Ejaculate refers to the fluid that is expelled from the male reproductive system during sexual climax, known as ejaculation. This fluid, commonly called semen, contains sperm cells, which are necessary for reproduction, as well as various other substances that help nourish and transport the sperm. The process of ejaculation typically occurs during sexual arousal and can be triggered by physical stimulation or sexual activity. The fluid is released from the penis through a series of muscular contractions, and it plays a crucial role in the reproductive process by facilitating the fertilization of an egg in females.
