ARTIFACT (ARTEFACT)

Written by

A foreign body found in living tissue viewed under a microscope. It is usually caused by faulty preparation of a specimen, with the result that disease or abnormality seems to be present.

Artificial Insemination

In this method of fertilisation, SEMEN is collected either by the husband (AIH) or by a donor (AID) through masturbation and introduced into the cervix (neck of the womb) by means of an instrument around the time of OVULATION.

AIH is thought to be particularly useful for men with retrograde ejaculation or erectile IMPOTENCE. AID may be considered when the partner’s sperm count is either very low or zero.

Insemination can be made with fresh or frozen semen. Donors should be tested for sexually transmitted diseases and their identity remain unknown to the infertile couple. The pregnancy rate over six months is 50–60 per cent. Artificial insemination is usually done at specially staffed centres with facilities to store semen and provide the individuals involved with appropriate counselling. Success rates are up to 70 per cent with fresh semen (used over a six-month period) and over 50 per cent with frozen semen.
