Male problems that prevent normal deposition of sperm into the vagina. Examples include premature ejaculation, impotence and retrograde ejaculation. |

Problems with the woman that prevent normal deposition of sperm into the vagina. Examples include painful intercourse and physical deformities. |
|
| 3. |
Cervical factors. Examples include a narrowed cervix and absent, abnormally thick or acidic cervical mucus. Intrauterine insemination will bypass cervical problems. |
|
| 4. |
Suboptimal semen quality. Artificial insemination can ensure that most of the sperm in an ejaculate of low volume will get past the vagina into the upper reproductive tract of the woman. If the number of motile sperm in the semen specimen is reduced, artificial insemination may improve the chance that pregnancy will occur. In order to yield a decent chance for conception, we must have at least two million actively progressing sperm in the specimen that we use for insemination. |

Use of frozen husband's sperm. Sperm that has been frozen and stored prior to sterilization, radiation or chemotherapy may be utilized for artificial insemination. |
