In vitro fertilization is a fertility procedure through which egg-sperm binding occurs in the laboratory, aiming at obtaining an embryo that will be later transferred into the woman so that pregnancy occurs.
Artificial insemination is the easiest of all assisted reproductive technologies. It consists of placing those sperm presenting the highest motility rates into the woman’s cervix during her fertile days.
To set out minimum guarantees for success after an in vitro fertilisation treatment, there are a series or minimal requirements that any couple must meet. However, these requirements are not as demanding as those of artificial insemination.
Artificial insemination can be done using donor semen, in which case the results are usually better than those of artificial insemination by husband.
When egg fertilisation occurs naturally, sperm undergo this process through the female reproductive system before reaching the Fallopian tubes. Conversely, when it is performed at the laboratory, two techniques can be used: swim-up or density gradient centrifugation.
