Semen cell formation

The sperm cells (synonymously are the concepts sperm cells and spermatozoen also used for this) are produced in a complex gait system. The sperm cells permanently must be produced newly in the seminiferous tubules. With the women the ovums (approx. 400 000) are already available against this at the birth. (Infections, environmental pollutants, medicines), is therefore understandable, this the quality of the sperm varies and is dependent on external influences.

The seminiferous tubules are lined by different cells laminatedly. Within around three months the on the outside lying cells walk to the middle of the seminiferous tubule. At this walk it comes to the reduction division (meiosis) and to the form change of the spermiums. The originally round cells stretch and one recognizes a head (contains the genetic information), a middle piece (engine) as well as a long tail. One considers it is understandably the education period of three months why the sperm is examined in longer temporal distances, for example at a child wish medical treatment. The spermatozoen permanently copied immigrate into, now a gait system this directly lifts testicles and this is called epididymis. The spermiums ripen and are stored at this two to four meters reach for gait. The largest portion of the spermiums which are into the epididymis is out skidded at the ejaculation (ejaculation) about the spermatic duct, the prostate and the urethra within very short time. This process doesn't always take place equally well. Variations in this one in the set of the ejaculate as well as in the number of spermiums are therefore normal.

However, not only this is gait system in the testicle for the formation of spermiums but the so-called Leydig cells also are between these gaits. The male hormone testosterone is formed in them. The deep voice and also the semen cell production is responsibly for the muscle growth, the male body hairiness. The system of the hormone producing cells isn't as delicate as the semen cell production (spermatogenense). Normal testosterone values are often found at men with a reduced spermium production. The libido and power of a man often say nothing about its procreative capacity.

In the semen cell production the pituitary hormones play FSH and LH an important role. While they are causing the follicular maturation and the ovulation with the woman, they are responsible for the semen cell formation at the man. FSH stimulates directly the seminiferous tubules, LH causes the formation of testosterone.
