High fructose concentrations provide nutrient energy for the spermatozoa as they travel through the female reproductive system. When muscles in the penis contract to stop the inflow of blood and open outflow channels, erection is reversed. The procedure for a percutaneous biopsy will depend on the type of needle used — a core needle or a fine needle. The combination of intracytoplasmic sperm injection together with various testicular sperm retrieval techniques, including conventional testicular sperm extraction TESE , microdissection TESE micro-TESE and fine needle aspiration FNA , have revolutionized treatment for these men.
