Artificial insemination by donor is an assisted reproduction technique that is recommended for women that don’t have a male partner, be it the case of women that opt for forming a family on their own or lesbian couples that choose insemination as reproductive technique.

Another alternative, in which the sperm of the donor is used, is for heterosexual couples, when any of the following circumstances applies:

  • Absence of spermatozoa in the ejaculated sample, alteration named azoospermia.
  • Low spermatic quality that could compromise the formation and development of the embryo.
  • Possibility of infection of sexually transmitted diseases to the woman and the baby, as long as other techniques, such as sperm washing, cannot be applied.
  • Avoiding the transmission of genetic alterations in which the pre-implantation diagnosis cannot be used.

The doctor of the clinic must evaluate the situation of every patient and recommend one technique or another. However, some requisites must be fulfilled, in order for the woman or couple to be able to have access to this technique.

Requisites for the woman

In the case of women, the requisites are the same as for an artificial insemination:

  • Tubal permeability, at least in one of the Fallopian tubes.
  • Good ovarian response and capability to ovulate.
  • A prepared endometrium with the right thickness to receive the foetus.

Requisites for the donor

In this case, we refer to the requisites that the donor must meet:

  • A total motile spermatozoa count superior to 5 million spermatozoa/ml in his defrosted and capacitated sperm.
  • Satisfactory pass the health tests needed, in order to become a donor.
  • There mustn’t have been more than six children born out of the donor’s sperm, as the law establishes.
  • The donation must be completely anonymous, according to the Spanish law BOE n. 282, 22 November 1988.
