Stress fractures are common overuse injuries in athletes, especially in long-distance runner, jumping sports and gymnastics in female athletes. The pathology of stress fracture mainly includes repeated biomechanical loading, which leads to bone micro-damage and failure of bone structure. Female athlete triad(FAT), which includes low energy availability with or without an eating disorder, functional hypothalamic amenorrhea, and osteoporosis, is a serious healthcare concern in female athletes. For prevention and treatment of stress fracture, management of biomechanical factors modifying the load applied to a bone is important, and especially in female athletes, management for FAT is one of the important factors...

For development of the bone during adolescence, the increased estrogen plays an important role especially in young women as well as GH/IGF-Ⅰ system. Although primary amenorrhea can be caused by various pathological factors, almost of cases have a dysfunction of estrogen secretory systems. For Turner syndrome, which is well-known disease with primary amenorrhea,it is generally recommended that the estrogen therapy is started at adolescence and gradually increased up to adult dose level. Recently studies about the adequate dose of estrogen and the adequate age of adult dose in Turner syndrome revealed that intervention with adult dose of estrogen is required as soon as possible for gaining better bone mineral...

BACKGROUND: Ovarian granulosa cell tumors (GCTs) are the most common type of potentially malignant ovarian sex cord-stromal tumor. GCTs often produce estrogen and/or progesterone; consequently, symptoms related to hyperestrogenism are common at diagnosis. Nonspecific symptoms or signs associated with this neoplasm include amenorrhea and changes in various sex hormone levels, which can be hard to diagnose or explain. The aims of this report were to describe a case of GCT with rare presentations and to review the pertinent literature...

OBJECTIVES: Central (hypogonadotropic) hypogonadism in women could be a cause of persistent amenorrhea and hypoestrogenemia as observed in postmenopause. This study aimed to compare the clinical, hormonal and biochemical features in women with non-physiological (central hypogonadism) and physiological (postmenopause) hypoestrogenemia. METHODS: A total of 161 young women, median age 24.9 years (interquartile range (IQR) 21.2; 30.5) with central hypogonadism (with isolated hypogonadotropic hypogonadism, n = 76, and with hypopituitarism, n = 85), 53 healthy young women, median age 23...

Jill Thein-Nissenbaum, Erin Hammer
Since the passage of Title IX in 1972, female sports participation has dramatically increased. The benefits of physical activity, including decreased risk for heart disease and diabetes as well as improved body image and self-esteem, far outweigh the risks. However, a select population of adolescent and young adult females may experience symptoms related to the female athlete triad (Triad), which refers to the interrelatedness of energy availability, menstrual function, and bone mineral density (BMD). These conditions often manifest clinically as disordered eating behaviors, menstrual irregularity, and stress fractures; an individual may suffer from 1 or all of the Triad components simultaneously...

Primary ovarian insuffiency (POI), which accounts for female infertility, is characterized by amenorrhea before the age of 40 and high serum level of follicular stimulating hormone (>40 U/L) at two measurements taken at least one month apart. The disorder is believed to have a strong genetic component. A large number of candidate genes have been proposed, though few of them were extensively studied. With the rapid evolvement of genome sequencing technology, recent research raised the possibility that the genes involved in essential steps of meiosis such as chromosome synapsis and recombination play an important role in the pathogenesis of POI...

Androgen insensitivity syndrome is the most common cause of male pseudohermaphroditism and the third most common cause of primary amenorrhea. This genetic alteration is a consequence of inherited defects on the X chromosome causing total or partial damage to the intrauterine virilization process due to functional abnormalities in the androgen receptors. The present report describes a 22-year-old patient with a female phenotype and a 46, XY karyotype, presenting with bilateral inguinal tumors. The tumors were surgically removed at the Santa Casa de Misericórdia Hospital in Vitória, Espírito Santo, Brazil...

Turner's syndrome is a chromosomal disorder with 45 X0 due to absence of a set of gene from the short arm of X chromosome. The incidence of Turner's syndrome is 1 in 2500 live births. Primary amenorrhea is well known in Turner's syndrome, the reason being streak ovaries; but mullerian agenesis as a cause of primary amenorrhea in Turner's syndrome is a very rare entity. The incidence of Turner's syndrome associated with mullerian agenesis is extremely rare as there is only a hand full of cases reported in literature...
