Immune testing in fertility practice: truth or deception?

Area of Science:

• Reproductive Immunology
• Infertility Research
• Pregnancy Loss Studies

Background:

• Immunology plays a critical role in reproductive success and failure.
• Immune-mediated factors are implicated in various stages of pregnancy.
• Immune testing is frequently used for unexplained infertility and recurrent pregnancy loss.

Purpose of the Study:

• To review controversial data on immune testing in fertility practice.
• To determine which immunological tests are scientifically warranted.
• To analyze immune testing in patients with recurrent pregnancy loss and early miscarriage.

Main Methods:

• Review of existing scientific evidence on immune testing in reproductive failure.
• Analysis of studies investigating the association between immune abnormalities and early reproductive loss.
• Evaluation of the diagnostic and therapeutic utility of immunological tests.

Main Results:

• Rigorous studies have not established a cause-and-effect relationship between abnormal immune tests and early reproductive failure.
• Significant variation exists in study methodologies, patient populations, and the specific tests employed, leading to inconsistent associations.
• The clinical significance of many immunological test abnormalities in early reproductive failure remains uncertain.

Conclusions:

• Widespread immune testing in clinical fertility practice is not supported by current scientific data.
• There is considerable variability in patient selection, test interpretation, and treatment protocols.
• Immunological treatments for reproductive failure lack confirmed benefits and may pose risks.
