One-sixth of Swiss children are affected by overweight, and despite the implementation of an evidence-based multiprofessional approach, there has only been moderate therapeutic success. An unfavourable home environment and psychosocial stresses on the family may impede lifestyle changes. This longitudinal observational study included children with obesity (body mass index [BMI] ≥97th percentile [P.]) or overweight (BMI ≥ 90th P.) with a comorbidity, and who were participating in a regional 12-month multiprofessional group programme (MGP). Two health professionals routinely visited the family home at baseline (T0) to identify obesogenic environmental factors and psychosocial stress using an observation and question checklist and the Heidelberger stress scale (HSS). At T0 and after an 8-month intensive intervention phase (T1), the BMI standard deviation score (BMI-SDS) and its associations with the environmental and psychosocial factors were assessed. Twenty-eight children (17 male) met the criteria for participation in the MGP. At T0, age was 11.2 ± 1.71 years, BMI 28.1 ± 4.7 kg/m 2 and BMI-SDS 2.9 ± 0.8, means ±SD. By T1, the mean BMI-SDS had decreased significantly, by -0.11 (p < .05). The stress scores (30.46 ± 17.8) were elevated and the subcategories of financial and social stress showed a trend towards predicting BMI or BMI-SDS at T0 and T1, but none of the other supposed obesogenic risk factors significantly predicted weight status. Conducting home visits allowed health professionals to identify obesity-promoting home conditions and, more importantly, otherwise undisclosed high psychosocial stress and resource limitations in families that impacted the children's obesity before and after the MGP intervention., (© 2023 The Authors.

Objective: To investigate the suitability of intramuscular testosterone undecanoate (TU) injections for substitution therapy in hypogonadal men., Study Design: Clinical, open-label, non-randomized trial of 13 hypogonadal men receiving 4 intramuscular injections of 1000 mg TU in 4-ml castor oil at 6-week intervals. General wellbeing, sexual parameters, clinical chemistry, hormone levels, prostate size and prostate-specific antigen (PSA) were evaluated over 24 weeks and compared with baseline values., Results: Testosterone serum levels were never found below the lower limit of normal and only briefly after the 3rd and 4th injection above the upper limit of normal, while peak and trough values increased over the 24-week observation period. Oestradiol and dihydrotestosterone followed this pattern, not exceeding the normal limits. No serious side-effects were noted. Slight increases in body weight, haemoglobin, haematocrit, prostate volume and PSA, suppression of gonadotrophins as well as increased ejaculation frequency occurred as signs of adequate testosterone substitution., Conclusion: Testosterone undecanoate is well tolerated by the patients. The injection intervals can be extended even beyond the 6-week periods chosen in the present study. Altogether, intramuscular testosterone undecanoate appears to be well suited for long-term substitution therapy in hypogonadism and hormonal male contraception.

Approaches to hormonal male contraception are predominantly based on injectable testosterone (T) application. As most users would prefer an injection-independent modality, this study was designed to develop a self-applicable hormonal male contraceptive regimen by combining transdermal T with an oral gestagen. Eleven healthy men (23-40 yr old) were treated with oral levonorgestrel and transdermal T for 24 weeks. T was applied daily as a transdermal patch to be worn on the trunk. Levonorgestrel was taken orally at a dose of 250 microg daily up to week 12, followed by 500 microg to week 24 in those volunteers who had not become azoospermic by that time. Within 24 weeks, 2 of 11 volunteers had become azoospermic, and 3 of 11 showed sperm concentrations below 3 million/mL. The sperm concentrations of the remaining volunteers declined, but failed to reach the limit considered compatible with contraception by WHO. Treatment resulted in suppression of LH, FSH, and sex hormone-binding globulin, whereby the volunteers with lower sperm concentrations showed more pronounced suppression than the others. Mean T concentrations remained within the lower limit of normal and on occasions were below this level. There were no complaints of hypoandrogenism. Although mean levels of low density lipoprotein cholesterol, apolipoprotein B, as well as basal and postprandial insulin increased, high density lipoprotein cholesterol and apolipoprotein A-I decreased during the treatment phase. Changes in lipid parameters were normalized within 3 weeks after cessation of medication. Although only 5 of 11 volunteers reached the target sperm counts (<3 million/mL), the study shows that a self-applicable hormonal male contraceptive could be developed.

Stimulatory therapy with either GnRH or gonadotropins is an effective treatment to induce spermatogenesis and achieve paternity in men with secondary hypogonadism. However, there is still uncertainty about the optimal treatment modality and schedule, the duration of treatment necessary and the influence of interfering factors such as maldescended testes. We have extended our previous series of men treated for secondary hypogonadism and now present our therapeutic experience with 42 cases. Twenty-one patients with hypothalamic disorders (11 with idiopathic hypogonadotropic hypogonadism (IHH) and 10 with Kallmann syndrome (KalS)) were treated with GnRH (group Ia) or human chorionic gonadotropin (hCG)/human menopausal gonadotropin (hMG) (group Ib), and 21 patients with hypopituitarism (group II) were treated with hCG/hMG. A total of 5 7 treatment courses were initiated for induction of spermatogenesis, 36 of these for the purpose of induction of pregnancy in the female partner. Bilateral testicular volumes doubled within 5-12 months of therapy. Spermatogenesis as evidenced by the appearance of sperm in the ejaculate was induced in 54/57 courses. Pregnancies occurred in 26/36 courses. Unilaterally maldescended testes did not preclude patients with IHH or KalS from gaining fertility under therapy and spermatogenesis could be successfully initiated even in some individuals with bilateral maldescended testes. In general there was a tendency for a longer duration of therapy until induction of spermatogenesis in patients with a history of bilateral cryptorchidism. However, this did not reach statistical significance. In patients with IHH or KalS treated with either hCG/hMG or GnRH there were no statistically significant differences in terms of duration to appearance of sperm or pregnancy rates. Even in KalS patients as old as 43 years spermatogenesis could be induced. In repeatedly treated patients stimulation of spermatogenesis tended to be faster while time until induction of pregnancy was significantly shorter in the second treatment course. In conclusion, GnRH or hCG/hMG are effective therapeutic modalities for patients with IHH or KalS. It remains to be determined whether highly purified urinary gonadotropin preparations or recombinant LH and FSH will provide therapeutic advantages.
