Sex-Specific Effects of Gender Identification on Pain Study Recruitment

Epidemiological, clinical, and laboratory studies show sex differences in pain responses, with women more sensitive to nociceptive stimulation and more vulnerable to long-term pain conditions than men. Because of evidence that men are culturally reinforced for the ability to endure (or under-report) pain, some of these findings might be explained by sociocultural beliefs about gender-appropriate behavior. One potential manifestation of these effects might be differential participation in pain studies, with men adhering to stereotypical masculine roles viewing participation as a way to demonstrate their masculinity. To test this possibility, we assessed gender identification in 137 healthy participants. At the end of the assessment, they were asked if they would like to participate in other research studies. Interested participants were then asked to participate in a study involving administration of pain-evoking stimulation. We compared individuals who agreed to participate in the pain study with those who declined. We observed a significant Sex × Participation interaction in masculine gender identification, such that men (but not women) who agreed to participate identified significantly more with masculine gender. Among masculine gender traits examined, we found that high levels of aggression and competitiveness were the strongest predictors of pain study participation. Our results suggest that men in pain studies might have higher levels of masculine gender identification than the wider male population. Taken together with previous findings of lower levels of pain sensitivity (or reporting) in masculine-identifying male participants, these results suggest an explanation for some of the sex-related differences observed in pain responses.

沙眼衣原体感染与血清中抗精子抗体相互关系的研究

目的 探讨男性不育患者CT感染与血清中AsAb的关系。方法 应用聚合酶链反应(PCR)与ELISA法对177例男性不育患者分别进行CT和AsAb检测。结果 CT阳性者AsAb的阳性率(27.9％)明显高于CT阴性者的AsAb阳性率(8.3％,X2=12.2,P<0.01)。结论 沙眼衣原体感染可增加AsAb的产生,可能与男性不育有关。     

Girly mags and girly jobs: Pornography and gendered inequality in forensic practice

This article presents findings from a discourse analytic study into the constructive nature and textual variations of language in a high‐security hospital. It explores how mental health nurses, and men convicted of sexual offences who also have a diagnosis of personality disorder, talked about pornography and sexual crime in the context of forensic provision. Access to sexually‐explicit media, in relation to treatment environments for people convicted of sexual offences, has become a cause for professional and political concern in the UK. Data collection and analysis, undertaken concurrently, were informed by a discursive design. Semistructured interviews, as co‐constructed accounts with nursing staff and detained patients, were audio‐taped and transcribed. Data were coded to identify the discursive repertoires, or collective talk, of respondents. In contrast to empirical inquiry into pornography and sexual violence, methodology shifted attention from measurement to meaning, and situated research in a clinical domain. The findings focus on performative language use, where talk about pornography textured the treatment environment, contributed to an overtly masculine discourse, framed the ward as male space, and promoted gendered inequality. The discussion questions the legitimacy of the therapeutic enterprise.     

男性不育患者精浆NO水平及其与抗精子抗体的关系

目的 :观察男性不育患者精浆中 NO水平变化及其与 As Ab的关系。方法 :采用EL ISA法测定了 1 1 6例男性不育患者及 49例正常生育男性血清和精浆 As Ab,同时采用硝酸还原酶法测定 1 1 6例男性不育患者与 49例正常生育男性精浆中 NO水平。结果 :男性不育患者 As Ab阳性率 3 8.8% ,显著高于正常生育组 4.0 8% ( P<0 .0 1 )。不育组精浆中 NO水平 1 4 2 .8± 3 9.2 μmol/ L,显著高于正常生育组 83 .9± 2 6 .1 μmol/ L( P<0 .0 1 )。As Ab阳性的不育患者 NO水平 1 59.3± 42 .6μmol/ L ,显著高于 As Ab阴性组 1 3 4 .2±3 1 .4μmol/ L ( P<0 .0 1 )。结论 :As Ab与男性不育有着密切相关性 ,且为重要的免疫因素 ,男性不育患者精浆内高水平的 NO与 As Ab的产生可能有着密切的关系。     

中药乳宁冲剂对实验性兔乳腺组织增生的影响

中药乳宁冲剂能调摄冲任、疏肝活血，对异常雌、孕激素刺激造成的兔乳腺组织增生有明显的抑制作用。异常雌性激素的刺激可能主要通过雌激素受体（ER）及孕激素受体（PR）的介导引起兔乳腺组织增生，而乳宁冲剂对实验性兔乳腺组织增生的抑制作用可能是通过降低乳腺组织ER、PR含量．使乳腺组织对雌性激素的敏感性下降而实现的。     

Nutrition et infertilité masculine : revue de la littérature

Infertility affects about 15% of couples. Many foctors relating to lifestyle and environment (drugs, alcohol, tobacco, pollution, exposure to heat, diet and sport…) are likely to influence fertility. As an adapted nutrition could prevent 30% of cancers, diet could be essential, but largely neglected, in the prevention of infertility. Some studies tried to explore the impact of diet on testis function and on semen quality, unfortunately rarely informative. Similarly, supplementation with vitamins or micronutrients, prescribed in order to improve sperm parameters, have rarely been validated by double-blind, randomized, placebo controlled studies. The aim of this review is to assess the role of nutrition in spermatogenesis and sperm maturation.
