A 1992 World Health Organization report described normal human semen as having a volume of 2 mL or greater, pH of 7.2 to 8.0, sperm concentration of 20×10 6 spermatozoa/mL or more, sperm count of 40×10 6 spermatozoa per ejaculate or more, and motility of 50% or more with forward progression (categories a and b) of 25% or more with rapid ...
The average volume of semen produced at ejaculation is 2 to 5 millilitres (about a teaspoon), [7] containing an average of 182 million sperm. [4] Only a small proportion of the sperm in each ejaculation reach the site of fertilization in the fallopian tubes, their numbers decreasing exponentially as they progress through the female reproductive ...
Human sexual reproduction, to produce offspring, begins with fertilization. Successful reproduction typically involves sexual intercourse between a healthy, sexually mature and fertile male and female. [1] During sexual intercourse, sperm cells are ejaculated into the vagina through the penis, resulting in fertilization of an ovum to form a ...
Female sperm can refer to either: A sperm which contains an X chromosome, produced in the usual way in the testicles, referring to the occurrence of such a sperm fertilizing an egg and giving birth to a female. [1] A sperm which artificially contains genetic material from a female. [2]
They are homologous to Bartholin's glands in females. The bulbourethral glands are responsible for producing a pre-ejaculate fluid called Cowper's fluid (known colloquially as pre-cum ), which is secreted during sexual arousal, neutralizing the acidity of the urethra in preparation for the passage of sperm cells.

Sperm storage organs in the fruit fly Drosophila melanogaster.Female was first mated with GFP-male and then re-mated with RFP-male. Female sperm storage is a biological process and often a type of sexual selection in which sperm cells transferred to a female during mating are temporarily retained within a specific part of the reproductive tract before the oocyte, or egg, is fertilized.
Dog sperm collection. In order to collect semen from a male dog, an artificial vagina is prepared, [15] [16] which is a conical thin latex sleeve ending in a sterile collection tube. The inside of the latex sleeve is lightly lubricated. [17] The male is allowed to sniff a female in estrus. Experienced studs cooperate readily in the process.
This engorgement of blood vessels increases the volume of transudate from the vaginal walls. [4] Transudate has a neutral pH, so increases in its production can temporarily shift vaginal pH to be more neutral. [4] Semen has a basic pH and can neutralize the acidity of the vagina for up to 8 hrs. [4]
