Anomaly of puberty or/and menstrual cycle

Anomaly of puberty or/and menstrual cycle (Orphanet code 180208) is a broad clinical grouping category used in Orphanet's classification system rather than a single discrete disease entity. It encompasses a range of rare disorders that affect the normal timing, progression, or characteristics of puberty and/or the regularity and function of the menstrual cycle. These conditions primarily affect the endocrine (hormonal) and reproductive systems, and may involve the hypothalamic-pituitary-gonadal axis, which is the central regulatory pathway controlling sexual maturation and reproductive function. Conditions grouped under this category include disorders of precocious (early) puberty, delayed puberty, absent puberty, primary or secondary amenorrhea (absence of menstruation), and other menstrual irregularities with an underlying genetic or rare disease etiology. Key symptoms vary depending on the specific underlying condition but may include early or late development of secondary sexual characteristics (breast development, pubic hair, testicular enlargement), absent or irregular menstrual periods, short or tall stature related to abnormal pubertal timing, and in some cases infertility. The body systems most commonly affected include the reproductive organs, the endocrine glands (particularly the pituitary and gonads), and skeletal development. Treatment depends entirely on the specific underlying diagnosis within this group. Options may include hormone replacement therapy, GnRH analogs to suppress or stimulate puberty as appropriate, surgical interventions for structural anomalies, and psychological support. Early diagnosis and management by a pediatric endocrinologist or reproductive specialist are important to optimize growth, sexual development, fertility potential, and quality of life. Because this is a classification category rather than a single disease, patients should seek information specific to their individual diagnosis.
