To understand how your daily life affects your sperm, you first need to know how healthy sperm is made.<\/p>\n

Sperm Production in Numbers<\/h2>\n

A healthy man produces around 100 million sperm cells each day, but only a few will ever reach and fertilize an egg.<\/p>\n

Unlike women, who are born with all the eggs they will ever have\u2014around 400 mature eggs over a lifetime\u2014men make sperm continuously. Throughout life, they produce billions. This process happens in the seminiferous tubules inside the testes, as shown in Figure 1.<\/p>\n

Fig 1:<\/strong>
\n\"Sperm
\nThe testes contain many thin, coiled tubes called seminiferous tubules. Inside these tubes, sperm cells form and grow. The Sertoli cells<\/strong> in the walls support and feed the developing sperm by providing nutrients and blood products.<\/p>\n

Once sperm cells reach maturity, they move to the epididymis<\/strong> and then into the ductus deferens<\/strong> for short-term storage. There, they gain the ability to move and swim properly.<\/p>\n

The Production of Sperm Cells (Spermatogenesis)<\/h2>\n

Sperm production<\/a>, known as spermatogenesis<\/em>, is a complex and carefully controlled process. It usually takes about 64 days<\/strong>\u2014sometimes as few as 42 or as many as 76 days\u2014to complete [1]<\/a>.<\/p>\n

Hormones such as FSH<\/strong>, LH<\/strong>, and testosterone<\/strong> start and control sperm production. During this process, immature cells divide and change into fully formed sperm that can swim and fertilize an egg.<\/p>\n

The hypothalamus<\/strong>, a small gland in the brain, controls these hormones. Figure 2 shows spermiogenesis<\/strong>\u2014the final phase of sperm development\u2014where spermatids become fully mature, motile sperm cells.<\/p>\n

Fig 2:<\/strong>

\nThe figure shows spermiogenesis, the last stage of sperm formation. Here, an immature spermatid gradually transforms into a sperm cell (steps 1\u20137).<\/p>\n

Sperm production depends on healthy conditions inside the body. When a man is sexually aroused, the mature sperm mixes with seminal fluid<\/a>\u2014a white liquid from the seminal vesicles, bulbourethral glands, and prostate. Together, sperm and fluid form semen<\/strong>.<\/p>\n

As seen in Figure 1, sperm are created inside the seminiferous tubules and then move to the epididymis<\/strong>, where they continue to mature and develop motility.<\/p>\n

Advice from Dr. Fatin Willendrup<\/a>, ExSeed Head of Medical Affairs<\/h2>\n

\u201cLifestyle, health issues, and ejaculation frequency all influence sperm quality. If you\u2019re worried about your fertility, don\u2019t wait\u2014speak with your doctor or take an at-home sperm test.\u201d<\/p><\/blockquote>\n

What Can Affect Healthy Sperm?<\/h2>\n

A healthy, mature sperm cell looks like the one shown in Figure 3.<\/p>\n
