ong with conventional gray-scale and color Doppler sonography and post-operative pathology were compared. The results revealed that (i) the size of injured testis

摘要:
measured using relative testes size (RTS). Within populations, demographic and ecological processes may drastically alter the level of sperm competition
Data from: Resource quality affects weapon and testis size and the ability of these traits to respond to selection in the leaf-footed cactus bug

摘要:
The size of weapons and testes can be central to male reproductive success. Yet, the expression of these traits is often extremely variable. Studies

摘要:
t critical factor in determining paternity. Gamete production is directly related to testis size in most species, and is associated with both mating behavior
Data from: Bigger testes increase paternity in a simultaneous hermaphrodite, independently of the sperm competition level
