Male Accessory Gland Infection (MAGI), also known as Male Accessory Gland Inflammation,[1] is a condition with signs of inflammation involving one or more sites in the male genital tract. Diagnosis is made according to parameters defined by the World Health Organisation, and it is particularly made in relation to infectious or inflammatory causes of male infertility.

Although it is usually caused by infection spreading from the urethra, non-infectious causes also exist.

Definition

MAGI includes infections (bacterial, viral, fungal etc) involving one or more of the following male genital organs or tracts:[2]

Diagnosis

As infection has a negative impact on the secretory function of the accessory glands, findings that could indicate the presence of MAGI include:[3]

WHO criteria

MAGI can be diagnosed when there are two or more factors present that meet criteria defined by the World Health Organization (WHO):[1][4]

Factors Description For positive diagnosis
A History of:

Physical signs:

 (i) Any one Factor A feature
    plus
(ii) one feature from either Factor B or Factor C
B Prostatic fluid:
  • abnormal expressed prostatic secretion (EPS)
  • abnormal voided urine after prostate massage (VB3)
 (i) Either one of the Factor B features
    plus
(ii) one feature from either Factor A or Factor C
C Semen:
  • leukocytes ≥ 1x106/mL
  • semen culture with significant growth of pathogenic bacteria
  • abnormal semen appearance
  • increased semen viscosity (hyperviscosity)
  • increased pH
  • abnormal biochemistry of the seminal plasma
 Any two Factor C features

or

(i) any one Factor C feature
    plus
(ii) one feature from either Factor A or Factor B

Biomarkers

One study has proposed that elevated levels of soluble urokinase-type plasminogen activator receptor (SuPAR) in seminal plasma might be useful as a marker for MAGI.[5]

Causes

The main infectious agents are Enterobacteriaceae (such as Escherichia coli and Klebsiella), Neisseria gonorrhoeae and Chlamydia trachomatis.[2]

One study has shown that men with MAGI who have lower serum levels of total testosterone tend to have a more complicated form of MAGI, such as involving more than one site, than those with normal levels.[6]

Complications

Potential complications include:[2][3][7]

These complications can result in sexual dysfunction[7] and male subfertility.[4][8]
