Background: The anogenital distance (AGD) is a well-known measure in rodents used to distinguish male and female pubs. Likewise, AGD display sex-specific differences in humans. It is considered a postnatal readout of early androgen exposure in fetal life. Thus, in postnatal life AGD is longer in boys than in girls, reduced in infants born with cryptorchidism and hypospadias as well as in boys exposed to anti-androgenic agents in fetal life. However, little is ...

Prenatal exposure to paracetamol is associated with smaller testis volume and decreased levels of steroid metabolites during infancy in healthy males: A COPANA cohort study of 287 boys

Background: Paracetamol is bought over the counter and frequently used by pregnant women. Studies suggest that paracetamol is endocrine-disruptive, affecting for example germ cell proliferation. Fetal male masculinization is initiated in early gestation (GW 8-14).Primary aim: To assess if prenatal exposure to paracetamol was associated with testicular function.Design: Prospective, ...

Ultrasonographic Evaluation of Ovarian and Uterine Morphology in Minipuberty and Associations with Reproductive Hormones: A COPANA Cohort Study of 302 infant girls.

Background: Minipuberty is considered an essential period for early diagnosis of endocrine disorders and reproductive organ maturation. While the complex dynamics of female reproductive hormones during minipuberty was recently described, detailed evaluation of ovarian and uterine morphology in relation to circulating levels of reproductive hormones remains to be elucidated.Aim: Report normative values of ovarian and uter...

Prenatal exposure to paracetamol is associated with reduced uterine volume at infancy - A COPANA Cohort study of 302 healthy girls

Background: Paracetamol is the preferred analgesic and antipyretic during pregnancy. Experimental studies suggest that in-utero exposure to paracetamol disrupts ovarian follicle formation and future ovarian function. This may secondarily affect uterine growth. Female minipuberty is characterized by HPG activity and follicle maturation, however individual levels of reproductive hormones fluctuate considerably.Primary Aim:...
