Semen characteristics of the adult male chimpanzee ( Pan troglodytes )
The chimpanzee, because of its similarities to the human, is especially valuable in studies of reproductive function. However, relatively little is known about the physiology of reproduction in the adult male chimpanzee. This study provides, for five adult male chimpanzees, baseline values for testicular volume without and with pressure and for cellular and biochemical characteristics of ejaculates collected by artificial vagina (AV). There was n…
Selected endocrine parameters of the adult male chimpanzee
This study provides baseline data on reproductive endocrine parameters of the male chimpanzee. A colony group of 47 male chimpanzees were classified by age as juvenile, ages 4–6 years (n = 7); adolescent, ages 7–9 (n = 9); and adult, ages 10–33 years (n = 31). Blood samples (n = 112) obtained from these animals [juveniles (n = ll), adolescents (n = 25), and adults (n = 76)] were analyzed for testosterone (T), luteinizing hormone (LH), and follicl…
Alterations in primate sperm motility with maturation and during exposure to theophylline
Micropuncture was used to collect pure suspensions of sperm from the caput and cauda regions of chimpanzee epididymides, which were analyzed with a Motion Analysis VP‐110. Sperm recovered from the caput region showed no forward motility. Incubation of these sperm with cauda epididymal fluid affected motility in 62%–90% of the sperm. Dilution of cauda sperm into buffer containing >50 mM theophylline resulted in immediate initiation of progressive …
Characterization of radiolabeled components of human sperm surface and seminal plasma
Externally oriented components on the human sperm cell surface and components in human seminal plasma were labeled by enzymatic iodination with lactoperoxidase and [ 125 I] NaI. SDS‐7.5% PAGE of labeled sperm surface resolved one minor and four major components with approximate molecular weights of 92, 72, 46, 30, and 20K daltons, respectively. SDS‐7.5% PAGE of labeled seminal plasma resolved five components with approximate molecular weights of …
