Experiments were conducted in the ewe to determine the effects of mating on the activity of the genital tract and on blood levels of oxytocin and cortisol. The activity of the uterus and cervix was recorded by electromyography, oxytocin was measured by radioimmunoassay, and cortisol by high performance liquid chromatography. Mating itself did not increase circulating oxytocin or cortisol; uterine motility remained unchanged during and after copulation but the cervix was significantly stimulated during teasing and after copulation. It is suggested that increased cervical activity resulting from adrenergic mechanisms may facilitate the generation of a cervical reserve of spermatozoa.
在母羊身上进行了实验，以确定交配对生殖道活动以及催产素和皮质醇血液水平的影响。通过肌电图记录子宫和宫颈的活动，用放射免疫分析法测定催产素，用高效液相色谱法测定皮质醇。交配本身并未增加循环中的催产素或皮质醇；交配期间和之后子宫活动保持不变，但在逗引期间和交配后宫颈受到显著刺激。有人提出，由肾上腺素能机制导致的宫颈活动增加可能有助于产生宫颈精子储备。
