根据刊登在FASEB杂志上的一项新科学研究，也可能对男同性恋体外造成了有害抑制作用。

一项本意在于进一步提高男同性恋生育能力的科学研究挖掘出一种被称作CB2的素介导与体外生成的更实质性有关。科学研究医护人员理解知道，这一挖掘出暗示，可能则会破坏男同性恋的生育能力。

由意大利罗马大学Paola Grimaldi领导成员的科学研究一个团队让测试动物模型过量不同的药物，其中举例来说过量CB2介导的活化剂，另举例来说则过量CB2介导衍生物，第一组作为对照组只过量生理盐水。科学研究结果暗示，过量CB2活化剂的动物模型有更快的生精流速，而过量CB2衍生物的动物模型则标示出了相反的优点并有更慢的体外造成了率。这些结果暗示，CB2的激活必需维持一定的恒定以尽可能适当的体外造成了更实质性。

FASEB杂志的主编Thoru Pederson提到，这项科学研究有可能为男同性恋不育症的治疗新建新的科学研究方向。他还知道：“内源性素对体外正常造成了则会有正面优点，如果采用可以实质性激发这种优点的激动剂，有可能发展出治疗男同性恋不育症的一些新疗法”。

Marijuana Can Affect Male Fertility, Suggests New Study

The study focusing mainly on finding ways to enhance male fertility has found that a ‘marijuana receptor’ called CB2 (a cannabinoid receptor) is linked with the regulation of sperm production (a process named spermatogenesis). This might sound like good news, but the researchers of the study explain that this finding indicates that marijuana might thus be disrupting male fertility.

Led by Paola Grimaldi from the University of Rome Tor Vergata, Italy, the team treated mice with different agents: one group, with an activator of the CB2 receptor; another with an inhibitor of the same receptor; a third group acting as the control one received only a saline solution.

The findings show that the CB2 activator group had a more rapid rate of spermatogenesis while the inhibitor group displayed the opposite effect as they had a slower rate of sperm production. These results suggest that CB2 activation is needed to be in a certain balance for spermatogenesis to occur properly and adequately.

This research might be opening up new doors for the treatment of male infertility, as pointed out by the Editor-in-Chief of The FASEB Journal, Thoru Pederson. According to the latter, “the normal beneficial effects of endogenous cannabinoids on spermatogenesis can be stimulated further by a chemical mimic, an agonist, is a potentially promising new idea for treating male infertility“.
