    Reproduction is the process by which organisms make more organisms like themselves. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. In the human reproductive process, two kinds of sex cells, or gametes GAH-meetz , are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes meets an egg, this fertilized egg is called a zygote ZYE-goat.

    Azoospermia (No Sperm Count): Types, Causes, Tests & Treatments

    Azoospermia leads to male infertility. During ejaculation, sperm move from the testes and the epididymis into the vas deferens. Tightening contraction of the vas deferens moves the sperm along. Secretions from the seminal vesicle are added and the seminal fluid continues to move forward toward the urethra. Before reaching the urethra, the seminal fluid passes by the prostate gland, which adds a milky fluid to the sperm to form semen. Lastly, the semen is ejaculated released through the penis through the urethra. If you have azoospermia, you have no measurable sperm in your ejaculate.

    Male Reproductive System

    The world's oldest new dad, who, at the reported age of 96, just fathered a baby boy in India, says he's done having kids. But if he wanted to break his record again in a couple years, would biology allow it? Though sperm production does usually keep up until a man's dying day, it's a misconception that "biological clocks" are only of concern to women. The effects of aging on fertility have been studied far less in men than in women, but research shows that both volume and quality of semen generally fall off as a man gets older. A study published in the American Journal of Obstetrics and Gynecology found that, among a sample of couples using in vitro fertilization, every additional year of a man's age corresponded to an percent increase in the odds that a couple would not achieve a pregnancy.

    Nearly 1 in 7 couples is infertile, which means they haven't been able to conceive a child even though they've had frequent, unprotected sexual intercourse for a year or longer. In up to half of these couples, male infertility plays at least a partial role. Male infertility can be caused by low sperm production, abnormal sperm function or blockages that prevent the delivery of sperm.
