英语百科
Sexual maturity 性成熟Sexual maturity is the age or stage when an organism can reproduce. It is sometimes considered synonymous with adulthood. In humans, the process of sexually maturing is termed puberty. Most multicellular organisms are unable to sexually reproduce at birth (or germination), and depending on the species, it may be days, weeks, or years until their bodies are able to do so. Also, certain cues may cause the organism to become sexually mature. They may be external, such as drought, or internal, such as percentage of body fat (such internal cues are not to be confused with hormones which directly produce sexual maturity). |
