BACKGROUND: Compared to adult studies, studies which involve the treatment of pediatric congenital hypogonadotropic hypogonadism (CHH) are limited and no universal treatment regimen is available. The aim of this study was to evaluate the feasibility of human chorionic gonadotropin (hCG)/human menopausal gonadotropin (hMG) therapy for treating male adolescents with CHH. METHODS: Male adolescent CHH patients were treated with hCG/hMG (n = 20) or a gonadotropin-releasing hormone (GnRH) pump (n = 21). The treatment was divided into a study phase (0-3 months) and a follow-up phase (3-12 months). The testicular volume (TV), penile length (PL), penis diameter (PD), and sex hormone levels were compared between the two groups. The TV and other indicators between the groups were analyzed using a t-test (equal variance) or a rank sum test (unequal variance). RESULTS: Before treatment, there was no statistical difference between the two groups in terms of the biochemistry, hormones, and other demographic indicators. After 3 months of treatment, the TV of the hCG/hMG and GnRH groups increased to 5.1 ± 2.3 mL and 4.1 ± 1.8 mL, respectively; however, the difference was not statistically significant (P > 0.05, t = 1.394). The PL reached 6.9 ± 1.8 cm and 5.1 ± 1.6 cm (P < 0.05, t = 3.083), the PD reached 2.4 ± 0.5 cm and 2.0 ± 0.6 cm (P < 0.05, t = 2.224), respectively, in the two groups. At the end of 6 months of treatment, biomarkers were in normal range in the two groups. Compared with the GnRH group, the testosterone (T) level and growth of PL and PD were significantly greater in the hCG/hMG group (all P < 0.05). While the TV of both groups increased, the difference was not statistically significant (P > 0.05, t = 0.314). After 9 to 12 months of treatment, the T level was higher in the hCG/hMG group. Other parameters did not exhibit a statistical difference. CONCLUSIONS: The hCG/hMG regimen is feasible and effective for treating male adolescents with CHH. The initial 3 months of treatment may be a window to optimally observe the strongest effects of therapy. Furthermore, results from the extended time-period showed positive outcomes at the 1-year mark; however, the long-term effectiveness, strengths, and weaknesses of the hCG/hMG regimen require further research.

Gonadotropin therapy is commonly used to induce virilization and spermatogenesis in male isolated hypogonadotropic hypogonadism (IHH) patients. In clinical practice, 5.6%-15.0% of male IHH patients show poor responses to gonadotropin treatment; therefore, testosterone (T) supplementation can serve as an alternative therapy to normalize serum T levels and promote virilization. However, treatment with exogenous T impairs spermatogenesis and suppresses intratesticular T levels. This retrospective study aimed to determine whether oral testosterone undecanoate (TU) supplementation together with human chorionic gonadotropin (hCG) would negatively affect spermatogenesis in IHH patients compared with hCG alone. One hundred and seven IHH patients were included in our study. Fifty-four patients received intramuscular hCG and oral TU, and 53 patients received intramuscular hCG alone. The median follow-up time was 29 (range: 12-72) months in both groups. Compared with the hCG group, the hCG/TU group required a shorter median time to normalize serum T levels (P < 0.001) and achieve Tanner stage (III and V) of pubic hair and genital development (P < 0.05). However, there were no significant differences in the rate of seminal spermatozoa appearance, sperm concentration, or median time to achieve different sperm concentration thresholds between the groups. In addition, there were no significant differences in side effects, such as acne and gynecomastia, observed in both groups. This study indicates that oral TU supplementation together with hCG does not impair spermatogenesis in treated IHH patients compared with hCG alone, and it shortens the time to normalize serum T levels and promote virilization.

Hypogonadotropic hypogonadism (HH) is a rare disease in which medical treatment has a high success rate to achieve fertility. This study aimed to analyze the efficacy of hormone replacement therapy and determine predictive factors for successful spermatogenesis and spontaneous pregnancy in patients with idiopathic HH. A total of 112 patients with low testosterone (T), luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and normal prolactin levels were diagnosed with HH and administered LH and FSH analogs as hormone replacement therapy. During treatment, 96 (85.7%) patients had sperm present in ejaculate samples. Among these patients, 72 were married and wanted a child. Of these 72 patients, 48 (66.7%) of couples had pregnancies from natural conception. After initiation of treatment, the mean time for the appearance of sperm in semen was 9.48 months. There were no significant differences between baseline FSH, T, and LH levels; however, older age, larger testicular size, and low rate of undescended testes were favorable factors for successful spermatogenesis. Larger testicular size and older age were also the main predictive factors for natural conception. We found that patients with undescended testes had a younger age, smaller testes, and lower T levels compared with patients exhibiting descended testes. The rate of sperm found in the ejaculate was not significantly decreased in patients with undescended compared with descended testis (73.7% vs 87.6%, P = 0.261). The medical approach for males with HH and azoospermia provides a successful treatment modality in regard to successful spermatogenesis and achievement of pregnancy.

A variety of methods for testosterone replacement therapy (TRT) exist, and the major potential risks of TRT have been well established. The risk of developing polycythemia secondary to exogenous testosterone (T) has been reported to range from 0.4% to 40%. Implantable T pellets have been used since 1972, and secondary polycythemia has been reported to be as low as 0.4% with this administration modality. However, our experience has suggested a higher rate. We conducted an institutional review board-approved, single-institution, retrospective chart review (2009-2013) to determine the rate of secondary polycythemia in 228 men treated with subcutaneously implanted testosterone pellets. Kaplan-Meyer failure curves were used to estimate time until the development of polycythemia (hematocrit >50%). The mean number of pellets administered was 12 (range: 6-16). The mean follow-up was 566 days. The median time to development of polycythemia whereby 50% of patients developed polycythemia was 50 months. The estimated rate of polycythemia at 6 months was 10.4%, 12 months was 17.3%, and 24 months was 30.2%. We concluded that the incidence of secondary polycythemia while on T pellet therapy may be higher than previously established.

Objective: To evaluate the effects of Testosterone Undecanoate Pills (TUP) on insulin resistance (IR) in type-2 diabetes men with hypogonadism. METHODS: We randomly divided 82 type-2 diabetes patients with hypogonadism into a treatment (n = 42) and a control group (n = 40), both maintaining their glucose- and lipid-reducing therapies, while the former treated orally with TUP in addition. After 6 months of medication, we compared the body mass index (BMI), waist circumference (WC), blood glucose level, HbA1c, lipid profile, IR index obtained by homeostatic model assessment (HOMA-IR), insulin sensitivity index (ISI), sex hormone levels, and sexual function scores between the two groups of patients. RESULTS: Compared with the baseline, the patients in the treatment group showed significant decreases after medication in BMI (［26.71 ± 2.39］ vs ［25.15 ± 2.28］ kg/m2, P <0.05), WC (［89.96 ± 9.13］ vs ［85.03 ± 9.58］ cm, P <0.05), HbA1C (［7.73 ± 1.31］ vs ［7.01 ± 1.25］ %, P <0.05), and triglyeride (［1.97 ± 0.83］ vs ［1.41 ± 0.69］ mmol/L, P <0.05), a markedly elevated level of total testosterone (［7.16 ± 2.21］ vs ［14.22 ± 2.63］ nmol/L, P <0.05), and remarkable improvement in HOMA-IR (3.76 ± 1.18 vs 2.55 ± 1.03, P <0.05), ISI (96 ± 51 vs 138 ± 53, P <0.05) and total scores of the Aging Males' Symptoms (P <0.05). But no significant changes were observed in the scores of the International Index of Erectile Function (IIEF) after treatment (13.28 ± 6.38 vs 14.95 ± 6.08, P >0.05). CONCLUSIONS TUP can significantly improve insulin resistance in type-2 diabetes men with hypogonadism.

Objective: To investigate the clinical effects of oral Testosterone Undecanoate Capsules (TUC) combined with Qilin Pills (QLP) on late-onset hypogonadism (LOH) in men. METHODS: Sixty-three LOH patients meeting the inclusion criteria were randomly divided into a control group (aged ［48.4 ± 6.2］ yr, n = 32) and an experimental group (aged ［47.2 ± 5.6］ yr, n = 31) to be treated with oral TUC (80 mg, qd) and TUC + QLP (6g, tid), respectively, both for 3 months. Comparisons were made between the two groups of patients in the IIEF-5 scores, total testosterone (TT) levels, and scores in the Aging Males' Symptoms (AMS) scale before and after treatment. RESULTS: After treatment, the patients of the experimental group, as compared with the controls, showed a significantly increased IIEF-5 score (21.7 ± 5.8 vs 15.9 ± 4.7, P <0.05) and TT level (［16.7 ± 2.2］ vs ［13.1 ± 2.8］ nmol/L, P <0.05), but a decreased AMS score (20.7 ± 5.7 vs 31.3±6.5, P <0.05). CONCLUSIONS TUC combined with Qilin Pills has a better effect and a lower rate of adverse reactions than TUC used alone in the treatment of late-onset hypogonadism in males.

As more and more studies suggest that type 2 diabetes mellitus (T2DM) is closely related to male hypogonadism, people begin to pay more attention to the role of testosterone in the development of T2DM and the effect and safety of testosterone supplementary therapy. There is some controversy in randomized controlled studies and meta-analyses about the effects of testosterone supplementation on the blood glucose level, androgen deficiency symptoms, and cardiovascular diseases. This review focuses on the diagnosis of hypogonadism in T2DM males, differences in the therapeutic effects and safety of testosterone replacement among different studies, and rational use of testosterone supplementation for T2DM patients.
