RESUMO

Currently, most men with infertility cannot be given an aetiology, which reflects a lack of knowledge around gamete production and how it is affected by genetics and the environment. A failure to recognize the burden of male infertility and its potential as a biomarker for systemic illness exists. The absence of such knowledge results in patients generally being treated as a uniform group, for whom the strategy is to bypass the causality using medically assisted reproduction (MAR) techniques. In doing so, opportunities to prevent co-morbidity are missed and the burden of MAR is shifted to the woman. To advance understanding of men's reproductive health, longitudinal and multi-national centres for data and sample collection are essential. Such programmes must enable an integrated view of the consequences of genetics, epigenetics and environmental factors on fertility and offspring health. Definition and possible amelioration of the consequences of MAR for conceived children are needed. Inherent in this statement is the necessity to promote fertility restoration and/or use the least invasive MAR strategy available. To achieve this aim, protocols must be rigorously tested and the move towards personalized medicine encouraged. Equally, education of the public, governments and clinicians on the frequency and consequences of infertility is needed. Health options, including male contraceptives, must be expanded, and the opportunities encompassed in such investment understood. The pressing questions related to male reproductive health, spanning the spectrum of andrology are identified in the Expert Recommendation.

RESUMO

The use of donor sperm is increasing, yet limited information is available about the health and development of children conceived from donor sperm. This retrospective descriptive study aimed to assess health and development in a cohort of school-aged children who were conceived using donor sperm. Participants included 224 children, aged 5-11 years, who were conceived using donor sperm. Participants' mothers completed a questionnaire comprising validated scales examining their child's current and past physical, psychosocial and mental health, healthcare needs and child development, as well as the mothers' health and wellbeing. At the conclusion of the study, the response rate was 296 out of 407 (72.7%), with a participation rate of 224 out o 407 (55.0%). Compared with the normative Australian population, sperm donor-conceived children had similar physical, psychosocial and mental health and development. A modest increase in healthcare needs was evident. The study concludes that in school-aged children conceived using donor sperm, most aspects of child health and wellbeing are similar to the general population.

RESUMO

INTRODUCTION: This article, Part 1 of the Endocrine Society of Australia's position statement on male hypogonadism, focuses on assessment of male hypogonadism, including the indications for testosterone therapy. (Part 2 will deal with treatment and therapeutic considerations.) MAIN RECOMMENDATIONS: Key points and recommendations are:Pathological hypogonadism arises due to diseases of the hypothalamus or pituitary gland (hypogonadotropic hypogonadism) or testes (hypergonadotropic hypogonadism). It is a clinical diagnosis with a pathological basis, confirmed by hormone assays.Hormonal assessment is based on measurement of circulating testosterone, luteinising hormone (LH) and follicle-stimulating hormone (FSH) concentrations. Measurement of sex hormone-binding globulin levels can be informative, but use of calculated free testosterone is not recommended for clinical decision making.Testosterone replacement therapy is warranted in men with pathological hypogonadism, regardless of age.Currently, there are limited data from high-quality randomised controlled trials with clinically meaningful outcomes to justify testosterone treatment in older men, usually with chronic disease, who have low circulating testosterone levels but without hypothalamic, pituitary or testicular disease.Obesity, metabolic syndrome and type 2 diabetes are associated with lowering of circulating testosterone level, but without elevation of LH and FSH levels. Whether these are non-specific consequences of non-reproductive disorders or a correctable deficiency state is unknown, but clear evidence for efficacy and safety of testosterone therapy in this setting is lacking.Glucocorticoid and opioid use is associated with possibly reversible reductions in circulating testosterone level, without elevation of LH and FSH levels. Where continuation of glucocorticoid or opioid therapy is necessary, review by an endocrinologist may be warranted.Changes in management as result of the position statement: Men with pathological hypogonadism should be identified and considered for testosterone therapy, while further research is needed to clarify whether there is a role for testosterone in these other settings.

RESUMO

PURPOSE: There is considerable information regarding the medical and cognitive aspects of Klinefelter syndrome yet little research regarding its psychosocial impact. This study investigates the personal impact of Klinefelter syndrome and the influence of age at diagnosis, clinical, social, and demographic factors on adult quality of life outcomes. METHODS: Men from across Australia, diagnosed with KS at different ages, were recruited through multiple sources. Participants completed a questionnaire assessing subjective well-being, body image, self-esteem, mental health, social support, and general health. RESULTS: Eighty-seven individuals self-completed the questionnaire. All outcomes were much poorer for the study population than for the general male population. Individuals diagnosed later in life reported many of the same symptoms as those diagnosed at younger ages. Employment status, social support, and phenotypic features were the strongest predictors of psychosocial outcomes. Age at diagnosis was not as influential because it did not correlate with phenotypic severity score. CONCLUSION: This is the first quantitative study to show Klinefelter syndrome has a significant personal impact. Men diagnosed with Klinefelter syndrome later in life reported similar difficulties as those at younger ages, suggesting that they would benefit from early detection and intervention. Understanding factors influencing this can assist in providing adequate services to individuals with Klinefelter syndrome, their partners, families, and the health professionals caring for them.

RESUMO

CONTEXT: Male hormonal contraceptive methods require effective suppression of sperm output. OBJECTIVE: The objective of the study was to define the covariables that influence the rate and extent of suppression of spermatogenesis to a level shown in previous World Health Organization-sponsored studies to be sufficient for contraceptive purposes (< or =1 million/ml). DESIGN: This was an integrated analysis of all published male hormonal contraceptive studies of at least 3 months' treatment duration. SETTING: Deidentified individual subject data were provided by investigators of 30 studies published between 1990 and 2006. PARTICIPANTS: A total of 1756 healthy men (by physical, blood, and semen exam) aged 18-51 yr of predominantly Caucasian (two thirds) or Asian (one third) descent were studied. This represents about 85% of all the published data. INTERVENTION(S): Men were treated with different preparations of testosterone, with or without various progestins. MAIN OUTCOME MEASURE: Semen analysis was the main measure. RESULTS: Progestin coadministration increased both the rate and extent of suppression. Caucasian men suppressed sperm output faster initially but ultimately to a less complete extent than did non-Caucasians. Younger age and lower initial blood testosterone or sperm concentration were also associated with faster suppression, but the independent effect sizes for age and baseline testicular function were relatively small. CONCLUSION: Male hormonal contraceptives can be practically applied to a wide range of men but require coadministration of an androgen with a second agent (i.e. progestin) for earlier and more complete suppression of sperm output. Whereas considerable progress has been made toward defining clinically effective combinations, further optimization of androgen-progestin treatment regimens is still required.
