How often is semen produced

How can the amount of ejaculate be increased?

When the man orgasm, ejaculation usually also occurs. The amount of ejaculate can vary from person to person. The amount of sperm decreases somewhat with age and can only be increased to a limited extent with the help of various measures.

What is ejaculate and what is it made of?

Ejaculate (semen) refers to the seminal fluid that emerges from the urethra during an ejaculation. It consists of:

  • Sperm (seminal threads, spermatozoa)
  • Glandular secretions (mainly from the prostate and seminal vesicles).

How much ejaculate is normal?

The amount of ejaculate in a healthy, sexually mature man is between 1.5 and 6 ml, with men around the age of 30 producing the most on average. With increasing age, the amount of ejaculate slowly decreases again. The following applies: From the volume of the ejaculate, neither the fertility nor the degree of arousal can be inferred.

Possible causes for a lower amount of ejaculate

  • Frequency of ejaculation
  • other underlying disease
  • mental health
  • Taking medication
  • Disruption of the hormonal control circuits between the brain and testicles, hormonal disorders
  • Ejaculation disorders such as retrograde ejaculation

How is semen produced?

The production of sperm in the testes is a complex process in which various hormone-producing and regulating glands are involved. Most of the seminal fluid is produced in the prostate and the so-called seminal vesicles. Sperm production is controlled by the pituitary gland (pituitary gland): It releases the two hormones FSH and LH, which in turn have a direct effect on the formation of new sperm (FSH) in the testes and ensure testosterone production in the testes (LH). The sperm is stored in the epididymis and spermatic ducts. During orgasm, the prostate and vas deferens contract strongly, causing ejaculation.

How quickly do sperm renew themselves?

A healthy man produces new sperm every day, so there are always sperm cells of varying degrees of maturity in the testicles and seminal canals. The process until the sperm mature takes about 72 days. If there is no ejaculation for a long time, unused sperm are broken down by the body itself or in an involuntary ejaculation (pollution) - often during sleep - rejected.

Why does semen production decrease with age?

In men, too, the hormonal balance changes over the course of life, but not as much as in women. With increasing age, the testosterone production slowly decreases again, but only to a small extent, so that the fertility in men - despite the lower amount of ejaculate - is usually maintained into old age.

A mostly benign enlargement of the prostate (prostatic hyperplasia), which occurs frequently in old age, can also be the cause of a reduced amount of ejaculate: The swelling of the prostate inside can obstruct the excretory ducts, which means that less ejaculate is released during orgasm.

How can the sperm production or the amount of ejaculate be increased?

Since both sperm production and the amount of ejaculate are primarily controlled by hormones, these processes can only be influenced "from outside" to a limited extent. In any case, a healthy lifestyle helps to maintain virility into old age.

These include:

  • Avoidance of direct heat effects on the testicles (sauna, hot baths, heated seats in the car)
  • Avoid tight pants
  • drink enough
  • balanced diet rich in vitamins
  • Use of vegetable oils
  • Sufficient exercise
  • Pelvic floor training
  • Refrain from nicotine and alcohol
  • Avoiding stress

Are there any drugs to stimulate semen production?

Medicines to increase semen production may only be taken in consultation with the attending physician and prior detailed examination.
