Filter by:Investigate the effect of intratesticular injection of autologous platelet rich plasma (PRP) on sperm retrieval rates and IVF outcomes in infertile men who already underwent a negative sperm retrieval. Currently, there is no alternative treatment after failed TESE. Prior series suggest that intratesticular PRP injections may improve TESE outcomes. We hope to determine whether PRP is an effective treatment for this patient population.
Study question: Can enough testicular tissue be aspirated for sperm retrieval in non-obstructive azoospermia (NOA), using a wide bore 14-G Standard IV cannula in comparison to micro-TESE? Summary answer: Standard IV cannula Aspiration (SIVCA) can yield an ample amount of testicular tissue sufficient for sperm retrieval through a single puncture site on the scrotum.
This study will evaluate the safety and feasibility of the ADAM System for implantation into the vas deferens in 60 healthy males at 3 sites. This is a prospective, non-randomized, open label interventional trial.
Azoospermia is defined as the complete absence of spermatozoa in the ejaculate. Two-thirds of azoospermic patients have non-obstructive azoospermia (NOA); the latter comprises up to 10% of infertile men overall. NOA is an untreatable testicular disorder associated with spermatogenic failure and is the most severe male infertility phenotype. Among the available surgical sperm retrieval techniques, microdissection testicular sperm extraction (micro-TESE) is the procedure of choice due to its high sperm retrieval success rates (SRR), minimal tissue extraction, and low complication rates. Even with the use of micro-TESE, the likelihood of retrieving sperm in patients with NOA remain suboptimal (40% to 60%). Hypogonadism is detected in approximately half of the patients with NOA. Given the role of intratesticular testosterone (ITT) levels for spermatogenesis, some studies have explored the clinical utility of testosterone optimization by medical therapy before sperm retrieval. Moreover, some investigators have hypothesized that the follicle-stimulating hormone (FSH) reset might increase the expression of FSH receptors and improve Sertoli cell function. Hormonal therapy with human chorionic gonadotropin (hCG) has been shown to improve ITT production and decrease FSH levels in patients with NOA. The investigators, therefore, designed an observational cohort study aiming to evaluate whether hormone stimulation with gonadotropins (e.g., hCG alone or combined with FSH) previous to micro-TESE increases sperm retrieval rates in hypogonadal infertile men with NOA, candidates for sperm retrieval. The investigators hypothesize that optimizing ITT production and resetting FSH levels may improve spermatogenesis and successful sperm recovery.
Azoospermia is a word meaning to ejaculates with no spermatozoa without a definite underlying cause .1% of men has azoospermia, representing nearly 10 to 15% of all infertile men. The azoospermia is a major concern in our community. There is no actual epidemiological studies to estimate the actual numbers in Egypt. Azoospermia has several classifications, pre-testicular, testicular & post-testicular cause .The semen analysis is the main investigation done for these patient .The treatment methods range from hormonal therapy to surgery or ICSI . The imaging modalities has developed greatly in the last 3 decades. That it became in several setting as a bedside test or investigation. The main modalities used in azoospermia are scrotal ultrasound, TRUS and MRI. The first TRUS was introduced 1957.
A comparison of reproductive and obstetrical outcomes is retrospectively performed among couples that underwent ICSI-TESE cycles for obstructive and non obstructive azoospermia between January 2001 and December 2019.
The objective of this study is to determine if the lack of exposure to sperm antigens is associated with worse maternal and neonatal outcomes in pregnancies obtained after ICSI (intracytoplasmic sperm injection)-TESE (testicular sperm extraction) for obstructive azoospermia. The primary outcomes that will be investigated include: - Maternal outcomes: live birth rate (LBR), abortion rate, and the rate of the main obstetrics complication, such as pre-eclampsia, gestational hypertension and diabetes mellitus. - Neonatal outcomes: gestational age, prematurity rate, birth weight, sex ratio, 1- and 5-min APGAR, birth defects.
This study aims to investigate the outcome of ICSI after using LAISS for selection of viable immotile testicular sperm in azoospermic infertile men. Patients will be randomly assigned to 2 groups. In (LAISS) group, viable immotile testicular sperms will be selected before ICSI using laser assisted immotile sperm selection (study group). In (HOST) group, viable immotile testicular sperms will be selected before ICSI using hypo-osmotic swelling test (control group).
The aim of the study is to assess if seminal TEX 101 can predict the restoration of spermatogenesis and appearance of sperms in the ejaculate after micro-surgical varicocelectomy among azoospermic patients.
*Evaluate the predictive value of AMH, Testosterone,Estradiol,Testosterone Estradiol ratio for TESA and TESE outcome in non obstructive azoospermic patients.
