    Prospective study of histological and endocrine parameters of gonadal function in boys with cryptorchidism.
    J Pediatr Urol 2016 Aug 27;12(4):238.e1-6. Epub 2016 May 27.
    Institute for Cryptorchidism Research, Kindermedizinisches Zentrum, Liestal, Switzerland.
    Introduction: A transient increase in gonadotropins and testosterone during mini-puberty causes gonocytes to differentiate into Ad spermatogonia, which establish male germ cell memory and male-specific DNA methylation pathways. Over half of patients with unilateral cryptorchidism and the majority of patients with bilateral cryptorchidism display an abnormal spermiogram, which indicates that unilateral cryptorchidism is a bilateral disease; therefore, it represents a serious andrological problem. The aim of this study was to evaluate relationships between hormonal parameters and testicular biopsy findings in boys with cryptorchidism. Read More

    Division of Urology, Department of Surgery, University of Utah Health Care, 30 N 1900 E, Rm 3B420, Salt Lake City, UT, 84132, USA.
    Subfertility is defined as the condition of being less than normally fertile though still capable of effecting fertilization. When these subfertile couples seek assistance for conception, a thorough evaluation of male endocrine function is often overlooked. Spermatogenesis is a complex process where even subtle alterations in this process can lead to subfertility or infertility. Read More

    Double separate versus contiguous pituitary adenomas: MRI features and endocrinological follow up.
    Pituitary 2016 Oct;19(5):472-81
    Department of Pathology, Anschutz Medical Campus, University of Colorado at Denver, 12605 E. 16th Avenue, Aurora, CO, 80045, USA.
    Purpose: Double pituitary adenomas are defined as two adenomas within a gland. These have distinct light microscopic and immunohistochemical features and may be clearly-separate or contiguous. Most reports have focused on the various hormonal combinations in double tumors rather than on any potential increased risk for residual mass or endocrinopathy. Read More

    The Study of Gonadal Hormonal Abnormalities and Sexual Dysfunction in HIV Positive Females: An Exploratory Study.

    Introduction: Every endocrine gland has been reported to be affected at varying rates in HIV. HIV is a highly stigmatized chronic disease with a substantial co-occurrence of mental and sexual health problems; however the sexual health problems in women have not been extensively studied.

    Aim: To study the gonadal hormonal abnormalities and sexual dysfunction in HIV positive female patients and its possible association. Read More

    Human chorionic gonadotropin stimulation gives evidence of differences in testicular steroidogenesis in Klinefelter syndrome, as assessed by liquid chromatography-tandem mass spectrometry.
    Eur J Endocrinol 2016 Jun;174(6):801-11
    Unit of EndocrinologyDepartment of Biomedical, Metabolic and Neural Sciences, University of Modena and Reggio Emilia, Modena, Italy Department of MedicineEndocrinology, Metabolism and Geriatrics, Azienda USL of Modena, Modena, Italy Center for Genomic ResearchUniversity of Modena and Reggio Emilia, Modena, Italy.
    Background: Men with Klinefelter syndrome (KS) show hypergonadotropic hypogonadism, but the pathogenesis of hypotestosteronemia remains unclear. Testicular steroidogenesis in KS men was evaluated over three decades ago after human chorionic gonadotropin (hCG) stimulation, but inconclusive results were obtained. Intriguingly, some recent studies show increased intratesticular testosterone concentrations in men with KS. Read More
