Effects of microorganisms on quality and some indices of semens of male patients with infertility in kano metropolis, Nigeria

Abstract

Both sexes are more or less equally involved in infertility problem.2 Men either alone or along with their female partners, contribute to 40–45% cases of infertility.3 Furthermore, infectious etiology involving bacteria, virus, fungi, and protozoa contribute to 15% of male factor infertility.4,5 Some of the microbes are acquired exogenously or endogenously and they could cause infertility in several ways: by damaging sperm motility, deterioration of spermatogenesis, altering the chemical composition of the seminal fluid by dysfunction of accessory sex glands, or by inducing autoimmune processes due to inflammation.6 Normal semen is composed of the fluids from the vas deferens, the seminal vesicles, the prostate gland and the mucous glands, especially the bulbourethral glands. The major bulk of the semen is seminal vesicle fluid (about 60 %), which is the last to be ejaculated and serves to wash the sperm out of the ejaculatory duct and urethra.7
