Best Doctor List Near You for Sperm Extraction in Caxias do sul

Sperm extraction is a medical procedure used to retrieve sperm directly from the male reproductive tract when sperm cannot be collected through ejaculation. This technique is often employed in cases of male infertility where there are blockages or other issues preventing the release of sperm in the ejaculate. The procedure can be necessary for men with conditions such as azoospermia (absence of sperm in the ejaculate), obstructive azoospermia (blockage in the reproductive tract), or those who have undergone certain medical treatments that impair sperm production. Several methods of sperm extraction are used, including percutaneous epididymal sperm aspiration (PESA), testicular sperm extraction (TESE), and microdissection testicular sperm extraction (MicroTESE). In PESA, sperm is aspirated from the epididymis using a fine needle. TESE involves a surgical procedure to remove small samples of testicular tissue to locate and extract sperm, while MicroTESE uses a microscope to guide the extraction of sperm-producing tissue from the testicles. While sperm extraction can be highly effective in providing sperm for use in assisted reproductive technologies such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), it carries potential complications. These include bleeding, infection, and damage to the reproductive tissues, which could affect future fertility. Additionally, there is a risk that no viable sperm may be retrieved, necessitating alternative fertility treatments. Despite these risks, sperm extraction offers valuable options for men facing severe fertility issues, providing opportunities for biological parenthood.
