“…The use of alternative techniques, such as the use of transrectal ultrasound‐guided massage of the accessory sex glands (TUMASG), a technique reported to be effective in aoudad (Ammotragus lervia sahariensis) (Santiago‐Moreno et al. ) should be tested. Unfortunately, due to the low number of pampas deer available for research, advancement in the development of effective alternative techniques is slow in the species.…”

“…Other combinations, such as the method previously used plus inhalation of isoflurane anaesthesia (dos Santos et al 2010), or the addition of analgesic agents as fentanyl citrate (Asher et al 2011) should also be tested. The use of alternative techniques, such as the use of transrectal ultrasound-guided massage of the accessory sex glands (TUMASG), a technique reported to be effective in aoudad (Ammotragus lervia sahariensis) (Santiago-Moreno et al 2013) should be tested.

The aim of this study was to characterize the vocalizations produced during electroejaculation under general anaesthesia in pampas deer males and to determine whether the characteristics of those vocalizations differ in adult and young pampas deer males. Electroejaculation was applied to 13 adults (AM) and 13 young (YM) males under general anaesthesia. Vocalizations were digitally recorded, and the number and duration of vocalizations, the latency in relation to each voltage, the total time vocalizing, and the structure of the fundamental frequency (F0) [initial frequency (F(start)), maximal frequency (F(max)), minimal frequency (F(min)) and final frequency (F(end))] were analysed. No male vocalized with 0 V; the number of animals that vocalized increased at 2 and 3 V and increased again at 4, 5 and 6 V (p < 0.05). The latency time from the beginning of each series (each voltage) decreased until 4 V (p < 0.01). The number of vocalizations/voltage increased from 4 V (p < 0.05). The length of each vocalization and the total time during which animals vocalized were greater in YM than AM (p = 0.02 and p = 0.01, respectively). Similarly, the fundamental frequencies were higher in YM than AM (p ≤ 0.05). Overall, we concluded that the vocalizations emitted during electroejaculation in pampas deer under general anaesthesia are related to the voltage applied during the process. Young males vocalize more time, probably due to a greater sensibility to the electric stimulation. The differences in the characteristics of the vocalizations between adult and young males may be related to the anatomic differences in the neck of adult or young males.

“…The right testicle now had a normoechogenic echotexture, and had reached a diameter of 1.58 cm (the diameter of the left testicle was 1.97 cm) (Figure 3). The bulbourethral glands remained the same size, but the mean area of the seminal vesicles had increased to 0.26 cm 2 . The collected semen sample showed a very low sperm concentra- tion, and most sperm were non-motile (oligoasthenospermia).…”

“…Semen is obtained by transrectal ultrasound-guided massage of the accessory sex glands (TUMASG) combined with electroejaculation. 2 Anaesthesia is then reversed via the administration of 0.7 mg/kg yohimbine hydrochloride (Sigma, St. Louis, MO, USA) (half of the dose injected intravenously, the other half intramuscularly). The animals recover fully within 16 min.…”

Vet Med Open J. 2017; 2(2): 51-54. doi: 10.17140/VMOJ-2-116 ABSTRACTGonadotrophin deficiency, a condition usually present from birth, can cause delayed puberty in humans and domestic animals, but this has not been confirmed in wild mountain ruminants. During the rutting season (December), signs of sexual immaturity were detected in a 2.5 yearold male Iberian ibex (Capra pyrenaica) maintained in captivity. Cryptorchidism of the right testicle was diagnosed, along with complete adherence of the urethral process to the prepuce. The animal was treated with five injections of 500 UI hCG, administered intramuscularly over four weeks (two injections four days apart in the first week, and then one injection per week). Upon completion of the treatment, the right testicle completed its descent into the scrotum, and the urethral process detached from the preputial mucous membrane. A semen sample was collected which revealed oligoasthenospermia, confirming hCG to be at least partially effective in the stimulation of spermatogenesis in ibexes with gonadotrophin deficiency.

“…The sperm samples were obtained during the rutting season (November-December) using transrectal ultrasonic-guided massage of the accessory sex glands (TUMASG) combined with electroejaculation as previously described (Santiago-Moreno et al, 2013). Ultrasonic examination was performed using real-time transrectal ultrasonography employing a 7.5 MHz linear array probe (Prosound 2, Aloka CO., LTD, Tokyo, Japan).…”
