OBJECTIVE: Earlier studies have shown that maternal hormone secretion during late first or second trimester may be affected by gravidity. We examined the luteoplacental hormone secretion during 5-11 weeks of gestation in relation to gravidity.
METHOD: Forty-one naturally conceived pregnancies underwent weekly assessment of serum human chorionic gonadotrophin, progesterone and 17-OH progesterone, estradiol, testosterone, and pregnancy-associated plasma protein A levels. In addition, the volume and the vasculature of the dominant ovary with corpus luteum were assessed with the use of a 3-dimensional power Doppler ultrasonography. Areas under the curve for hormonal and ultrasonographic parameters were calculated.
RESULTS: Twenty-two out of the 41 women were pregnant for the first time. All the pregnancies were uncomplicated and resulted in term deliveries of appropriately grown newborns. During pregnancy weeks 5-11, the secretion (area under the curve) of human chorionic gonadotrophin (6.54 ± 0.03 vs 6.39 ± 0.05, p = 0.010), progesterone (3.49 ± 0.02 vs 3.36 ± 0.03, p = 0.003), and 17-OH progesterone (2.73 ± 0.03 vs 2.62 ± 0.03, p = 0.013) were higher in primigravid than in multigravid women. No other differences were detected between primigravid and multigravid women.
CONCLUSION: The placental function already differs between primigravid and multigravid women during the first weeks of pregnancy, which reflects the corpus luteal function. © 2012 John Wiley & Sons, Ltd.
