The term used to describe unexplained infertility.
The embedding of the fertilized egg in the endometrium of the uterus.
A procedure in which several eggs are retrieved from the ovary, fertilized in the laboratory with sperm from the male partner, and a small selection of the resulting embryos are then transferred to the uterus for transplantation.
The inability to conceive after repeated intercourse without contraception for one year.
A micromanipulation procedure where a single sperm is injected into an egg to enable fertilization. This procedure is used in cases where the male partner has very low sperm counts, non-motile sperm, poor sperm morphology (shape) or is unable to ejaculate and therefore cannot either have intercourse or produce a semen sample.
