Immunoglobulins in human seminal plasma.

Area of Science:

• Immunology
• Andrology
• Reproductive Medicine

Background:

• Immunoglobulins (IgG, IgA, IgM) and secretory piece (SP) play roles in mucosal immunity.
• Seminal plasma composition can be affected by various physiological and pathological conditions.

Purpose of the Study:

• To quantify immunoglobulins and secretory piece in human seminal plasma.
• To investigate changes in immunoglobulin levels in healthy volunteers, vasectomized subjects, and patients with andrological disorders.

Main Methods:

• Single radial immunodiffusion technique was employed.
• Samples were analyzed from healthy volunteers, post-vasectomy subjects, and patients with andrological conditions.

Main Results:

• Normal subjects consistently showed IgG and IgA; IgM was present in trace amounts.
• Vasectomized subjects exhibited a temporary increase in IgG and IgA post-surgery.
• Andrological patients with antisperm antibodies or genital infections displayed elevated Ig levels.

Conclusions:

• Seminal plasma immunoglobulin levels can serve as indicators in certain andrological diseases.
• The local immunocompetent system is significant in managing some andrological disorders.
• Secretory piece assay data supports the role of the local immune system.
