This procedure which is also known as artificial insemination is often combined with hormone treatments to boost egg production can help couples with low sperm count, unexplained infertility, or cervical mucus problems. Semen is collected, and then delivered via a catheter inserted through the women's vagina and cervix to her uterus.
In vitro fertilization (IVF) refers to a procedure designed to overcome infertility and produce a pregnancy as a direct result of the intervention. In general, the ovaries are stimulated by a combination of fertility medications and then one or more oocyte(s) are aspirated from ovarian follicles. These are fertilized in the laboratory ("in vitro"), after which, one or more embryo(s) are transferred into the uterine cavity with the intent to establish a successful pregnancy.These steps occur over about a two-week interval of time, which is called an IVF cycle. IVF is a major treatment in infertility when other methods of Assisted Reproductive Technology have failed.
Intracytoplasmic sperm injection (ICSI), is an in vitro fertilization procedure in which a single sperm is injected directly into an egg and is used to overcome male infertility problems, although it may also be used where eggs cannot easily be penetrated by sperm, and occasionally in addition to sperm donation. It can be used in teratozoospermia, beside azoospermia / oligospermia; because once the egg is fertilized, abnormal sperm morphology does not appear to influence Blastocyst development or Blastocyst morphology. Even with severe teratozoospermia, microscopy can still detect the few sperm cells that have a "normal" morphology, allowing for optimal success rate.
