Artificial insemination is the process by which an egg is fertilized in the absence of intercourse. Intercourse to achieve pregnancy is termed "natural conception." So, it follows that means other than natural conception could be regarded as "artificial" insemination.
Ideally, a couple or woman under the age of 35 should attempt natural conception for 1 year before seeking fertility assistance. For women over the age of 35, 6 months is the current standard. Talk to your gynecologist about Artificial Insemination to see if this is the right assistive reproductive technology for you.
