Homologe Intrauterine Insemination

Here it is important to stimulate the growth of one or two follicles using gentle hormone therapy. The growth and structure of the endometrium are constantly monitored by ultrasonic testing. Ovulation can be predetermined by performing ovulation tests and measuring both follicle size and endometrium thickness. When the follicles reach a certain size, ovulation is induced through medication.

The extracted sperm (from masturbation) is specially prepared in the laboratory. The sperm is implanted into the uterus through the cervix by a thin, flexible catheter; the patient experiences only minimal pain or discomfort.

The chances of fertilization increase by shortening the path the sperm have to travel. The chance for successful pregnancy with this method is 15–20% per cycle.
