Percutaneous epididymal sperm aspiration ( PESA) is a technique used to determine sperm counts in the event of a possible blockage of the vas deferens. It is an alternative to microepidydimal sperm aspiration (MESA), and aims to address the technical difficulty and cost of MESA. [ 1] A small needle is inserted through the skin of the scrotum to ...
Testicular sperm extraction. Testicular sperm extraction (TESE) is a surgical procedure in which a small portion of tissue is removed from the testicle and any viable sperm cells from that tissue are extracted for use in further procedures, most commonly intracytoplasmic sperm injection (ICSI) as part of in vitro fertilisation (IVF). [1]
Intracytoplasmic sperm injection (ICSI / ˈɪksi / IK-see) is an in vitro fertilization (IVF) procedure in which a single sperm cell is injected directly into the cytoplasm of an egg. This technique is used in order to prepare the gametes for the obtention of embryos that may be transferred to a maternal uterus.
This finding paved the way for genetic assessments as part of the clinical assessments for infertile men.Dr. Patrizio also co-pioneered the microsurgical epididymal sperm aspiration (MESA) technique to improve male fertility and developed whole ovary cryopreservation via multi-thermal gradient for fertility preservation in women.

The epididymis is a long, coiled tube that stores sperm and transports it from the testes. It appears as a curved structure on the posterior (back) margin of each testis. It is comprised of three ...
A spermatocele is an often pain-free benign cyst that occurs close to a testicle. It may also be known as a spermatic or epididymal cyst. The cyst forms in the epididymis. The epididymis is a ...
