Document Summary
Mucoproteins ejaculated sperm in the vagina during penis withdrawal) Stimulates contractions of uterine smooth muscles (to help transport sperm to site of fertilisation in oviduct) Breaks down clotted semen (to release mobile sperm within female tract) Lubricates urethra (to prevent sperm from sticking to the sides of urethra) *this is the last volume to be ejaculated. Fibrinogen (precursor of fibrin) clots semen (to help keep. Note: the ejaculated semen clots" due to the fibrinogen and lodges at the base of the cervix, so it does not drain out. Then the clot slowly melts (due to psa protease action) to release the sperm so that they can swim into the uterus. Purpose of a tight junction to act as the blood-testis barrier: The genetic modification of the diploid primary spermatocyte a haploid secondary spermatocyte will mark the changing cell as a foreign"/"non-self" cell by the host"s immune system so this barrier is needed to protect it from being destroyed.
