Conjugal artificial insemination is indicated for couples with: slight male factor, slight ovaric disfunction, slight endometriosis, when there is no apparent reason for infertility, and when after thre or four cycles of ovaric stimulation and planned coitus pregnancy has not been achieved.

During the conjugal artificial insemination cycle, gonadotropins are administered subcutaneously, to stimulate follicular development.

Through ultrasound scan monitoring the development of the follicular growth is followed. When the follicles are mature a medication that produces ovulation is administered.

On the day of ovulation, the husband's semen is processed in the laboratory, to improve its quality, especially the spermatozoid mobility. Once the semen has been improved and is ready it is introduced in the uterus with a very fine catheter. From here, the spermatozoids travel to the fallopian tubes where they fertilize the ovule.
