Semen quality is a measure of the ability of semen to accomplish fertilization. Thus, it is a measure of fertility in a man. It is the sperm in the semen that is of importance. Semen quality involves both sperm quantity and quality. Decreased semen quality is a major factor of male infertility. Cryptorchidism , hypospadias , testicular cancer and poor semen quality make up the syndrome known as testicular dysgenesis syndrome.

You produce sperm every day, but a full sperm regeneration cycle spermatogenesis takes about 64 days. Spermatogenesis is the complete cycle of sperm production and maturation. Read on to learn more about how often your body replenishes your sperm, what happens in your body to make sperm production possible, how you can help keep your sperm healthy, and more. Your testicles are constantly producing new sperm in spermatogenesis.
Sperm are constantly in danger. Once mature, sperm are stored in a long tube called the epididymis where they wait to be ejaculated. Vaginal walls tend to be acidic to protect women from potential infections.
The aim of the study was to assess the effect of four repeated ejaculations on the same day at two-hour intervals on conventional and functional semen parameters. Furthermore, intracellular reactive oxygen ROS production, sperm DNA fragmentation and mitochondrial function were evaluated by flow cytometry. An overall decreasing trend was noted in the conventional semen parameters at second, third and fourth evaluations after two hours of abstinence in comparison to first evaluation after 3—4 days of abstinence. The findings of the present study indicate the potential use of additional semen samples with repeated ejaculations at short abstinence times in assisted reproduction procedures particularly from severe oligospermic men.
