PREPARATION STEPS FOR ARTIFICIAL INSEMINATION. A woman needing artificial insemination to achieve pregnancy can obtain a sperm sample from her male partner or sperm from sperm donation may be used. Donated sperms are used if the womans partner produces too few motile sperm, or if he carries a genetic disorder, or if the woman has no male partner. Sperm is usually obtained through masturbation or the use of an electrical stimulator, although a special condom , known as a collection condom, may be used to collect the semen during intercourse. Sperm provided by a sperm bank will always be produced by a donor attending at the sperm banks premises in order to ascertain the donors identity on every occasion. The donor masturbates to provide an ejaculate in a small container. The contents of the container are usually extended with chemicals in order to provide a number of vials for insemination. The sperm is frozen and quarantined for a period of usually six months and the donor re-tested prior to the sperm being used for artificial insemination. A sperm donor is usually advised not to ejaculate for two to three days before providing the sample, to increase the sperm count. A womans menstrual cycle is closely observed, by tracking body temperature and changes in vaginal mucus, or using ovulation kits, ultrasounds or blood tests. When using intrauterine insemination (IUI), the sperm must have been “ washed ” in a laboratory and concentrated. The process of “washing” the sperm increases the chances of fertilization and removes any mucus and non- motile sperm in the semen. Pre and post concentration of motile sperm is counted.
