MESA is a microsurgical epididymal sperm aspiration procedure performed under general anesthesia utilizing the operating microscope. Patients usually cryopreserve sperm for future IVF/ICSI cycles.
An incision is made in the scrotum and the epididymis tubules are dissected under an operating microscope. Once a site with motile sperm is identified aspiration is done from that area until all sites are exhausted.
What is MESA?
MESA is an academic enrichment program for community college students who want to pursue degrees in science, technology, engineering or math (STEM). Students receive academic support throughout their education pathway so that they will excel in their field of study and have the opportunity to transfer to four-year institutions.
Early Spanish explorers were fascinated by the flat-topped mountains they saw across the Southwestern United States. These landforms looked like tabletops and were named mesas, meaning “tables.” The rock layers that form mesas have a hard top layer that is resistant to erosion. The softer, less-resistant layers on the sides erode into valleys and slopes.
MESA, PESA and TESA are sperm retrieval techniques that can be performed under general anesthesia to improve fertility in men with a low number of motile sperm in their ejaculate or obstructions in the epididymis or vas deferens. These procedures involve opening the scrotum to extract testicular tissue from which sperm is retrieved.
How is MESA performed?
The MESA and PESA procedures allow men with a blockage in the vas deferens or the epididymis to obtain sperm for IVF or ICSI. The sperm is isolated from the testicular fluid and the healthiest spermatozoa are retrieved. The sperm is then prepared and evaluated in the laboratory and frozen for future use.
MESA (microsurgical epididymal sperm aspiration) is the preferred surgical method for obtaining sperm at Innovative Fertility Center. MESA provides superior fertilization and clinical pregnancy rates compared to TESE, and it is also less invasive to the patient.
MESA helps community college students from educationally disadvantaged backgrounds excel academically, transfer to four-year institutions and become tomorrow’s scientists, engineers and doctors. Students develop leadership skills through community service and gain academic support from faculty, on-campus resources and professional organizations. The program also helps students create a comprehensive educational plan and identify long-term support systems. MESA is a collaborative effort of the Chancellor’s Office, University of California and local communities.
What are the benefits of MESA?
Infertile men often have few or no motile sperm in their ejaculate, or the sperm is blocked from transporting to the ejaculate (azoospermia). MESA is performed under a surgical microscope and allows the retrieval of lots of healthy sperm. These sperm can be used with other fertility treatments to improve a man’s chances of fertilization.
The obliterative MESA technique is preferred to aspiration techniques in that it maximizes the amount of sperm retrieved from the epididymis. It also does not damage the sperm tubes. Arizona Center for Fertility Studies has often used MESA sperm in conjunction with IVF and Intracytoplasmic Sperm Injection (ICSI) to achieve excellent pregnancy and fertilization rates.
MESA is usually done as a pre-operation procedure in patients with azoospermia who are having problems getting a partner or who need IVF. However, MESA can also be done as a rescue procedure after unsuccessful percutaneous PESA. A recent contemporary study found that testicular sperm are no better than those obtained by MESA in terms of IVF ICSI results, including fertilization.
What are the disadvantages of MESA?
While Mesa has some advantages, it is also not without its downsides. For one, the city has a high cost of living and this may make it difficult for people to afford the amenities that they need. This includes the cost of housing, transportation, utilities, and health care.
Another downside is that the city does not have a good public transportation system. This means that people who live in Mesa have to rely on their cars for transportation. This can lead to higher gas and maintenance costs.
The city also does not have a lot of nightlife activities and this can be frustrating for people who like to go out and have fun. Finally, the weather in Mesa can be very hot during the summer and cold during the winter. This can be uncomfortable for people who are used to a more temperate climate.mesa tesa
