Human semen contains spermatozoa secreted by the testes and a mixture of components produced by the bulbo-urethral and Littre (paraurethral) glands, prostate, seminal vesicles, ampulla, and epididymis. Ejaculation is used as a synonym for the external ejection of semen, but it comprises two phases: emission and expulsion. As semen collects in the prostatic urethra, the rapid preorgasmic distension of the urethral bulb is pathognomonic of impeding orgasm, and the man experiences a sensation that ejaculation is inevitable (in women, emission is the only phase of orgasm). The semen is propelled along the penile urethra mainly by the bulbocavernosus muscle. With Kegel exercises, it is possible to train the perineal muscles. Immediately after the expulsion phase the male enters a refractory period, a recovery time during which further orgasm or ejaculation is physiologically impossible. Age affects the recovery time: as a man grows older, the refractory period increases. Sexual medicine experts consider premature ejaculation only in the case of vaginal intercourse, but vaginal orgasm has no scientific basis, so the duration of intercourse is not important for a woman's orgasm. The key to female orgasm are the female erectile organs; vaginal orgasm, G-spot, G-spot amplification, clitoral bulbs, clitoris-urethra-vaginal complex, internal clitoris and female ejaculation are terms without scientific basis. Female sexual dysfunctions are popular because they are based on something that does not exist, i.e. the vaginal orgasm. The physiology of ejaculation and orgasm is not impaired in premature ejaculation: it is not a disease, and non-coital sexual acts after male ejaculation can be used to produce orgasm in women. Teenagers and men can understand their sexual responses by masturbation and learn ejaculatory control with the stop-start method and the squeeze technique. Premature ejaculation must not be classified as a male sexual dysfunction. It has become the center of a multimillion dollar business: is premature ejaculation-and female sexual dysfunction-an illness constructed by sexual medicine experts under the influence of drug companies?
人类精液包含由睾丸分泌的精子以及由球尿道腺、利特雷（尿道旁腺）、前列腺、精囊、壶腹和附睾产生的多种成分的混合物。射精常被用作精液体外射出的同义词，但它包括两个阶段：排精和射精。当精液聚集在前列腺尿道时，尿道球在性高潮前的快速扩张是即将达到性高潮的特征，男性会有一种射精不可避免的感觉（在女性中，排精是性高潮的唯一阶段）。精液主要通过球海绵体肌沿阴茎尿道推进。通过凯格尔运动，可以训练会阴肌肉。在射精阶段之后，男性立即进入不应期，这是一段恢复时间，在此期间生理上无法再次达到性高潮或射精。年龄会影响恢复时间：随着男性年龄增长，不应期会延长。性医学专家仅在阴道性交的情况下考虑早泄，但阴道性高潮并无科学依据，所以性交持续时间对女性性高潮并不重要。女性性高潮的关键在于女性的勃起器官；阴道性高潮、G点、G点增强、阴蒂球、阴蒂 - 尿道 - 阴道复合体、阴蒂内体和女性射精等术语都没有科学依据。女性性功能障碍很常见，因为它们基于不存在的东西，即阴道性高潮。早泄时射精和性高潮的生理功能并未受损：它不是一种疾病，男性射精后的非性交性行为可用于使女性达到性高潮。青少年和男性可以通过自慰了解自己的性反应，并通过停 - 动法和挤压技术学习射精控制。早泄不应被归类为男性性功能障碍。它已成为一项价值数百万美元业务的核心：早泄以及女性性功能障碍是性医学专家在制药公司影响下虚构出来的疾病吗？
