We detected lower frequency of cryptorchidism at birth in Lithuanian boys than in Danes (9.0%), but higher than in Finns (2.4%). We had expected the frequencies in Lithuania and Finland to be relatively similar because the other symptoms of TDS (incidence of testicular cancer and semen quality) are close in these countries.

The study aimed to analyse emotional state, quality of life and cognitive functions in young hypogonadal men. Thirty-four males with hypogonadism (age 29.1 ± 10.5 years) and 34 age-matched healthy males (age 30.5 ± 11.0 years) were recruited. Their emotional state was evaluated by Profile of Mood States, quality of life - by WHO Brief Quality of Life Questionnaire - and cognitive functioning - by Trail Making Test and Digit Span Test of Wechsler Adult Intelligence Scale. It was found that young men with hypogonadism had higher depression-dejection (13.1 ± 8.8 versus 7.4 ± 5.9, P = 0.003), fatigue-inertia (10.0 ± 5.8 versus 7.0 ± 4.9, P = 0.030), confusion-bewilderment (5.1 ± 4.6 versus 2.3 ± 3.1, P = 0.004) and lower vigour-activity (14.3 ± 5.1 versus 17.7 ± 4.3, P = 0.008) levels than age- and sex-matched controls. Quality of life psychological (13.1 ± 2.8 versus 15.1 ± 1.9, P = 0.005) and social (13.6 ± 2.4 versus 15.7 ± 2.0, P < 0.001) domains were significantly worse in men with hypogonadism than in controls. Cognitive functions were significantly worse (P < 0.001) in men with hypogonadism than in controls, showing worse executive function, attention, visual scanning abilities and psychomotor speed. A significant correlation was found between testosterone concentration and quality of life psychological domain. Cognitive functioning scores were significantly related with FT4 concentration. It is concluded that young hypogonadal patients have impaired emotional state and quality of life, but the most severe impairment was found in cognitive functioning.

The aim of the study was to examine the effects of two-year testosterone replacement therapy on cognitive functioning, emotional state and quality of life in young and middle-aged men with hypogonadotropic hypogonadism. Nineteen males diagnosed with hypogonadotropic hypogonadism participated in the study. Cognitive functions were assessed by Trail Making Test and Digit Span Test of Wechsler Adult Intelligence Scale. Emotional state was evaluated by Profile of Mood States. Quality of life was evaluated by WHO Brief Quality of Life Questionnaire. Changes after two-year testosterone replacement therapy were detected in Trail Making A (42.9 ± 22.3 vs. 36.2 ± 22.5, p = .050) and B (90.6 ± 55.3 vs. 65.6 ± 21.4, p = .025) tests, showing improvement in attention and visual scanning abilities, executive function and psychomotor speed, as well as in Digit Span Test forward score (5.4 ± 2.0 vs. 6.1 ± 2.6, p = .046), showing improvement in attention capacity and psychomotor speed. No significant differences were observed in emotional state and quality of life. In conclusion, beneficial effect in cognitive functioning (improved attention and visual scanning ability, executive function and psychomotor speed), but not in emotional state and quality of life, was observed in young and middle-aged hypogonadal men after two-year testosterone replacement therapy.

Objective: To establish whether diabetic ketoacidosis (DKA) or HbA1c at onset is associated with year-three HbA1c in children with type 1 diabetes (T1D).Methods: Children with T1D from the SWEET registry, diagnosed <18 years, with documented clinical presentation, HbA1c at onset and follow-up were included. Participants were categorized according to T1D onset: (a) DKA (DKA with coma, DKA without coma, no DKA); (b) HbA1c at onset (low [<10%], medium [10 to <12%],
