Azoospermia is the most common form of male factor infertility, due to which sperms are retrieved for intra-cytoplasmic sperm injection ICSI under general or local anesthesia. The aim of the present study was to compare the efficacy of general and local anesthesia in an attempt to extract a sufficient quality of sperm for men with azoospermia, who intend to undergo ICSI. A total number of 50 patients with azoospermia, who were within the age range ofwere randomly scheduled for testicular sperm extraction with either general or local anesthesia before ICSI.
Language: English French. An adequate semen volume of ejaculate fluid is required to transport sperm into the female reproductive tract and allow for fertilization of the oocyte. Thus, seminal fluid volume is an important part of the semen analysis done to investigate male infertility.
Sperm harvesting is entirely different from a diagnostic testicular biopsy because, in this setting, the goal is not to identify what is happening in the testis but instead it is to find sperm. Only men with no sperm in their ejaculate azoospermia need to have sperm retrieved directly from the testis or epididymis. This may involve a simple aspiration for men who have a blockage or require much more extensive sampling of the testis for men who have a sperm production problem.
There are many causes for male infertility. Up to 15 percent of men with fertility issues have no sperm when they ejaculate. About half the time this is due to a blockage of the reproductive tract. Often a testicular biopsy is required to determine if the lack of sperm is due to no sperm being produced or due to a blockage.

What Causes Aspiration Pneumonia? My father is hospitalized with aspiration pneumonia. What causes this?
Cystic fibrosis CF is a genetic disease that affects multiple organ systems from the digestive tract to the lungs. In men, CF causes the vas deferens to atrophy early in embryologic development. Therefore, men with CF are born without a vas deferens.
Spermatozoa were aspirated from the proximal vas deferens of five men with persistent anejaculation which could not be overcome by using a vibrator or electro-ejaculation. Three men had spinal cord injury, one man had undergone a pelvic lymphadenectomy, and in one of them the aetiology was unknown. Fairly good numbers of spermatozoa from 7.
Enhancing Success of Assisted Reproduction. The ICSI has become method of choice to achieve fertilization. Fertilization is possible in cases in which the sperm motility and ability to penetrate the zona pellucida are impaired. This suggests that, despite injecting sperm into mature oocytes, failed fertilization still occurs.
