In Vivo	(d(CH2)51,Tyr(Me)2,Thr4,Orn8,Tyr-NH29)-Vasotocin (50-1000 ng; Intra-MPOA; 1 μL) 抑制大鼠雄性性行为的某些方面[1]。 (d(CH2)51,Tyr(Me)2,Thr4,Orn8,Tyr-NH29)-Vasotocin (100 ng; i.c.v.; 1 μL) 可有效抑制雄性大鼠交配行为后的痛觉减退[2]。 Animal Model: Adult Long–Evans/Blue-Spruce rats[1] Dosage: 50 ng, 200 ng, and 1 μg Administration: Intra-MPOA (medial preoptic area) injection, 1 μL Result: Significantly increased intromission latency and anogenital investigation at 1 μg dose. Significantly decreased intromission ratio (2) at all doses. Animal Model: Adult male and female Long-Evans rats (8 weeks old, 220–260 g BW)[2] Dosage: 100 ng Administration: Intracerebroventricular injection, 1 μL Result: Was effective in reducing pain threshold heightened by copulatory behavior.
