In an attempt to understand the cause for spontaneous infertility in female turkeys, sera were obtained from a flock suffering this condition. These sera, from hens of known fertility, were tested for anti-fertility actions by incubating semen in them. After incubation, semen was inseminated into unrelated recipient hens. In the first of two experiments, semen incubated in sera from high fertility hens (average 89%) produced a fertility level of 72.7% over an 8 week period while semen incubated in sera from sterile hens significantly reduced fertility to 52.3%. In a second experiment sera from sterile donors again caused a significant reduction in the fertilizing ability of sperm (56.3% for sera from sterile hens vs. 73.5% for sera from high fertility hens). These results indicate the presence of a factor(s) in the sera of sterile hens which may be causally related to their infertility.
为了弄清楚雌性火鸡自发性不育的原因，从患有这种病症的鸡群中采集了血清。这些血清来自已知生育能力的母鸡，通过在其中孵育精液来检测其抗生育作用。孵育后，将精液输精到不相关的受体母鸡体内。在两项实验的第一项中，在高生育能力母鸡（平均89%）的血清中孵育的精液，在8周期间产生了72.7%的生育水平，而在不育母鸡的血清中孵育的精液显著降低了生育能力，降至52.3%。在第二项实验中，不育供体的血清再次导致精子受精能力显著降低（不育母鸡血清为56.3%，高生育能力母鸡血清为73.5%）。这些结果表明，不育母鸡血清中存在一种或多种可能与其不育有因果关系的因素。
