Male Infertility- Surgical Sperm Retrieval, Vasectomy Reversal, and Azoospermia
|
Surgical Sperm Retrieval- Click here to learn more about surgically retrieving sperm from the testicle
or epididymis for obstructive azoospermia (no sperm due to blockage after vasectomy)
or for non-obstructive azospermia (no sperm on ejaculation with no prior vasectomy).
PREG has an arrangement with a local urologist to perform the surgical sperm retrieval
in PREG's surgery suite in Greenville with PREG's andrologist available to perform
immediate sperm cryopreservation (if sperm suitable for cryopreservation is found). The
cryopreserved (frozen) sperm can then be used later with the intracytoplasmic
sperm injection (ICSI) technique in an IVF cycle to achieve fertilization of the
woman's eggs obtained by transvaginal ultrasound follicle aspiration resulting
in embryos.
Vasectomy Reversal- Click here to learn more about vasectomy reversal (vasovasotomy). PREG does
NOT perform this procedure. A urologist would perform a vasectomy reversal. Before
vasectomy reversal is performed, evaluation of the female partner's reproductive
potential is recommended. The alternative to vasectomy reversal - epididymal or
testicular sperm aspiration or extraction and IVF with ICSI- should be presented
and discussed. The prognosis for success after vasectomy reversal declines progressively
as the interval between vasectomy and its reversal increases with significantly
lower pregnancy rates when reversal was performed 10-15 or more years after vasectomy.
The inverse relationship between success rates and the interval of obstruction
may reflect progressive testicular damage. The age of the female partner has important
prognostic value with women older than 37 having a progressive decline in fertility
and IVF may be the better option. Other female factors such as tubal disease,
anovulation, diminished ovarian reserve, or endometriosis may make IVF with ICSI
the more preferred route to achieve a successful pregnancy.
Evaluation of the Azoospermic Male- Click here to learn more about Azoospermia (No spermatozoa (sperm) seen on
2 separate semen analyses, even after centrifugation of the semen sample in an
attempt to concentrate the sperm if present in very low numbers (oligospermia)).
Azoospermia occurs in approximately 1% among all men and 10-15% among infertile
men. |
