Intrauterine insemination (IUI)
Intrauterine insemination (IUI) is a specific type of artificial insemination used to treat infertility. This procedure involves placing sperm inside the uterus to increase the number of sperm reaching the fallopian tube. The goal of this method is to increase the fertilization chance. Low sperm count or decreased sperm mobility are the most common indications for IUI, however this procedure may be used to treat other conditions such as cervical condition, Ejaculation dysfunction or Unexplained infertility.
TESA (Testicular Sperm Aspiration)
TESA is a procedure which involves the retrieval of sperm for IVF or ICSI processes, by inserting a tiny needle through the scrotum skin. This method may be recommended for men with obstructive azoospermia (zero sperm count) or a blockage in their reproductive tract due to conditions such as vasectomy, infection or congenital abnormality. This procedure and its indications are similar to PESA; the difference is that in PESA the sperm is retrieved directly from the epididymis.
