Insights
Gonadotropin-releasing hormone analogs effectively increase adult height in early-onset central precocious puberty. Further research is needed for other uses and psychosocial effects.
Area of Science:
- Pediatric Endocrinology
- Reproductive Medicine
- Adolescent Health
Background:
- Central precocious puberty (CPP) treatment has been revolutionized by gonadotropin-releasing hormone (GnRH) analogs.
- Optimal use of GnRH analogs in CPP and other pediatric conditions requires clarification.
- A consensus conference was convened by the Lawson Wilkins Pediatric Endocrine Society and the European Society for Pediatric Endocrinology to address these issues.
Framework:
- A diverse group of 30 experts from North America and Europe, balanced by gender and seniority, participated.
- Evidence was graded using the US Public Health system, with expert opinion used when data were insufficient.
- Working groups addressed specific questions, with conclusions based on consensus or majority vote.
Implementation:
- Participants prepared and revised materials before the conference.
- Discussions and presentations led to a final consensus statement.
- The process ensured broad input and agreement among experts.
Implications:
- GnRH analog efficacy is undisputed for increasing adult height in early-onset CPP (girls <6 years).
- Further studies are required for psychosocial effects of CPP and GnRH analog impact.
- Concerns like weight gain or bone density loss were not supported by the consensus; routine use beyond CPP needs more investigation.
Objective:
Gonadotropin-releasing hormone analogs revolutionized the treatment of central precocious puberty. However, questions remain regarding their optimal use in central precocious puberty and other conditions. The Lawson Wilkins Pediatric Endocrine Society and the European Society for Pediatric Endocrinology convened a consensus conference to review the clinical use of gonadotropin-releasing hormone analogs in children and adolescents.
Participants:
When selecting the 30 participants, consideration was given to equal representation from North America (United States and Canada) and Europe, an equal male/female ratio, and a balanced spectrum of professional seniority and expertise.
Evidence:
Preference was given to articles written in English with long-term outcome data. The US Public Health grading system was used to grade evidence and rate the strength of conclusions. When evidence was insufficient, conclusions were based on expert opinion.
Consensus Process:
Participants were put into working groups with assigned topics and specific questions. Written materials were prepared and distributed before the conference, revised on the basis of input during the meeting, and presented to the full assembly for final review. If consensus could not be reached, conclusions were based on majority vote. All participants approved the final statement.
Conclusions:
The efficacy of gonadotropin-releasing hormone analogs in increasing adult height is undisputed only in early-onset (girls <6 years old) central precocious puberty. Other key areas, such as the psychosocial effects of central precocious puberty and their alteration by gonadotropin-releasing hormone analogs, need additional study. Few controlled prospective studies have been performed with gonadotropin-releasing hormone analogs in children, and many conclusions rely in part on collective expert opinion. The conference did not endorse commonly voiced concerns regarding the use of gonadotropin-releasing hormone analogs, such as promotion of weight gain or long-term diminution of bone mineral density. Use of gonadotropin-releasing hormone analogs for conditions other than central precocious puberty requires additional investigation and cannot be suggested routinely.

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
