There is controversy about whether or not the anatomic source of sperm used for ICSI cycles impacts reproductive outcomes. An analysis of the total number of straws Figure 4 showed that cryopreserving was not possible due to low aspirate quality in only two men. The mean global motility of the available samples decreased from Opaque, yellow tubules typically contain only sperm heads and debris and should be avoided. In azoospermic patients without disorders in spermatogenesis, the following indications for microsurgical epididymal sperm aspiration MESA are generally accepted: In five cases, embryos aborted in the first trimester. Occasionally rare sperm may be found in the ejaculate that may be used for ICSI and obviate the need for retrieval.
Microsurgical epididymal sperm aspiration: indications, techniques and outcomes
This is a preview of subscription content, log in to check access. If glass micropipettes are not available, epididymal fluid may alternatively be collected by gentle aspiration using a 1-ml syringe that has been prefilled with a small volume of sperm transport fluid and attached to a gauge angiocatheter. All labs and office visits are included in your package plan. Sperm are unlikely to be found in the epididymis when sperm production is severely impaired, and puncture of a non-dilated epididymal tubule is extremely technically challenging and unlikely to be successful.
UHC Member's may consult with their physician to determine if Gonal F is appropriate for their treatment plan hCG - Encourages the eggs' final development prior to retrieval. ICSI outcomes in obstructive azoospermia: During MESA, sperm-containing epididymal fluid is aspirated from optimal areas of the epididymis that are selected and sampled using high-power optical magnification provided by an operating microscope. During this phase of your treatment, you will be placed on a specific combination of medications that your team has created based upon your pre-cycle testing and your history.
There appear to be no data available concerning the amount of progressively motile epididymal spermatozoa. Example wet-mounts of aspirated epididymal fluid are seen in Figures 2a and 2b. This procedure is used for cases of obstructive azospermia. These data provide evidence that during asynchronous epididymal sperm aspiration, as already claimed by Oates et al.
