对31例月经规律妇女的36个周期于卵泡期、排卵前、排卵后及黄体中期各采血1次,用放免法测定血清泌乳素水平。结果表明:有正常排卵的34个周期血清泌乳素浓度平均12.22±6.56μg/L。在月经周期中泌乳素水平出现2个峰值,第一峰值在排卵前(14.75±5.03μg/L),第二峰值在黄体中期(16.31±6.90μg/L)。两峰值均明显高于卵泡期及排卵后,P<0.05,两峰值间无显著差异。 Thirty-six women with menstrual cycle had blood samples taken from follicular phase, anterior ovulation, ovulation and mid luteal phase respectively. Serum prolactin levels were measured by radioimmunoassay. The results showed that: 34 cycles of normal ovulation serum prolactin concentration average 12.22 ± 6.56μg / L. During the menstrual cycle, there were two peaks of prolactin level, with the first peak before ovulation (14.75 ± 5.03μg / L) and the second peak at mid-luteal phase (16.31 ± 6.90μg / L). Both peak values ​​were significantly higher than follicular phase and ovulation, P <0.05, no significant difference between the two peaks.
