[…] in testosterone that occurs in the afternoon.[ 4-6 ] Screening for hypogonadism in the general population is not indicated.[ 4 ] Case finding in selected circumstances is, however, acceptable, such as when testing for low testosterone is part of the workup[bcmj.org]
Screening for Low Testosterone: A Diagnostic Workup The initial best screening test for the diagnosis of hypogonadism is an early morning serum total testosterone level. If it is 300 ng/dL, the patient should be considered hypogonadal.[pharmacytimes.com]
Diagnosis [ edit ] Diagnosing KS and other forms of CHH is complicated by the difficulties in distinguishing between a normal constitutional delay of puberty or a case of KS/CHH. [27] [4] [28] The diagnosis is often one of exclusion found during the workup[en.wikipedia.org]
Metastin is also believed to control the migration of trophoblastcells ( 29 ). However, it is unknown whether these features are relevant to the mechanisms leading to IHH in our patients.[pnas.org]
Reversal of hypogonadism may occur in some patients receiving gonadotropins; thus short periods of interruption of treatment are advised.[journals.lww.com]
It remains unclear whether there is an improvement in glycemic control or cardiovascular risk with treatment.[endocrineweb.com]

Treatment and prognosis Treatment is primarily aimed at restoring normal pubertal development and in some case normal fertility. The former can be achieved by administration of exogenous sex steroids, appropriate to the gender of the patient.[radiopaedia.org]
Prognosis Although an increased mortality rate in hypopituitary patients is well documented, the actual cause of the increased mortality is not clear. If relevant hormones are adequately replaced, prognosis in hypopituitarism is good.[patient.info]
Prognosis Prolonged amenorrhea can lead to infertility and other medical problems such as osteoporosis (thinning of the bones).[medical-dictionary.thefreedictionary.com]
Discussion The prognosis of inducing ovulation in patients of HH is favorable though they require high doses of hMG. The baseline FSH and LH values do not predict an individual patient's response to hMG.[fertilityscienceresearch.org]
Ovulation induction can be achieved either with pulsatile GnRH therapy or alternatively with gonadotropin injections (hCG, FSH, hMG) given at set intervals to trigger the maturation and release of the egg for natural conception. [37] Prognosis [ edit[en.wikipedia.org]
If levels of sex steroids, FSH, or LH are not clearly decreased, further studies based on family history to identify gene mutations may help determine the etiology of the patient’s clinical symptoms.(Table 1) Table 1.[clinicaladvisor.com]
If the patient has normal pubertal development and a uterus, the most common etiology is congenital outflow tract obstruction with a transverse vaginal septum or imperforate hymen.[aafp.org]
Our case reports suggest that maybe screening for hypogonadism in all HIV-infected men might help to understand its etiology.[edmcasereports.com]
This confirms a prior study of prepubertal men with gonadotropin deficiency (of diverse etiologies) also pre-treated with variable rFSH regimens before adding hCG [ 14 ].[em-consulte.com]
Epidemiology Taken from the results of one study [ 1 ] : The incidence of hypopituitarism is estimated to be 4·2 per 100,000 per year. The prevalence of hypopituitarism is estimated to be 29-45 per 100,000.[patient.info]

Similarly, taking exogenous estrogenic compounds may also increase the level of estradiol and prevent the correct diagnosis. Reference ranges vary with age and sexual developmental stages of the child.[clinicaladvisor.com]
Prevention Good obstetric care has reduced the incidence of postpartum hypopituitarism. Radiation therapy that minimises exposure to the pituitary gland reduces incidence and time of onset of hypopituitarism.[patient.info]
Prevention Primary amenorrhea caused by a congenital condition cannot be prevented. In general, however, women should maintain a healthy diet, with plenty of exercise, rest, and not too much stress, avoiding smoking and substance abuse.[medical-dictionary.thefreedictionary.com]
