RESUMEN
OBJECTIVE: To evaluate the semen quality and hormonal levels in fertile men according to their level of cigarette smoking. SUBJECTS AND METHODS: We evaluated 889 fertile men who came for a vasectomy for sterilization purposes. The men included 522 non-smokers, 143 mild smokers (<10 cigarettes/day), 154 moderate smokers (11-20/day), and 70 heavy smokers (>20/day). We evaluated sperm concentration, motility, motion variables and hormonal levels in these men. RESULTS: There were no significant differences among the groups in sperm concentration or motility, or in levels of follicle-stimulating hormone, luteinizing hormone, or serum total testosterone. Also, sperm motion characteristics did not differ across the groups. Semen volume was the only semen variable which tended to decrease according to the number of cigarettes smoked. CONCLUSIONS: Cigarette smoking had no apparent effect on sperm concentration, motility or reproductive hormonal levels, but tended to reduce semen volume.

OBJECTIVE: To assess hormone levels, testicular volume, and semen characteristics of fertile men of various age groups. PATIENTS AND METHODS: The records of 889 men who sought a vasectomy between September 1999 and March 2003 were reviewed. Patients were divided into five groups by age; we evaluated semen volume, sperm concentration, motility, morphology and complex sperm motion variables. Follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone levels and both testicular volumes were compared. RESULTS: There were no differences among the groups in the levels of LH, testosterone, or right and left testicular volumes. There were differences among the five groups in FSH levels, semen volume, sperm concentration and motility. Normal morphology according to the World Health Organisation criteria was significantly lower in patients aged > 45 years. From a linear regression analysis, semen volume, sperm concentration and motility decreased by 0.01 mL, 2.1%, and 0.27%, respectively, per year, and the FSH level increased by 0.27%. CONCLUSIONS: Sperm concentration and motility decrease and FSH levels increase with age. Normal sperm morphology decreases from 45 years old. Thus, the ageing effect should be considered when proposing standard values for semen characteristics in routine semen analysis.

Media exposure regarding male sexual dysfunction and the growing number of viable treatment alternatives for erectile dysfunction has resulted in increasing numbers of men seeking clinical appointments and treatment for the condition, which has previously been considered taboo. Because these problems usually arise within the context of relationships, some investigators have alluded to increased rates of sexual dysfunction among the partners of these men. Also, since general practitioners, gynaecologists, geriatrists, and urologists are also seeing female patients for evaluation of various types of dysfunction, certain groups of these women with underlying chronic conditions have been noted to have high rates of concomitant sexual dysfunction. Physicians who have good rapport with these patients are in a privileged position to help with these intimate problems, which are often difficult for patients to discuss. Therefore, it is of extreme importance that these professionals become knowledgeable about and comfortable with the initial evaluation and possible treatment of female sexual dysfunction.

A intensa exposição pela mídia do tema disfunção sexual masculina e o número crescente de tratamentos disponíveis para a disfunção erétil têm resultado num número crescente de homens que procuram consulta e tratamento clínico para este problema, antes considerado como "tabu". Uma vez que o problema geralmente surge no contexto do relacionamento, alguns investigadores aludem às taxas crescentes de disfunção sexual nas parceiras destes homens. Além disso, clínicos, ginecologistas, geriatras e urologistas igualmente estão avaliando pacientes do sexo feminino quanto a vários tipos de disfunção. Em alguns grupos de mulheres com condições crônicas subjacentes, também têm sido observado um aumento nas taxas de disfunção sexual concomitante. Médicos que tenham estabelecido uma boa relação médico-paciente estão em posição única para ajudar com este problema, que em virtude de sua própria característica de intimidade, geralmente é de difícil abordagem para os pacientes. Desta forma, é de extrema importância que estes profissionais tenham conhecimento e sintam-se à vontade para iniciar a avaliação e possivelmente o tratamento da disfunção sexual feminina.
