Posted by Liza Roscetti Meyer on October 11, Your partner has been instructed it is time for her IUI and you are on deck to produce a sample. How dirty are they? It simply means that we are separating the good sperm from the seminal fluid. Seminal fluid needs to be removed prior to IUI because 1 it contains debris, white blood cells and dead sperm cells, which can produce oxygen radicals that can impair fertilization of the egg.

Sperm is the male reproductive cell. In the types of sexual reproduction known as anisogamy and its subtype oogamy , there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. A uniflagellar sperm cell that is motile is referred to as a spermatozoon , whereas a non-motile sperm cell is referred to as a spermatium. Sperm cells cannot divide and have a limited life span, but after fusion with egg cells during fertilization, a new organism begins developing, starting as a totipotent zygote.

Male and female reproductive traits display some of the most rapid evolution observed in nature and it has been suggested that sexual conflict is a major driver of this diversity. Other evolutionary conflicts are also known to propel evolutionary change, such as host—parasite and predator—prey conflicts. However, these conflicts are thought to have little role in shaping male and female reproductive traits. Although some researchers have focused on these other selective pressures to explain reproductive diversity, no attempt has been made to quantify the relative significance of the different mechanisms in shaping reproductive traits. The evolutionary quickie Dr Otti has previously attempted to explain the phenomenon of post-ejaculatory variation in reproductive success in terms of the relative contributions of natural and sexual selection.
