加利福尼亚的科学家们发现了控制人类生育的关键性脑激素。这种激素为催乳素释放抑制因子(PIF),可抑制体内催乳素的产生,是影响人类生育的关键激素。科学家们说,PIF在脑内也许还有其它功能,它可能影响人的行为。上述发现有助于理解人类生殖的化学变化现象及过程。研究人员们确信,它将导致在新的避孕药(或用具)及生育药的生产和使用上的进展。 PIF产生于下丘脑。下丘脑是大脑对激素全面调控的关键部位。PIF能使脑垂体产生的催乳素减少,而催乳素则刺激妇女产乳。
Scientists in California have discovered the key brain hormones that control human reproduction. This hormone is a prolactin release inhibitory factor (PIF), can inhibit the production of prolactin in the body, is the key hormone affecting human reproduction. Scientists say PIF may have other functions in the brain that may affect human behavior. The above findings help to understand the phenomenon and process of chemical changes in human reproduction. Researchers are confident that it will lead to advances in the production and use of new contraceptives (or appliances) and fertility drugs. PIF is produced in the hypothalamus. The hypothalamus is a key part of the brain’s overall regulation of hormones. PIF can reduce the prolactin produced by the pituitary gland, while prolactin stimulates women to produce milk.
