Male Infertility

Fertility is a biological function of both the husband and wife, who, through sexual intercourse, unite their gametes.  When a woman has difficulty achieving pregnancy, an evaluation for that problem must involve, not only her, but also her husband.  This evaluation can be helpful at giving important information to the couple so they may better understand the future capability of their procreative potential.  At the same time, it can be a complex and difficult area to work with.

The Creighton Model System plays a specific role for patients who have difficulty achieving pregnancy when the seminal fluid parameters are abnormal.  In such circumstances, identifying the time of fertility with accuracy will assist couples with severe oligospermia to achieve pregnancy.  In Figures 47-1 and 47-2, four examples of successful pregnancies in these circumstances are shown.  In Figure 47-1, the patient’s husband had a sperm count done on Day 10 of the pregnancy cycle.  His effective sperm count (ESC) was 189,666/cc.  This was not this patient’s first pregnancy, it was her fourth; however, they had more difficulty achieving this pregnancy than the others.  Nonetheless, the only treatment eventually implemented after she had been evaluated and found to be within normal limits was fertility-focused intercourse through the CrMS.

[Figure 1. Patient whose husband has severe oligospermia. Effective sperm count (ESC) was 189,666/cc at time of pregnancy using natural insemination and properly timed intercourse (From: Pope Paul VI Institute research, 2004).]In Figure 2, several similar examples are presented.  In Patient A, the effective sperm count was 30,000/cc.  In Patient B, the ESC was 116,850/cc and in Patient C, the ESC was 50,000/cc.  These examples are presented to show the CrMS and NaProTECHNOLOGY can be used to assist couples achieve pregnancy, even when the sperm count is severely decreased.

[Figure 2. Patients with severe oligospermia and successful pregnancy using properly timed intercourse and natural insemination: A) effective sperm count = 30,000/cc, B) effective sperm count = 116,850/cc, C) effective sperm count = 50,000/cc]











The normal sperm count should indicate that the number of sperm is 20 million/cc or greater and that the motility (the percentage of sperm that are moving) should be greater than 70 percent.  In addition, the morphology (the shape of the sperm) should exceed 60 percent.  With regard to the morphology, over the last 15 years, many laboratories have unwittingly changed their classification for the morphology of the sperm.  These laboratories have adopted what are referred to as the “strict Kruger criteria.”  Based upon a publication in 1988 by Kruger, a very strict classification system has been introduced for the shape of the sperm.  With this classification, the morphology is extremely low and still considered to be normal.  For example, in many cases, if the morphology is greater than 14 percent, it is considered to be normal.  In other words, using this system, 80 to 85 percent of the sperm could be considered to be morphologically abnormal and the sperm count could still be considered normal.  This, of course, does not make common sense.

What most people do not realize is that the Kruger system was specifically designed for people who are undertaking treatment by in vitro fertilization or one of the other artificial reproductive technologies.  In actual fact, the laboratories have adopted such an approach simply because it has been the general trend to do so.  And yet, many couples have no interest in pursuing the in vitro fertilization techniques.  Thus, they are obtaining information which is of very limited value to them.
