Amenorrhea is rarely presented as a manifestation of endocrinological disturbances in patients of chronic hydrocephalus. We describe two cases of secondary amenorrhea caused by hydrocephalus due to aqueductal stenosis. Two female patients of age 30 and 20 yr presented with amenorrhea and increasing headache. Magnetic resonance images revealed marked, noncommunicating hydrocephalus without any t...

Amenorrhea is the absence or abnormal cessation of the menses (1). Primary and secondary amenorrhea describe the occurrence of amenorrhea before and after menarche, respectively. The majority of the causes of primary and secondary amenorrhea are similar. Timing of the evaluation of primary amenorrhea recognizes the trend to earlier age at menarche and is therefore indicated when there has been ...

Of 410 cases of spontaneous or induced abortion in the first or second trimester that were followed up, 95 were infertile. 18 of these had amenorrhea and 12 had oligomenorrhea. Amenorrhea and oligorrhea were more prevalent among the women who were over 31. Amenorrhea, oligomenorrhea, and infertility were more frequent after spontaneous than after induced abortion. Asymptomatic tubal block r...

Although amenorrhea may result from a number of different conditions, a systematic evaluation including a detailed history, physical examination, and laboratory assessment of selected serum hormone levels can usually identify the underlying cause. Primary amenorrhea, which by definition is failure to reach menarche, is often the result of chromosomal irregularities leading to primary ovarian in...

BACKGROUND Hypergonadotropic hypoestrogenic infertility is the most burdensome complication for females suffering from classic galactosemia. In contrast, male gonadal function seems less affected. The underlying mechanism is not understood and several pathogenic mechanisms have been proposed. Timing of the lesion, prenatal or chronic post-natal, or a combination of both are not yet clear. MET...

Background: Premature ovarian failure (POF) is defined by the association of amenorrhea, hypoestrogenism and elevated (menopausal) levels of serum gonadotropins before age of 40 years-old. This condition affects approximately %1 of women under 40 years of age. Physiologic replacement of ovarian steroid hormones seems rational until the age of normal menopause. Temporary return of ovarian functi...

background: luteinizing hormone (lh) was secreted by the stimulating cells of the testes and ovaries in the anterior pituitary gland. the application of this hormone is in the treatment of men and women with infertility and amenorrhea respectively. m aterials and methods: in the present study the alpha and beta subunits of human lh gene were cloned into the pegfp-n1 expression vector and produc...

A thorough history and physical examination as well as laboratory testing can help narrow the differential diagnosis of amenorrhea. In patients with primary amenorrhea, the presence or absence of sexual development should direct the evaluation. Constitutional delay of growth and puberty commonly causes primary amenorrhea in patients with no sexual development. If the patient has normal pubertal...
