根据刊发在FASEB时代周刊上的一项新深入研究，也可能对年长者乳腺造成了化学物质依赖性。

一项本意在于降低年长者早产的深入研究挖掘出一种叫做CB2的伦受体与乳腺生成的更大幅度有关。深入研究职员解读说，这一挖掘出表明，可能会破坏年长者的早产。

由博洛尼亚耶鲁大学Paola Grimaldi他组织的深入研究开发团队让实验激伦服药不同的药物，其中一组服药CB2受体的活化剂，另一组则服药CB2受体肽，第三组作为对照组只服药生理盐水。深入研究表明，服药CB2活化剂的激伦有更迟的生精相对速度，而服药CB2肽的激伦则显示了相反的优点并有较慢的乳腺造成了率。这些表明，CB2的酪氨酸需要保持稳定一定的平衡状态以保证正确的乳腺造成了更大幅度。

FASEB时代周刊的主笔Thoru Pederson指出，这项深入研究有可能为年长者不育症的治疗法开辟新深入研究方向。他还说：“内源性伦对乳腺正常造成了会有正面优点，如果采用可以大幅度激发这种优点的-HT，有可能发展出治疗法年长者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“.
