Efficacy of intracytoplasmic sperm injection using intentionally cryopreserved epididymal spermatozoa.
Microsurgical epididymal sperm aspiration was a great advance in the therapy of patients with non-reconstructable, obstructive azoospermia, most notably congenital bilateral absence of the vas deferens. Using conventional in-vitro fertilization, pregnancies were rarely achieved because the rate of oocyte fertilization was extremely poor. However, the use of retrieved spermatozoa in conjunction ...
متن کاملTesticular versus epididymal spermatozoa in intracytoplasmic sperm injection treatment cycles.
BACKGROUND Normal fertilization and ongoing pregnancy can be achieved using intracytoplasmic sperm injection (ICSI), even with severely immature spermatozoa. However, the published literature documents conflicting results as to the outcome of ICSI. METHODS Surgical extraction of spermatozoa in 111 ICSI treatment cycles performed over five years at the Assisted Conception Unit (ACU), Universit...
متن کاملCorrelation between testicular histology and outcome after intracytoplasmic sperm injection using testicular spermatozoa.
A comprehensive study is presented of a series of 124 infertile men undergoing testicular sperm retrieval for intracytoplasmic sperm injection (ICSI). In this study we correlated the histological changes observed in the testicular tissue with the results of the wet preparation and the outcome after ICSI using testicular spermatozoa. In all patients with normal spermatogenesis and hypospermatoge...
متن کاملEctopic ovarian pregnancy after intracytoplasmic sperm injection with testicular spermatozoa - a case report
Ovarian ectopic pregnancy is a rare event in both natural and assisted human reproduction settings. There are few reports of this event after in vitro fertilization. Diagnosis can be challenging, since it requires specific medical expertise. Patients with this condition call for careful management during treatment so as to not affect their fertility potential. This paper describes the case of a...
متن کاملMultiple pregnancies obtained by testicular spermatid injection in combination with intracytoplasmic sperm injection.
Recent studies have shown that the injection of spermatid cells into the human oocyte can result in normal fertilization, embryo development and even delivery of live, healthy offspring. In our study, 23 azoospermic cases with severe spermatogenetic defects in their testicular biopsy are presented. The serum follicle stimulating hormone (FSH) concentrations and histopathological results of thes...
