Description

<p>This paper investigates the relationship between menstrual cycle regularity during college and the subsequent fertility of women who graduate from a physical education college（N＝496）and an education college (control group, N＝120).</p><p>The study investigated the state of menstruation during college, as well as pregnancies, deliveries, postpartum health, gynecological diseases, and climacteric symptoms occurring after college. The results were as follows:</p><p>1）There was no clear difference between the physical education group and the control group in terms of age at menarche, age at marriage, the number of pregnancies, and the ratio of infertility.</p><p>2）The rates of premature delivery, post-term delivery, stillbirth, and spontaneous abortion of the physical education group were high compared to those of the control group. In addition, abnormalities concerning pregnancy and delivery in the control group were high in comparison with those in the physical education group. However, the rates of premature delivery, post-term delivery, stillbirth, and spontaneous abortion were lower in both groups than in the general population.</p><p>3）No differences were observed between pregnancy, delivery, physical condition after giving birth, and the duration of labor in the physical education group and the control group.</p><p>4）The rate of irregular cycles and secondary amenorrhea during college was13.0% in the physical education group, and 16.1% in the control group. Two women who never had the menstruation during college were belonged to the physical education group.</p><p>5）It was apparent that infertility problems, infertility distress, spontaneous abortions, and secondary amenorrhea were more common for women with irregular cycles than for women who had regular menstruation cycles while they attended college.</p><p>These results suggest that the state of a woman’s menstrual cycles during college is related to her fertility in the future, especially regarding rates of infertility and spontaneous abortion.</p>
