NOCTURNAL BIOACTIVE FSH PULSES ARE EVIDENT IN PRE (PERI) PUBERTAL BOYS

Nipple diameter in eastern Turkish pubertal boys.

Recommended body mass index cutoff values for overweight screening programs in Australian children and adolescents: comparisons with North America values. To our knowledge, only one report describing nipple diameters in pubertal boys has been published. 1 We studied 462 boys, aged 8–17 years, to determine if nipple diameter might provide measurable criteria for assessing sexual maturation durin...

Acute bone response to whole body vibration in healthy pre-pubertal boys

The skeleton responds to mechanical stimulation. We wished to ascertain the magnitude and speed of the growing skeleton's response to a standardised form of mechanical stimulation, vibration. 36 prepubertal boys stood for 10 minutes in total on one of two vibrating platforms (high (>2 g) or low (<1 g) magnitude vibration) on either 1, 3 or 5 successive days (n=12 for each duration); 15 control ...

Effect of metronidazole on spermatogenesis and FSH, LH and testosterone levels of pre-pubertal rats.

Metronidazole, a 5-nitroimidazole drug has been reported to decrease testicular weight, testicular and epididymal spermatid counts and causes abnormal sperm morphology with degeneration of seminiferous tubules with 6 weeks treatment of metronidazole (400 mg/kg, day). In contrast to DNA flow cytometry (FCM), the histological and gravimetric parameters do not allow a rapid, sensitive, objective a...

Variations in the pattern of pubertal changes in boys.

Development's tortoise and hare: pubertal timing, pubertal tempo, and depressive symptoms in boys and girls.

Although the sequence of pubertal maturation remains consistent across most individuals, the timing and tempo of development fluctuate widely. While past research has largely focused on the sequelae of pubertal timing, a faster tempo of maturation might also present special challenges to children for acclimating to new biological and social milestones. Using latent growth curve modeling, the pr...
