摘要引言动物界的生殖器形态（特别是雄性）具有广泛的差异，即使是具有相似一般形态的密切相关物种的成员也可能具有显着不同的生殖器。目的介绍性医学专家对生殖器进化假说的基本认识，重点是性选择理论。方法对生殖进化理论的相关文献进行综述。主要结果测量分析支持生殖器进化的性选择理论的证据。结果提出了几种解释生殖器进化的理论。目前，性选择理论被认为是解释生殖器进化的有效和可靠的证据。然而，包括性冲突在内的其他理论仍在调查中。所有的生殖器进化理论都有自己的弱点和优点。鉴于许多复杂的生物学机制，大多数未知的，涉及在生殖器的进化过程中，因此，它是合理的结论，没有一个理论可以独立地解释生殖器的进化。这些机制很可能证明具有协同效应，而不是排他性效应。Shamloul R，El-Sakka A和Bella AJ。性选择和生殖器进化：概述。
ABSTRACT Introduction Genital morphology (especially male) among the animal kingdom is characterized by extensive differences that even members of closely related species with similar general morphology may have remarkably diverse genitalia. Aim To present the sexual medicine specialist with a basic understanding of the current hypotheses on genital evolution with an emphasis on the sexual selection theories. Methods A review of current literature on the theories of genital evolution. Main Outcome Measures Analysis of the supporting evidence for the sexual selection theories of genital evolution. Results Several theories have been proposed to explain genital evolution. Currently, the sexual selection theories are being considered to present valid and solid evidence explaining genital evolution. However, other theories, including sexual conflict, are still being investigated. All theories of genital evolution have their own weaknesses and strengths. Conclusions Given that many complex biological mechanisms, mostly unknown yet, are involved in the process of genital evolution, it is thus reasonable to conclude that not one theory can independently explain genital evolution. It is likely that these mechanisms may prove to have synergistic rather than exclusive effects. Shamloul R, El-Sakka A, and Bella AJ. Sexual selection and genital evolution: An overview.
