Could doctors at fertility clinics be giving men bad advice? Da Li and Dr. Recent research from Li's and Wang's lab, published in the journal Molecular and Cellular Proteomics, upends conventional wisdom that abstaining between efforts to conceive can improve a couple's chances of success. The research team worked with almost couples to test whether how long a couple waits between efforts to conceive could change their success rates. Some earlier studies had shown that semen produced shortly after a man's most recent ejaculation -- within three hours or so -- had faster and more motile sperm than if the man abstained for several days before ejaculating again.
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. The full process takes about 64 days. During spermatogenesis, your testicles make several million sperm per day — about 1, per second. By the end of a full sperm production cycle, you can regenerate up to 8 billion sperm.
Several factors have been shown to influence semen parameters, one of which is sexual abstinence; a clinical criteria included in the semen evaluation to provide maximum sperm quality. The aim of the present study was to assess the effect of a daily ejaculation frequency on conventional and functional semen parameters. Semen samples were collected daily over a period of two weeks of which every second sample per person was processed and analyzed according to the World Health Organization guidelines. Furthermore, mitochondrial function, intracellular reactive oxygen species production and sperm DNA fragmentation were evaluated by flow cytometry. Total sperm count and seminal volume per ejaculation declined and remained decreased for the duration of the daily ejaculation period.
