Gynaecology problems in puberty
Publication date: Available online 14 June 2019Source: Best Practice & Research Clinical Endocrinology & MetabolismAuthor(s): Sonia R. Grover, DirectorAbstractWith the onset of puberty a range of problems may be encountered by the young girl. Some of these include a range of gynaecological issues relating to delayed onset of puberty, delayed menarche, atypical pubertal changes and the identification of anomalies of the genital tract. The distinction between physiological events and pathological problems is important to avoid unnecessary distress and anxiety. The onset of cyclic hormonal changes also provokes a numb...
