Artificial insemination

December 2016
Artificial insemination is one of the techniques used in assisted reproductive technology, or ART. This field intervenes in the lives of certain couples, when they are not able to initiate pregnancy. After performing various exams to research the cause of this infertility, the technique of artificial insemination may be chosen. After sperm is collected through a natural release from the testicles of the male partner, puncturing his testicles, or through a donor, this semen is deposited in the uterine cavity of the woman. This technique is principally advised for moderate troubles of the man's spermatozoons, problems of the woman's cervical phlegm preventing the migration of spermatozoons, or in the case of male sterility, in which case there is recourse to a sperm donor. It is also the first technique tried in case of inexplicable infertility that lasts more than two years.



Definition

Artificial insemination is a method which involves manually selecting good quality sperm in a laboratory to be introduced into a woman at time of ovulation. .

It is useful if:
  • there are problems with ovulation
  • there are male factors such as impotence or premature ejaculation
  • no cause can be found for infertility
  • if there is oligospermia (sperm concentration is below normal)
  • if donor sperm is being used
  • Insemination is usually carried out 36 hours after ovulation
  • It is usually recommended to undergo 3 - 6 sessions prior to IVF (in-vitro fertilization) being considered
  • You may experience some abdominal cramps after insemination
  • There is a risk of multiple pregnancies

Success rates

According to a study in 2006, successful births from intra-uterine donor inseminations are as follows:
  • 15% for women under 35 years
  • 10.4% for women aged 35 - 39 years
  • 5.5% for women aged 40 - 42 years
  • 1.3% for women aged 43 - 44 years
  • no pregnancies resulted from those women over 44 years of age
