Which sperm retrieval procedure is recommended?
Chronic epididymitis: impact on semen parameters and therapeutic options.
MESA collects sperm by aspirating fluid from the epididymis of the male reproductive tract. Reproductive toxicity and tissue concentrations of low doses of 2,3,7,8-tetrachlorodibenzo- p -dioxin in male offspring rats exposed throughout pregnancy and lactation. The main sign of low sperm count is the inability to conceive a child. Testicular torsion: Testicular torsion, or twisting of the testicle resulting in a strangulation of the blood supply, occurs in men whose tissue surrounding the testicle is not well attached to the scrotum. Urology ; — However, Sertoli cell changes were only seen at high doses, which are well beyond the concentrations reported to induce changes in DSP and epididymal sperm counts Mably et al. Dioxin exposure and spermatogenesis.

Left-sided grade 3 varicocele may affect the biological function of the epididymis. Philadelphia: Lippincott-Raven; The variable results for DSP are more difficult to interpret because sperm production can be affected by many factors, including nutrition, infection, and general health of the animal, as well as time from last ejaculation and toxicant effects on the hypothalamic-pituitary-testicular axis. Proliferation and functional maturation of Sertoli cells, and their relevance to disorders of testis function in adulthood. Gorelick JI, Goldstein M.

The bacteria can then move backwards through the genital tract and cause an infection of the epididymis.
