[Disorders of the menstrual cycle in women after entering military training. IV. FSH, LH, prolactin, estradiol, progesterone and cortisol in the first week after beginning training].

The authors investigated the hormonal levels of FSH, LH, oestradiol, cortisol and progesterone in women after entering a military training contre. The specimens were collected on the fourth day after admission to the Centre and the results correlated with later "separation" disorders of the menstrual cycle in these women. The authors did not find differences in the mean levels of any hormone in normally regularly menstruating women and in women with disorders of the cycle. They found, however, a significantly higher variance of LH and oestradiol levels in women with disorders of the cycle. When investigating the correlation of different hormone levels, they found a significant positive correlation of FSH:LH, LH:oestradiol, FSH:oestradiol, prolactin:cortisol, and an indirect correlation of LH:cortisol.
