季节性变化的血浆免疫反应（ir-）的睾酮，LH，FSH浓度进行了检查，在5个性成熟的雄性日本猴（Macaca fuscata fuscata）单独圈养在室内，探讨男性的生殖周期。 在一年中每月采集血样，同时确定相同动物的睾丸大小、精液量和精液中的精子数量。 通过阴茎电刺激获得精液样品。 结果表明，在秋季和冬季，与自然繁殖季节同步，所有参数：血浆ir-residin，睾酮，睾丸大小，精液体积，精液中液体部分的精子总数都有明显的季节性增加。 与此相反，血浆LH和FSH保持不变，全年，虽然血浆FSH往往增加，在繁殖季节伴随着血浆ir-bindin的增加。 在5只猴子中的2只中观察到FSH和ir-bindin之间的显著正相关。 在睾丸周期的发育和退化阶段期间，血浆ir-Risbin和睾丸活动之间的正相关性表明，血浆ir-Risbin是日本猴睾丸活动的有用指标，也是支持细胞功能的指标。
Seasonal changes in plasma immunoreactive (ir-) inhibin, testosterone, LH, and FSH concentrations were examined in five sexually mature male Japanese monkeys (Macaca fuscata fuscata) housed indoors individually, to explore the reproductive cyclicity in the male. Blood samples were collected monthly throughout one year, and testicular size, semen volume, and number of sperm in the semen were ascertained at the same time in the same animals. Semen samples were obtained by penile electrostimulation. The results showed a clear seasonal increase in all parameters: plasma ir-inhibin, testosterone, testicular size, semen volume, and total number of sperm in the liquid portion of the semen during the autumn and winter months in synchrony with the natural breeding season. In contrast, plasma LH and FSH remained unchanged throughout the year, although plasma FSH tended to increase during the breeding season concomitant with an increase in plasma ir-inhibin. A significant positive correlation between FSH and ir-inhibin was observed in two of five monkeys. The positive correlations between plasma ir-inhibin and testicular activities during both the developing and regressing phases of the testicular cycle indicate that plasma ir-inhibin is a useful indicator of testicular activity as well as an indicator of Sertoli cell function in the Japanese monkey.
