Predictors of reproductive and non-reproductive outcomes of gonadotropin mediated pubertal induction in male patients with congenital hypogonadotropic hypogonadism (CHH).

PURPOSE: To investigate predictors of testicular response and non-reproductive outcomes (height, body proportions) after gonadotropin-induced puberty in congenital hypogonadotropic hypogonadism (CHH). DESIGN: A retrospective analysis of the puberty induction in CHH male patients, undergoing an off-label administration of combined gonadotropin (FSH and hCG). METHODS: Clinical and hormonal evaluations before and during gonadotropin stimulation in 19 CHH patients genotyped by Targeted Next Generation Sequencing for CHH genes; 16 patients underwent also semen analysis after gonadotropins. RESULTS: A lesser increase in testicular volume after 24 months of induction was significantly associated with: (I) cryptorchidism; (II) a positive genetic background; (III) a complete form of CHH. We found no significant correlation with the cumulative dose of hCG administered in 24 months. We found no association with the results of semen analyses, probably due to the low numerosity. Measures of body disproportion (eunuchoid habitus and difference between adult and target height: deltaSDSth), were significantly related to the: (I) age at the beginning of puberty induction; (II) duration of growth during the induction; (III) initial bone age. The duration of growth during induction was associated with previous testosterone priming and to partial forms of CHH. CONCLUSIONS: This study shows that a strong genetic background and cryptorchidism, as indicators of a complete GnRH deficiency since intrauterine life, are negative predictors of testicular response to gonadotropin stimulation in CHH. Body disproportion is associated with a delay in treatment and duration of growth during the induction, which is apparently inversely related to previous androgenization.

Hormonal therapy in a patient with ovarian agenesis and possible SLE: a choice to be made.

Systemic lupus erythromatosus (SLE) is an autoimmune disease, which affects mainly women in the reproductive age and is influenced by hormonal changes. Therefore, hormone supplementation for patients with SLE either as contraceptives or as postmenopausal supplementation remains a controversial issue. Herein, we report a case of a 22-year-old woman with a history of ovarian agenesis, treated for several years with hormone therapy in order to reduce the risk of osteoporosis and other estrogen-deficient disorders. At the current evaluation, she met 3 of 11 diagnostic criteria for SLE along with a strong familial autoimmune predisposition. Precipitation of SLE in patients treated with hormonal therapy has been previously described. This prompted us to seek alternative drug therapies that prevent both the onset of overt SLE as well as the progression of estrogen-deficient phenomena. This unique case illustrates the dilemma of using hormone therapy in patients at risk to develop SLE and the current therapeutic alternatives.

[Adverse effect of environmental endocrine disruptors on gonadal development of prepubertal male rats and therapeutic effect of bushen tianjing recipe on it].

OBJECTIVE: To verify the antagonistic effect of Bushen Tianjing Recipe (BTR) on environmental endocrine disruptors (EEDs) induced gonadal dysgenesis (GD) Sprague-Dawley (SD) male rat model. METHODS: Totally 70 3-week-old male SD rats were randomly divided into seven groups, i.e., the control group (fed with corn oil), the model A group [di-2-ethylhexyl-phthalate (DEHP) 500 mg/kg], the CM A group (fed with DEHP 500 mg/kg + BTR 40 mL/kg), the exposed group B (fed with CYP 80 mg/kg), the CM B group (fed with CYP 80 mg/kg + BTR 40 mL/kg), the model C group [fed with DEHP 500 mg/kg + CYP 80 mL/kg], the CM C group (DEHP 500 mg/kg + CYP 80 mg/kg + BTR 40 mL/kg), respectively, 10 in each group. All were administered with corresponding medication by gastrogavage, once daily, for total 30 days. Rats were killed 24 h after the last administration, and their body weight and wet testis weight were weighed. The coefficient of testis was calculated. The serum testosterone (T) level was measured by chemiluminescent immunoassay. The histopathologic tissue was prepared. The ultrastructural changes of genital cells were observed by electron microscope. RESULTS: Compared with the control group, there was no statistical difference in the body weight increase among all groups (P > 0.05). The time of testicular descent and preputial separation were significantly delayed in each exposed group (P < 0.01). In the exposed group A and the exposed group C, the wet weight of the testes was reduced and serum T level decreased (P < 0.01). The coefficient of testis significantly decreased in the exposed group A (P < 0.01). Compared with corresponding model group, the time of testicular descent and preputial separation were significantly fore-laid in each corresponding CM group (P < 0.01). The weight of the testes, the coefficient of testis, and the serum T level increased in the CM A group (P < 0.01). The serum T level obviously increased in the CM B group (P < 0.05). CONCLUSIONS: The GD rat model was successfully duplicated by using DEHP. EEDs were proved to have significant anti-androgen activities. BTR was verified to have significant antagonistic to its anti-androgen effect.

Live birth after blastocyst transfer following only 2 days of progesterone administration in an agonadal oocyte recipient.

In oocyte donation cycles where hormone replacement is given to recipients, progesterone administration is necessary to induce the luteal phase and synchronize the endometrium with the embryo stage. Most studies suggest that 5-7 days of progesterone are needed to prepare the endometrium for a day-5 embryo transfer and provide optimal implantation rate. This paper reports a case where an agonadal oocyte recipient received only 2 days of progesterone prior to the embryo transfer of a day-5 embryo. She subsequently had a clinical pregnancy and a live birth.

Mutation of the MIF type II receptor in two brothers.

The Müllerian inhibiting factor (MIF) is responsible for regression of Müllerian ducts during male sexual differentiation. Mutations in MIF or its type II receptor lead to persistence of the uterus and Fallopian tubes in male children--i.e., persistent Müllerian duct syndrome (PMDS). Both are rare autosomal recessive disorders. We report a 7-month-old male infant who underwent inguinal herniorrhaphy. Remnants of vas deferens and gonads with macroscopic characteristics of ovaries, along with Fallopian tubes and a rudimentary uterus, were found. Karyotype confirmed male sex. Molecular genetics revealed the most frequent MIF type II receptor gene mutation--27 bp deletion. Investigation of the older brother presenting bilateral cryptorchidism at 7 years of age led to similar clinical findings and the same mutation. We report here an MIF type II receptor mutation in two brothers, with the particularity that the surgical findings in the younger son initiated the diagnostic process in both children.

Surgical, medical and psychological dilemmas of sex reassignment: report of a 46,XY patient assigned female at birth.

This is a report of a 16 year-old 46,XY male who was reassigned female and had feminizing surgery during infancy because of what was judged to be inadequate genital masculinization. This patient had a dysgenetic testis that was shown to be producing testosterone during infancy. Although initially the reassignment appeared to be successful, psychological problems became progressively more severe during childhood to incapacitation by age 10 years. After it was verified that he had a male sexual identity, reassignment as male began, initially by living as a boy, then with testosterone therapy. Staged phalloplasty surgery was begun at age 16 years. Currently he has an adult-sized penis, although its function is not yet clear. Sadly, none of the steps to align his sex assignment to his perception as male has significantly alleviated his psychological issues and he continues to be severely impaired and socially compromised. Major issues include the crippling psychiatric disease that is resistant to psychotherapy and surgical problems with phalloplasty after surgery at infancy that involved reduction of the phallus with recession of the glans to the typical clitoral location. The glans was left intact at the anterior base of the phallus. Genital responsiveness during sexual activity and satisfaction are as yet unknown.

Prevalence of autoantibodies associated with thyroid and celiac disease in Ullrich-Turner syndrome in relation to adult height after growth hormone treatment.

A prospective, multicenter study of patients with Ullrich-Turner syndrome (UTS) was conducted to estimate the prevalence of autoantibodies to tissue transglutaminase (tTg), thyroid stimulating hormone receptor (TSH-R), thyroglobulin (TG) and thyroid peroxidase (TPO) in relation to adult height after long-term growth hormone (GH) treatment. Out of 347 near-adult (> 16 years) patients with UTS from 96 German centers, whose longitudinal growth was documented within the Pharmacia International Growth Study (KIGS), 188 returned for a standardized follow-up visit at a median chronological age of 18.7 (16.0-23.6) years (bone age > 15 years). Serum samples of 120 patients were obtained for central measurements of TSH, thyroxine (T4) and free T4 and autoantibodies by standard immunoassays. Information regarding thyroid disease, karyotype and anthropometric data was extracted from the KIGS database. Thirty-six percent of the patients with UTS had positive TG and/or TPO autoantibodies and 4% had positive tTg autoantibodies, whereas 2% had positive TG and/or TPO autoantibodies as well as positive tTg autoantibodies. TSH-R autoantibodies were undetectable in all patients. The detection of autoantibodies was unrelated to a specific karyotype. Median height standard deviation scores (SDS, UTS) at start of GH treatment (0.43; -1.07, 1.85) and at follow-up (1.36; -0.11, 2.57) were comparable in all patients independent of their antibody status. The total deltaheight SDS, however, was higher in patients with negative autoantibody titers (1.08; -0.03, 2.25) compared to those with positive antibody titers (0.68; -0.44, 1.82; p < 0.01). Our study confirms the high prevalence of autoantibodies in patients with UTS predisposing them to autoimmune thyroid disease and celiac disease, and indicates for the first time that autoimmune pathologies may interfere with GH therapy and thus compromise final height. Therefore, medical care for patients with UTS should routinely include screening for these autoimmune disorders in order to assure early detection and appropriate treatment.

A case of torsion of a mucinous cystadenoma in triple-X syndrome with pure gonadal dysgenesis.

Triple-X female characterized by primary amenorrhea and pure gonadal dysgenesis is extremely rare. We present a patient of triple-X syndrome who has not had menarche or the development of the secondary sexual characteristics. She had a hypoplastic uterus and streaked gonads on both sides with a twisted mucinous cystadenoma in the right adnexa.

[Gonadal dysgenesis associated with Mayer-Rokitansky-Küster-Hauser syndrome: a case report]. / Association dysgénésie gonadique et syndrome de Rokitansky Kuster Hauser: à propos d'un cas.

Gonadal dysgenesis with female phenotype is defined as the absence or insufficient development of the ovaries. Hypogonadism or impuberism are variable, depending on the degree of gonadal development. Mayer-Rokitansky-Küster-Hauser syndrome is a rare malformative anomaly (1/5000 women) associating uterine and vaginal aplasia with normal ovaries. We report the case of a 19-year-old woman who presented primary amenorrhea and impuberism. Hormone assay revealed hypergonadotrophic hypogonadism. The karyotype was normal, 46XX. Internal genitalia could not be identified on the pelvic ultrasound. Laparoscopy was undertaken and revealed concomitant ovarian dysgenesis and Mayer-Rokitansky-Küster-Hauser syndrome. There were no other morphological malformations. An association between these two conditions is very exceptional and appears to be coincidental, independent of chromosomal anomalies. Hormone substitution therapy remains the only therapeutic option. Hormone substitution is aimed at triggering the development of secondary sexual characters and prevent osteoporosis. There remains the unsolved problem of infertility.

[The mixed gonadal dysgenesis. Diagnostic criteria and surgical treatment]. / Criterios diagnósticos y terapéuticos de la disgenesia gonadal mixta.

The Mixed Gonadal Dysgenesis represents the 7.6% of all our patients with intersexual states. We report 14 patients who present Mixed Gonadal Dysgenesis. We have studied: diagnosis age; external genitalia description; sex assigned in birth and if has changed; the karyotype; sex chromatine; hormonal study; genitography; internal genitalia and internal Mullerians ducts structures; gonadal histologycal study; surgical treatment and hormonal treatment. The results show that 50% of the cases presents a 46XY karyotype and the other 50% mosaicisme 45XO/46XY. The histological study is very distinctive. A vulvovagynoplasty and clitoroplasty was made in all the cases. Four patients must follow an hormonal treatment after reaching puberal age. Summing up, with patients having ambiguous genitalia we can suspect it consists of a Mixed Gonadal Dysgenesis. The diagnosis must be precocious. And this diagnosis will be based in an ambiguous genitalia, with a karyotype 46XY or 45XO/46XY, the persistence of the internal Müllerian duct structures, and the histological study with a dysgenetic testis. These patients should be raised as females because they can obtain a good morphological and functional development like a normal female.

[Response of testosterone to chorionic gonadotropin stimulus in prepubertal cryptorchidism and retractile testes. Age-related changes in gonadal steroidogenesis. Authors'experience]. / La risposta del testosterone allo stimolo con gonadotropina corionica nei prepuberi criptorchidi e con testicoli retrattili. Modificazioni della steroidogenesi gonadica in rapporto all'età. Nostra esperienza.

The aim of this analysis is to evaluate the gonadal function in children with true undescended testes and in those with retractile testes, in order to verify a possible impairment of the testicular steroidogenesis due to the permanent or transitory anomalous position of the gonad outside the scrotum. The authors carried out a prospective study on 29 prepubertal children affected by true undescended testes (monolateral in 20 cases and bilateral in 9), as well as on 25 prepubertal children with retractile testes (monolateral in 10 cases and bilateral in 15), assaying the testosterone (T) levels, basal and 72 hours after stimulus with human chorionic gonadotrophin (HCG) administered in a single dose of 100 U/kg i.m. Further-more, to verify the hypothesis of a possible progressive reduction of the Leydig cells function, particularly in the gonads bilaterally affected, the authors also evaluated the testosterone response to gonadotrophic stimulus compared to age (> 0 < 4 years). This study in agreement with data already published, confirms the normality of gonadal function both in children with mono or bilateral true undescended testes and in those with retractile testes. The lower the age of the subject the higher is the peak of testosterone after stimulus, confirming the active steroidogenesis of the gonads in infants and small children and sustaining the "non quiescence" of this organ during infancy, even in cases of true undescended testes.

[The role of echography in the complex dynamic examination of patients with retardation of sexual development]. / Rol' ékhografii v kompleksnom dinamicheskom nabliudenii za bol'nymi s zaderzhkoi polovogo sozrevaniia.

Seventy-nine patients with sexual development retardation were examined, 24 of these suffered from ovarian genesis condition and 55 from central genesis condition. The findings evidence that detection of the uterus and gonads presenting as cords is one of the diagnostic criteria indicating gonadal dysgenesis. Echographic examinations carried out over the course of therapy yield a more accurate picture of ovarian function. No increase in uterine size on the echogram after discontinuation of hormonal therapy and the appearance of follicles in the ovaries after treatment point to normally functioning ovaries and helps specify the origin of sexual development retardation. In sexual development retardation of a central origin ultrasonic scanning helps assess the therapy efficacy and predict its outcome.

Depot testosterone in boys with anorchia or gonadotrophin deficiency: effect on growth rate and adult height.

Eleven teenage boys with bilateral anorchia and 12 with gonadotrophin deficiency were treated by injections of testosterone ester (enanthate) at an initial dose of 100 mg every six to eight weeks, rising to 250 mg every four weeks after three to four years. In the anorchic boys average adult height was 177.1 cm, compared with a mean mid-parental height of 174.4 cm, and mean predicted adult heights of 177.0 cm (Tanner-Whitehouse method) and 178.0 cm (Bayley-Pinneau method). In the patients with gonadotrophin deficiency, mean adult height was 176.9 cm, compared with a mean mid-parental height of 176.1 cm, and mean predicted adults heights of 174.0 cm (Tanner-Whitehouse method) and 177.3 cm (Bayley-Pinneau method). We conclude that this testosterone regimen allows achievement of full growth potential in such patients.

Multifetal pregnancy in a gonadal dysgenesis mosaic.

A successful triplet gestation in a 45,X/46,XY woman is presented. A previously hypoplastic uterus was prepared for implantation by exogenous hormone replacement. Conception was achieved through in vitro fertilization of donor oocytes and transfer of four embryos into a hormonally primed endometrium. This case illustrates that some women with 45,X/46,XY karyotype can have a successful triplet pregnancy. Therefore, a conservative approach during gonadectomy in patients with a Y chromosome may be warranted.

Hyperreninemia and hypertension observed during Kaufmann therapy of patients with gonadal dysgenesis and hypopituitarism.

Cyclic replacement therapy using estrogen and progesterone was instituted in 28 patients with gonadal dysgenesis and 13 patients with hypopituitarism. When estriol was given at a dose of 2 mg per day, 10 patients (9 gonadal dysgenesis and 1 hypopituitarism) developed hyperreninemia and 3 of the 10 patients (all gonadal dysgenesis) were associated with hypertension. These side effects subsided within 6 months when the therapy was discontinued or the dose of estriol was decreased to 1 mg per day in addition to beta-blocker. Hypercholesterolemia was observed in 8 patients, but not related to high blood pressure. Attention should be paid to plasma renin activity and blood pressure when estrogen and progesterone are given for the development of genitalia in patients with gonadal dysgenesis.

Gonadal dysgenesis: a review of 15 years' management.

Fifteen years' experience in a Menstrual Disorder Clinic revealed that gonadal dysgenesis was the commonest cause of primary amenorrhoea. Investigations using Barr Body study and laparoscopic examination were unsatisfactory and inaccurate. The invasive nature of laparoscopy was the likely principal cause for the high default rate in the early years of the Clinic. The availability of hormone radioimmunoassay and cytogenetic study has improved the diagnostic acuity. Gonadal malignancy associated with the "Y" chromosome could also be identified at its early stage. Oestrogen replacement therapy has been found to be beneficial and is associated with little side effects and no endometrial pathology has been identified.

Familial 46,XX gonadal dysgenesis.

Two sisters, ages 18 and 25, presented with primary amenorrhea and underwent clinical, hormonal, cytogenetic, and pathologic evaluation. Both were of normal stature and lacking of somatic stigmata. Both patients had normal 46,XX karyotype on peripheral blood. Streak gonads were seen in both patients and a rather scanty number of primordial follicles was found in one patient. FSH, LH, and urinary estrogens were consistent with streak gonad syndrome. Autosomal recessive inheritance has been suggested in familial aggregates with XX gonadal dysgenesis.
