Overview of the current data resources available in the SIG area

The hormonal and reproduction SIG has access to unique resources to address the early life origins of reproductive health and disease including:

  • Sex steroid measures obtained during pregnancy
  • Sex steroid measures from the umbilical cord at birth
  • Prospective data on age at menarche
  • Evaluation of menstrual history, ovarian morphology and timed ovarian sex steroids at aged 14-16 years
  • Hormonal contraceptive use
  • Pregnancy data

Overview of current/recent SIG activity

Recent activity from the hormonal and reproduction SIG has included:

  • Describing testicular function in a birth cohort of young men and defining the association between early life events and adult testicular function in young men.
  • Defining the association between metabolic phenotype, NAFL and PCOS.
  • Describing the association between age at menarche and cardiovascular risk factors in young women (Chi Le Ha et al, in preparation)
  • Defining the gold-standard for androgen measures in cord blood
  • Describing the association between umbilical cord androgen concentrations and a range of developmental outcomes in childhood
  • Describing the relationship between prenatal growth and developmental outcomes in childhood
  • Effects of antenatal exposure to steroids (androgens, estrogens and neurosteroids) and endocrine disrupters (BPA, phthalates) on sexual development, neurodevelopment and behaviour

Outline of SIG plans for next 5 years

  • To continue to monitor reproductive outcomes in order to determine the key early life factors which determine reproductive health in adulthood.
  • To establish the relationship between sex steroid exposures in early life and physical and emotional health in adulthood.
  • To collaborate with international groups to better understand genetic factors and gene-environment interactions in determining reproductive health outcomes.
