For men with normal sperm counts, studies find that semen volume and sperm count/concentration increase after two days of abstinence.
The next time you have sex, the number of sperms is not as much as the first time, but the quality of sperm remains stable, and that quantity is enough for fertilization to occur. This proves that having sex twice in a row is still possible to get pregnant if there is no reasonable protection.
How long does it take for sperm to refill? Men produce sperm every day. By the end of a complete sperm production cycle, men can regenerate approximately eight billion sperms. However, an entire sperm regeneration cycle takes around 2.5 months.
Some studies suggest that moderate ejaculation (2–4 times per week) is associated with a lower prostate cancer risk. However, ejaculating more often doesn't mean your cancer risk drops even more.
According to some studies, 18-year-old males have a refractory period of about 15 minutes, while those in their 70s take about 20 hours, with the average for all men being approximately half an hour. Although rarer, some males exhibit no refractory period or a refractory period lasting less than 10 seconds.
The “pooled” samples significantly increased the total sperm count, potentially increasing the chance of pregnancy. Another small study in 2016 had similar results, concluding that, for men with low sperm count, ejaculating twice in one hour produced more normal sperm and better motility in the second ejaculation.
Samples collected between the hours of 5am and 7.30am were found to display a statistically higher sperm concentration, total sperm count and a greater percentage of normally shaped sperm, when compared with samples that were collected later in the day.
It takes just one sperm to fertilize a woman's egg. Keep in mind, though, for each sperm that reaches the egg, there are millions that don't. On average, each time men ejaculate they release nearly 100 million sperm.

Ejaculating is a natural bodily function that can bring pleasure and release tension. Ejaculating daily is unlikely to cause any harm to men who are in good overall health, but excessive ejaculation can lead to temporary fatigue or discomfort in the genital area and may affect sperm count over time.
If sperm does not travel out by ejaculation, the body breaks down semen and reabsorbs it. It may also release the sperm during nocturnal emission, also known as a wet dream. If people have had a vasectomy, their sperm remains inside the body and does not mix into the semen.
While there is no definite age at which male ejaculation ceases, it has been suggested that it may happen when a man reaches his late 40s or early 50s. It is important to note, however, that this is not a universal rule and some men may continue to ejaculate at a later age.
Age. As men get older, some find they take longer to get an erection, and erections are longer to maintain. Conversely, younger men might ejaculate sooner than they'd like (although that can happen at any age).
Certain factors, however, can contribute to a reduction in male ejaculate, including your age, particular medications, or even a surgical procedure you've had. Experts note that low testosterone levels, which affect about 5 million American men, can also result in the release of less semen during ejaculation.
Semen can become watery or thinner than usual if someone masturbates or engages in sexual activity multiple times each day. In this case, abstaining from sexual activity for a few days may help treat the issue. Watery semen can sometimes indicate that a person has a low sperm count or reduced semen quality.
A man might have watery semen if he doesn't get enough zinc in his diet. Zinc is an important nutrient for sperm production. Men who ejaculate several times a day might also develop watery semen, since the body needs time to “catch up” on its semen production.
A male's body is constantly creating sperm, but sperm regeneration is not immediate. On average, it takes a male around 74 days to produce new sperm from start to finish. Although the average time is 74 days , the actual time frame for an individual to make sperm can vary.
Most research suggests that frequent ejaculation offers several health benefits. There is no evidence that regular ejaculation causes any health issues. More frequent ejaculation may mean a man gains more health benefits. The positive benefits of ejaculation do not mean that all men must ejaculate frequently.
A trained expert checks your sperm count, their shape, movement, and other characteristics. In general, if you have a higher number of normal-shaped sperm, it means you have higher fertility. But there are plenty of exceptions to this. A lot of guys with low sperm counts or abnormal semen are still fertile.
A woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.
Scientists discovered that there was pretty much no difference in the odds of getting pregnant between the group that got up and moved around and the one that went on short bed rest.
The concentration of sperm is what makes the semen cloudy and thick, so if your ejaculate is watery it is possible that you have a low sperm count. This doesn't mean you're infertile (so precautions to prevent pregnancy still need to be taken for couples that don't want to get pregnant).
Elevated prolactin levels post-ejaculation could play a role in your inability to get it up again. “Increased prolactin and subsequent lower testosterone is like a double whammy affecting your sex,” says Dr Brahmbhatt. By contrast, women generally have a much shorter refractory period – or even none at all.
