You may feel slight discomfort and tenderness on the scrotum for the first 24 to 48 hours. According to the same authors, other advantages of PESA in relation to MESA are minimal discomfort for the patient, and lesser complication rate when compared to open surgery. Fertility centre in Madrid, Spain. In the TESA group, 2 miscarriages and 1 ectopic pregnancy occurred, while 9 gestations were carried in full term. Counting of spermatozoa was not accomplished due to the small quantity of material available.
TESA – TESE ICSI (Testicular / Epididymal Sperm Aspiration or Extraction)
Open Testicular Biopsy is an invasive, operative procedure used to obtain sperm by surgically opening the scrotum and removing a small amount of Seminiferous Tubules from the testicle. It is because of these reasons that we rarely offer TESA to our patients. However, this has raised much speculation and concern about the use of genetic material from a still-evolving germ cell for clinical purposes before the system has been appropriately investigated and its genetic stability examined in animal models. It is precisely these situations that require advanced reproduction technologies such as ICSI to establish a pregnancy. If the technician finds sperm during your microTESE, your sperm will be extracted and frozen so they can be used in future reproductive treatments, like in-vitro fertilization IVF with intracytoplasmic sperm injection ICSI.

Authors reported that the postoperative T levels in rats, after orchiectomy, remain at The analyses were performed at x magnification. Four non-randomized rats were subjected to orchiectomy at different intervals after surgery: Sperm retrieval and fertilization in repeated percutaneous epididymal sperm aspiration.

The tunica albuginea is opened transversely along the equator of the testicle. The amount of tissue obtained is low because the thin needle removes only a thin sliver to tissue. While this is "blind", since it's possible to sample many more areas of the testes we routinely perform over 10 microbiopsies using this technique, even from very tiny testes this technique is at least as effective as Dr Schlegel's in recovering testicular sperm. However, this has raised much speculation and concern about the use of genetic material from a still-evolving germ cell for clinical purposes before the system has been appropriately investigated and its genetic stability examined in animal models. MESA allows for an extensive collection of sperm as compared to aspiration techniques, and is the preferred method of retrieval for men with congenital bilateral absence of the vas deferens CBAVD. You can then use your sperm for IVF in-vitro fertilization.
