    We have had four failed attempts at treatment. They now tell us that my husband has 'clumping' of his sperm. Please could you tell me what we can do to help this? Does cooling the scrotum work? I haven't really got enough information to be able to help you.

    Sperm agglutination: Prevalence and contributory factors

    In an earlier work done in our laboratory, we have been able to isolate a sperm agglutinating strain of Escherichia coli from the semen sample of a male attending infertility clinic. Further, factor responsible for sperm agglutination SAF was isolated and purified, and, using SAF as a tool, corresponding SAF binding receptor from human spermatozoa has been purified. SAF induced impairment of sperm parameters, and infertility was observed to be due to interaction of SAF with sperm surface receptor component as, when purified receptor was introduced, receptor completely inhibited all the detrimental effects induced by SAF. From these results, it could be concluded that interaction of SAF with spermatozoa is receptor mediated. The cause-effect relationship between bacterial infections and infertility is still being debated [ 1 ]. Various microorganisms are well-known causative agents of genitourinary infections such as Escherichia coli , Staphylococcus aureus [ 2 ], Ureaplasma urealyticum , Mycoplasma hominis, and Chlamydia trachomatis [ 3 ] which have the ability to interact directly with spermatozoa. Escherichia coli represents the most frequently isolated microorganism in patients with genitourinary infections and male accessory gland infections MAGIs [ 4 ].

    Imprisonment-associated sperm clumping and male infertility

    Tutor A. Spermatozoa were first described by Leeuwenhoek in the 17th century but it was not until that the sperm count was found to be associated with fertility potential Since that time a variety of sperm tests and semen parameters have been developed with the hope of clarifying whether or not a man could impregnate his partner. MacLeod , MacLeod and Gold , Eliasson and Hellinga , have led the scientific basis of conventional analysis of spermatozoa and the techniques recommended by them are still considered the reference for more advanced methods 6. Semen analysis comprises a set of descriptive measurements of spermatozoa and seminal fluid parameters that help to estimate semen quality 4.
