  1. Effects of testosterone gel followed by parenteral testosterone undecanoate on sexual dysfunction and on features of the metabolic syndrome.

    Andrologia 40(1):44 (2008) PMID 18211301

    The effects of administration of testosterone (T) gel, resulting in plasma T levels in the low range of reference values, followed by testosterone undecanoate (TU), producing plasma T levels in the mid-normal range, were measured in 27 hypogonadal men aged 47-74 years. T gel had positive effects...
  2. Distribution of N- and O-linked oligosaccharides on surface of spermatozoa from normal and infertile subjects.

    Andrologia 40(1):7 (2008) PMID 18211295

    Sperm glycocalyx modifications are very important for gamete recognition and fertilisation in mammals. These processes may be associated with specific changes in the content and distribution of surface carbohydrates. The purpose of this study was to determine the distribution of surface carbohyd...
  3. A study of the effect of straining on the cavernosus muscles: identification of 'straining-cavernosus reflex' and its clinical significance.

    Andrologia 40(1):23 (2008) PMID 18211298

    Bulbo/ischiocavernosus muscles (BCM, ICM) were found to contract on straining. We investigated the hypothesis that straining effects cavernosus muscles' contraction through a reflex action. The response of the BCM and ICM electromyographic (EMG) activity to increased intra-abdominal pressure (st...
  4. Safety and efficacy of venlafaxine in the treatment of premature ejaculation: a double-blind, placebo-controlled, fixed-dose, randomised study.

    Andrologia 40(1):49 (2008) PMID 18211302

    Venlafaxine is a serotonin-noradrenaline reuptake inhibitor antidepressant. Two hundred and twenty-two married men (mean age, 34 years) with premature ejaculation (PE) were randomly assigned to receive 75 mg of venlafaxine extended release (n = 112) (group 1) or placebo (n = 110) (group 2) for 1...
  5. Altered malondialdehyde, protein carbonyl and sialic acid levels in seminal plasma of microscopically abnormal semen.

    Andrologia 40(1):56 (2008) PMID 18211303

    Microscopically abnormal (n = 26) semen showed significantly higher levels of malondialdehyde (MDA), protein carbonyl (PC) and protein-bound sialic acid (SA) in seminal plasma as compared with normal semen (n = 24). The percentage of nonmotile spermatozoa showed significant (P < 0.01) positive c...
  6. Cryopreservation technique: comparison of Test yolk buffer versus SpermCryo and vapour versus computerised freezing.

    Andrologia 40(1):18 (2008) PMID 18211297

    Semen cryopreservation offers the possibility to maintain fertility over a long time period e.g. for male cancer patients. Although its use expands worldwide, there is no established method that can be referred to as an entrenched standard for routine laboratory use. Cryodamage is still a genera...
  7. A new experimental inbred Wistar rat varicocele model: anatomy of the left spermatic vein and the effect on histology.

    Andrologia 40(1):13 (2008) PMID 18211296

    Because of venous anatomical differences between rats and humans and the personal interpretation of these differences, there is neither consistent animal prototype nor consistent results in the study of varicocele. We established a new substrain of Wistar inbred rats, of which the left testis ve...
  8. Is erectile dysfunction a sentinel symptom for cardiovascular autonomic neuropathy in patients with type 2 diabetes?

    Andrologia 40(1):1 (2008) PMID 18211294

    The study investigated whether there is a significant association between erectile dysfunction (ED) secondary to autonomic failure, and cardiovascular autonomic neuropathy (CAN) in male patients suffering from type 2 diabetes. Twenty-two patients suffering from type 2 diabetes were recruited for...
  9. Antiapoptotic effects of dehydroepiandrosterone on testicular torsion/detorsion in rats.

    Andrologia 40(1):38 (2008) PMID 18211300

    In the present study, we aimed to evaluate the effects of dehydroepiandrosterone (DHEA) on apoptosis of testicular germ cells after repair of testicular torsion in rats. Twenty-four adult male Sprague-Dawley rats were randomly divided into four groups, with six rats in each group: sham operation...
  10. Scrotal ultrasonography: should it be used in routine evaluation of infertile men?

    Andrologia 40(1):58 (2008) PMID 18211304

    Several studies have suggested that male infertility and testicular cancer may have common aetiological factors. Scrotal ultrasonography (US) has an important role in the diagnosis of testicular tumours when not palpable by physical examination. In this study, we present two infertile men referr...
  11. Sperm protamine levels as indicators of fertilising potential in sexually mature male rats.

    Andrologia 40(1):29 (2008) PMID 18211299

    We have earlier reported that administration of cyproterone acetate, fluphenazine decanoate, tamoxifen citrate, oestradiol valerate to adult male rats, at doses of 50, 5.77, 0.71, 0.28 micromol kg(-1) body weight given for periods of 15, 60, 60, 10 days, respectively, partially suppressed/reduce...
  12. Seminal mast cells in infertile asthenozoospermic males.

    Andrologia 39(6):244 (2007) PMID 18076424

    This work aimed to assess the possible association between the presence of seminal mast cells and asthenozoospermia. One hundred and seventy-six male subjects were investigated: group (Gr)1 (n=46) normozoospermic fertile controls, Gr2 (n=62) idiopathic asthenozoospermia, Gr3 (n=32) asthenozoospe...
  13. Evaluation of antiandrogenic potentials of aqueous extract of Chromolaena odoratum (L.) K. R. leaves in male rats.

    Andrologia 39(6):235 (2007) PMID 18076423

    The antiandrogenic effect of oral administration of aqueous extract of Chromolaena odoratum leaves (250 and 500 mg kg(-1) body weight) for 14 days in male albino rats was investigated. Forty-two white albino rats were randomly divided into three groups: A, B and C. Group A which served as the co...
  14. A case report on idiopathic recurrent priapism.

    Andrologia 39(6):261 (2007) PMID 18076427

    Idiopathic recurrent priapism is a difficult problem to treat and a potentially devastating condition that may result in irreversible penile fibrosis. We present the case of a patient who, during a period of 10 years, had recurrent episodes of idiopathic priapism and we show that therapeutic opt...
  15. Secretion of testicular steroids and gonadotrophins in hypothyroidism.

    Andrologia 39(6):253 (2007) PMID 18076426

    Inconsistent alterations in gonadal steroidogenesis and pituitary functions have been reported in hypothyroid males. We have compared the lipid and endocrine profiles of the euthyroid and hypothyroid [thyroid-stimulating hormone (TSH) >100 mIU l(-1)] males. Hypothyroidism was found to be associa...
  16. Lack of association between polymorphisms in p53 gene and spermatogenetic failure in a Chinese population.

    Andrologia 39(6):223 (2007) PMID 18076421

    Although various genetic factors have been demonstrated in human male infertility, many genetic causes involving gene variants for the idiopathic male infertility have not yet been elucidated. P53 gene is involved in the meiosis of the male rat and mice, which suggested that p53 plays a critical...
  17. Psychotherapy and transsexualism.

    Andrologia 39(6):248 (2007) PMID 18076425

    We questioned whether transsexuals always require the psychotherapy demanded by the health insurance system in Germany. For this purpose, we examined 430 transsexuals who came to our facility between 1988 and 2006. At the first consultation after the history was taken, they filled out standardis...
  18. Sperm ultrastructure and meiotic segregation in an infertile 47, XYY man.

    Andrologia 39(6):229 (2007) PMID 18076422

    The majority of 47, XYY males are fertile and contribute to produce chromosomally normal children. In 47, XYY carriers, most meiotic studies indicated that the extra Y chromosomes were lost in the pre-meiotic stages, but in some cases the presence of one X and the two Y chromosomes has been dete...
  19. Influence of genital heat stress on semen quality in humans.

    Andrologia 39(6):203 (2007) PMID 18076419

    The concept that an elevation of testicular temperature results in impairment of spermatogenesis is widely accepted. Here, current knowledge concerning genital heat stress and its consequences in men is reviewed. Duration of sitting during work positively correlates with daytime scrotal temperat...
  20. Safety aspects of androgen treatment with 5alpha-dihydrotestosterone.

    Andrologia 39(6):216 (2007) PMID 18076420

    5alpha-Dihydrotestosterone (DHT), the most powerful naturally occurring androgen, is commercially available since 1982 as a gel. In view of its considerably higher biopotency (three to six times) than of testosterone, side effects, particularly on the main target organ of androgens, the prostate...
