It is usually a white or yellowish, sticky substance made up of sperm male cells for sexual reproduction floating in a fluid called seminal plasma that has water and different chemicals in it. Normally, an ejaculation makes between 1. Some scientists think that semen that is taken into a woman's body causes her not to feel depressed or sad. On the other hand, if semen touches another person's body, it can pass on sexually transmitted infections STIs. In a few cases, it can also make the other person's immune system weaker, or cause the person to have an allergic reaction. The risks of these health problems happening can be reduced if the man wears a condom when having sex.
Pre-ejaculate also known as pre-ejaculatory fluid , pre-seminal fluid or Cowper's fluid , and colloquially as pre-cum is a clear, colorless, viscous fluid that is emitted from the urethra of the penis during sexual arousal. It is similar in composition to semen but has distinct chemical differences. The presence of sperm in the fluid is variable from low to absent. Pre-ejaculate functions as a lubricant and an acid neutralizer. The fluid is discharged from the urethra of the penis during arousal , masturbation , foreplay or at an early stage during sexual intercourse , some time before the individual fully reaches orgasm and semen is ejaculated. It is primarily produced by the bulbourethral glands Cowper's glands , with the glands of Littre the mucus-secreting urethral glands also contributing. Pre-ejaculate contains some chemicals associated with semen, such as acid phosphatase.
Semen quality is a measure of male fertility , a measure of the ability of sperm in semen to accomplish fertilization. Semen quality involves both sperm quantity and quality. Cryptorchidism , hypospadias , testicular cancer and poor semen quality make up the syndrome known as testicular dysgenesis syndrome.
Semen , also known as seminal fluid , is an organic fluid that may contain spermatozoa. It is secreted by the gonads sexual glands and other sexual organs of male or hermaphroditic animals and can fertilize female ova. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or "swim". Semen is produced and originates from the seminal vesicle , which is located in the pelvis.
