A homozygous R262Q mutation in the gonadotropin-releasing hormone receptor presenting as constitutional delay of growth and puberty with subsequent borderline oligospermia.

CONTEXT The GnRH receptor plays a central role in regulating gonadotropin synthesis and release, and several mutations in the GNRHR gene have been reported in patients with idiopathic or familial forms of isolated hypogonadotropic hypogonadism (IHH). OBJECTIVE The objective of the study was to investigate whether partial loss-of-function mutations in the GnRH receptor might be responsible for...

TREATMENT OF PRECOCIOUS PUBERTY BY A LONG-ACTING GONADOTROPIN-RELEASING HORMONE ANALOGUE IN CHILDREN

The GnRH analogue has been shown to be effective in the treatment of precocious puberty when given as a daily subcutaneous injection. We studied the effectiveness of a long-acting GnRH analogue, Triptoreline, for the treatment of central precocity, by suppressing gonadotropin and estradiol secretion in three children with true precocious puberty. One month after single dose intramuscular i...

Treatment of constitutional delay of growth and puberty with oxandrolone compared with growth hormone.

The effects of oxandrolone or biosynthetic human growth hormone (r-hGH) on the growth of 26 boys with constitutional delay of growth and puberty were studied. Both regimens increased growth rate twofold, oxandrolone to a greater extent than r-hGH. We conclude that oxandrolone is a more effective method of increasing growth rate in such children.

The genes associated with gonadotropin-releasing hormone-dependent precocious puberty

Human puberty is a complex, coordinated biological process with multiple levels of regulations. The timing of puberty varies greatly in children and is influenced by both environmental and genetic factors. The key genes of pubertal onset, KISS1, GPR54, GNRH1 and GNRHR, may be major causal factors underlying gonadotropin-releasing hormone-dependent precocious puberty (GDPP). Two gain-of-function...

The psychological outcome of constitutional delay of growth and puberty.

Does being of short stature (SS) matter? Growth studies are important because endocrinologists need to be able to give not only diagnostic but also prognostic indication to those of SS, and give advice for or against treatment. Studies on body height may give significant insight into the behavioural-hypothalamic-pituitary axis underlying the surface effect on social behaviour. This research pre...
