A comparative study on testicular microstructure and relative sperm production in gorillas, chimpanzees, and orangutans
We performed histological analyses for comparing testicular microstructure between the gorilla, chimpanzee, and orangutan. Testicular samples were obtained by autopsy or biopsy from 10 gorillas, 11 chimpanzees, and 7 orangutans from several zoos and institutes. The seminiferous epithelia were thick in the chimpanzee and orangutan but thin in the gorilla. Leydig cells in the interstitial tissue were abundant in the gorilla. The acrosomic system wa…
Testicular histological examination of spermatogenetic activity in captive gorillas ( Gorilla gorilla )
To clarify the reproductive state of male gorillas, we performed histological examinations on the testicles of 10 male gorillas ( Gorilla gorilla ). The testicular samples were obtained by autopsy, and ordinal histological preparations were made for light microscopy. The poor spermatogenesis of this species was characterized by the following findings: First, spermatogenesis was evident in only four samples. Meiosis progressed in two samples, but …

A Comparative Study on Histology of Testes in Macaca nemestrina, M. fascicularis and M. fuscata
Seasonal changes in spermatogenic cell degeneration in the seminiferous epithelium of adult Japanese macaques (Macaca fuscata fuscata)

Seasonal changes in the spermatogenic epithelium of adult Japanese macaques (Macaca fuscata fuscata)
Preliminary Report on Histological Characteristics of Male Reproductive Organs in Senile Japanese Macaques
Histological characteristics of male reproductive organs were observed macrographically and microscopically in Japanese macaques aged 20 years old or more. As the senility proceeded, testicular weight and the diameter of the seminiferous tubules decreased. Likewise, the weights and epithelial heights of the seminal vesicle and prostate gland decreased in old males. Histologically, a proliferation of interstitial tissue was notable in every organ …
Social play and sexual behavior of the bonobo (Pan paniscus) with special reference to flexibility
Longitudinal studies on annual changes in plasma testosterone, body weight and spermatogenesis in adult Japanese mankeys (Macaca fuscata fuscata) under laboratory conditions
Male aggression and the sexual behavior of Japanese monkeys
Correlation Between Fluctuations of Testosterone Levels in Systemic Circulation and Sexual Behavior in Intact Female Japanese Monkeys in the Laboratory Condition
Heterosexual interactions of pairs of Japanese monkeys were studied in connection with fluctuations of testosterone concentrations in blood plasma of females, using seven intact adult females and two males. Blood was collected from the females daily or with a few days interruption. Testosterone, estradiol-17β, and progesterone in blood plasma were determined by radioimmunoassay. The behavioral records were obtained through heterosexual pairing te…
Diurnal Variations in Plasma Testosterone and Cortisol in the Male Japanese Monkey
Under daily photoperiods of 12 or 6 hours in August, circadian rhythms of secretion of testosterone and cortisol in the male Japenese monkey were investigated. Plasma testosterone levels increased at night and fell in the morning
