First anal intercourse and condom use among men who have sex with men in Switzerland.

The aim of this study was to analyze the circumstances of first anal intercourse (FAI) among men who have sex with men (MSM) and to identify factors associated with condom use at this event. We conducted a cross-sectional survey among a convenience sample of MSM living in Switzerland (N = 2,200). Anonymous questionnaires were distributed using Swiss gay communication channels (newspapers, associations, websites) and gay bathhouses. We gathered data on age at FAI, age of the partner, degree of familiarity with him, place of first meeting, and sociodemographic indicators. We did not ask whether FAI was insertive, receptive, or both. Data were stratified by birth year classes (birth cohorts). The median age at FAI fell from 24.5 years among men born before 1965 to 20.0 years among those born between 1975 and 1984 (p < .001). In each birth cohort, between 20 and 30% reported a partner 10 years older or more. Of eight variables examined in multivariate analysis, two were positively associated with condom use: age of participants at FAI and low degree of familiarity between partners. Conversely, large age discrepancy between partners was negatively associated with condom use. In conclusion, our data showed that early initiation of anal intercourse and large age discrepancy were associated with risk taking: a pattern of initiation that may facilitate HIV transmission from older to younger cohorts of MSM. Since age at FAI is on the decrease, there is an urgent need to heighten awareness of prevention actions regarding sexual debut of MSM.

Hormonal control of spermatogenesis in men: therapeutic aspects in hypogonadotropic hypogonadism.

During the first two trimesters of intrauterine life, fetal sex steroid production is driven by maternal human chorionic gonadotropin (hCG). The HPG axis is activated around the third trimester and remains active for the first 6-months of neonatal life. This so-called mini-puberty is a developmental window that has profound effects on future potential for fertility. In early puberty, GnRH secretion is reactivated first at night and then night and day. Pulsatile GnRH stimulates both LH and FSH, which induce maturation of the seminiferous tubules and Leydig cells. Congenital hypogonadotropic hypogonadism (CHH) results from GnRH deficiency. Men with CHH lack the mini-pubertal and pubertal periods of Sertoli Cell proliferation and thus present with prepubertal testes (<4mL) and low inhibin serum levels --reflecting diminished SC numbers. To induce full maturation of the testes, GnRH-deficient patients can be treated with either pulsatile GnRH, hCG or combined gonadotropin therapy (FSH+hCG). Fertility outcomes with each of these regimens are highly variable. Recently, a randomized, open label treatment study (n=13) addressed the question of whether a sequential treatment with FSH alone prior to LH and FSH (via GnRH pump) could enhance fertility outcomes. All men receiving the sequential treatment developed sperm in the ejaculate, whereas 2/6 men in the other group remained azoospermic. A large, multicenter clinical trial is needed to definitively prove the optimal treatment approach for severe CHH.
