TLDR
It is concluded that the cloacal gland may be considered as an external indicator of testicular function of the birds and used as a simple and effective tool to predict the fertilizing ability of an individual male in view of the very small semen ejaculate that is very difficult to collect and evaluate for fertility.About:

Reproductive dysgenesis in wildlife: a comparative view
TL;DR: It is suggested that male susceptibility to the androgynizing influences of environmental contaminants originates in the sexually undifferentiated embryo, which, in almost all species, including humans, consists of bipotential reproductive tissues.

TL;DR: It can be concluded that moderate supplementation of dietary Vit.

Genetic association between sexual maturity and weekly live-weights in laying-type Japanese quail
TL;DR: Sexual size dimorphism can be explained by the differences in pattern of heritability and correlation estimates between reaching sexual maturity and live weights for males and females.

Relationship of cloacal gland with testes, testosterone and fertility in different lines of male Japanese quail.
TL;DR: It may be concluded that area of cloacal gland in Japanese quail is positively correlated with testicular weight, level of testosterone in plasma and fertility, and may provide a valuable non-invasive tool for predicting the fertilizing ability of individual male bird.

History of artificial insemination in poultry, its components and significance
TL;DR: Currently, the technique of AI in most of the poultry species is well developed; however, there is a need for successful development programme of this technique in non-domesticated birds to assist in creating viable, self-sustaining populations of critically endangered species.

Photoperiodic Control of the Cloacal Gland of the Japanese Quail
TL;DR: The cloacal protrusion may serve as a convenient external index of androgen, permitting repeated measurement without operation on or killing of the animal.

Rate of testicular maturation, in relation to gonadotrophin and testosterone levels, in quail exposed to various artificial photoperiods and to natural daylengths
B. K. Follett,S. L. Maung +1 more
TL;DR: The rate of photoperiodically induced testicular growth was proportional to the levels of FSH, and possibly also testosterone, in the circulation, and the hormone profiles offer an explanation for the differential rates oftesticular growth.
Journal ArticleDOI
Mechanisms for the Testicular Hypertrophy Which Follows Hemicastr ation
TL;DR: Changes in serum FSH and not intratesticular testosterone are associated with the testicular hypertrophy which follows unilateral castration of immature animals, and the increase in testicular weight is primarily the result of an increase in cell number.
