Minipuberty is the second phase of physiological activation of the reproductive axis, playing a role in the postnatal development of sexual organs. The course of female minipuberty was found to be affected by low maternal vitamin D status and hypothyroidism during pregnancy. The aim of the current study was to assess the hormonal profile and the size of sexual organs in daughters of mothers with gestational diabetes mellitus. The study included three matched groups of infant girls: daughters of healthy women without metabolic disorders during pregnancy (group 1), daughters of women with poorly controlled gestational diabetes mellitus (group 2), and daughters of women with gestational diabetes mellitus adequately controlled during pregnancy (group 3). Urinary levels of gonadotropins, salivary levels of estradiol, testosterone, DHEA-S and progesterone, ovarian volume, uterine length and breast diameter were measured from postnatal month 1 to postnatal month 18. Concentrations of FSH, LH and estradiol were higher, while concentration of progesterone was lower in group 2 than in the remaining groups. There were no between-group differences in concentrations of testosterone and DHEA-S. Levels of LH, FSH, estradiol and progesterone correlated with maternal whole-blood levels of glycated hemoglobin. Group 2 was also characterized by the longest detection periods for LH and estradiol. Ovarian volume, uterine length and breast diameter were greater in group 1 than in the remaining two groups. Over the entire observation period, there were no differences in hormone levels and sizes of the sexual organs between groups 1 and 3. The obtained results suggest that poorly controlled, but not well controlled, gestational diabetes mellitus affects the course of female minipuberty.
