Understanding the Male Reproductive System
男性生殖系统概述
The male reproductive system is responsible for producing sperm and is essential for reproduction. Let's take a closer look at its structure and function.
男性生殖系统负责产生精子，对生殖至关重要。我们来详细地看一下它的结构和功能。
The main organs of the male reproductive system are located in the pelvis area. They include the testes, sperm ducts (vas deferens), penis, and three glands: the seminal vesicle, prostate gland, and bulbourethral gland.
男性生殖系统的主要器官位于骨盆区域。它们包括睾丸、精子管（输精管）、阴茎和三个腺体：精囊、前列腺和尿道球腺。
The testes are located in a sac-like structure called the scrotum, which hangs between the thighs. The testes produce sperm, which are male sex cells.
睾丸位于悬挂在大腿之间的称为阴囊的囊状结构中。睾丸产生男性性细胞--精子。
Each sperm has a head, middle piece, and tail. The sperm travel through the vas deferens to the seminal vesicle and prostate gland, where they are mixed with fluids to form semen. The semen then passes through the urethra and exits the body through the penis.
每个精子都有头部、中间部分以及尾部。精子通过输精管，到达精囊和前列腺，然后与液体混合形成精液。随后，精液经过尿道，通过阴茎排出体外。
The penis is made of spongy tissue and has two parts: the shaft and the glans tip. The urethra runs through the penis, allowing both semen and urine to exit the body.
阴茎由海绵状组织组成，分为两个部分：阴茎轴和龟头。尿道穿过阴茎，使得精液和尿液都能排出体外。
The testes also produce testosterone, a hormone responsible for developing secondary sexual characteristics such as a deep voice, muscle development, and facial hair during puberty.
睾丸也会产生睾酮，睾酮是负责青春期第二性特征发育，如声音低沉、肌肉发育和胡须生长的激素。
