男性不育可以简单的分为精子产生障碍（睾丸衰竭）与精子运输障碍（梗阻性）。在所有由于梗阻性因素引起的男性不育，以及很大一部分由于精子生成障碍引起的男性不育病例中都需要手术干预。本文将介绍的手术方案包括精索静脉曲张手术、精道梗阻重建术以及用于辅助生育技术的取精子术。在大多数可适用的情况下，我们使用药物治疗作为提高生育率的最初选择，或者作为提高取精子成功率的辅助方法。在过去的10-15年里，治疗男性不育的技术发展迅速，现在大部分病例都可以成功治愈。我们可以纠正由于精索静脉曲张引起的精子生成障碍，可以解决梗阻性无精子症，也可以通过取精子术结合体外受精技术治疗无精子症。

Euro Pacific Capital首席执行官Peter ***撰文表示,美国不应继续量化宽松政策(QE),因为经济对于刺激政策的依赖就像吸毒者深陷毒品,这种依赖只会进一步加深;如果选择QE3,下一次复苏将需要更大规模的刺激来实现。他认为美国需要的是将劳动力和资本从服务业转向产品生产的重新配置,这虽然会带来短期镇痛,但却是可行的办法。

We use particle-in-cell,fully electromagnetic,plasma kinetic simulation to study the effect of external magnetic field on electron scale Kelvin–Helmholtz instability(ESKHI).The results are applicable to collisionless plasmas when,e.g.,solar wind interacts with planetary magnetospheres or a magnetic field is generated in AGN *** find that as in the case of magnetohydrodynamic(MHd)KHI,in the kinetic regime,the presence of an external magnetic field reduces the growth rate of the *** the MHd case,there is a known threshold magnetic field for KHI stabilization,while for ESKHI this is to be analytically *** a kinetic analytical expression,we use several numerical simulation runs to establish an empirical dependence of ESKHI growth rate,Γ(B_(0))ω_(pe),on the strength of the applied external magnetic *** find the best fit is hyperbolic,Γ(B_(0))ω_(pe)=Γ_(0)ω_(pe)/(A+BB_(0)),where Γ_(0) is the ESKHI growth rate without an external magnetic field and B_(0)=B_(0)/B_(MHd)is the ratio of external and two-fluid MHd stability threshold magnetic field,derived *** analytical theory to back up this growth rate dependence on the external magnetic field is *** results suggest that in astrophysical settings where a strong magnetic field pre-exists,the generation of an additional magnetic field by the ESKHI is suppressed,which implies that nature provides a“safety valve”—natural protection not to“over-generate”magnetic field by the ESKHI ***,we find that our two-fluid MHd threshold magnetic field is the same(up to a factor √γ_(0))as the dC saturation magnetic field,previously predicted by fully kinetic theory.
