Successful pregnancy after spermatid injection.
We present nine cases of spermatid intracytoplasmic injection for the treatment of non-obstructive azoospermia. In eight cases, no elongated spermatids or spermatozoa were found in previous spermiograms or testicular biopsies. In these patients, treatment was performed using ejaculated (n = 6) and testicular (n = 2) retrieved round spermatids (Sa type). In cases where ejaculated round spermatid...
متن کاملIncreased Fertilization Rates after In Vitro Culture of Frozen-Thawed Testicular Immotile Sperm in Nonobstructive Azoospermic Patients
Objective. To optimise the use of freeze/thaw testicular immotile spermatozoa from nonobstructive azoospermia patients and to analyse the outcome of intracytoplasmic sperm injection (ICSI) of such spermatozoa. Methods. Testicular specimens were retrieved and cryopreserved from forty patients with nonobstructive azoospermia and underwent one cycle with thawed spermatozoa (Group I) that led to pr...
متن کاملFertilization and embryo development to blastocysts after intracytoplasmic sperm injection in the rhesus monkey.
Notwithstanding the thousands of seemingly healthy children born after intracytoplasmic sperm injection (ICSI), it is not yet possible to conclude absolutely that the ICSI procedure might induce some altered development or that the ICSI protocol might not be improved even further. To address this in a clinically relevant system, the developmental potential of rhesus monkey embryos produced by I...
متن کاملFertilization and Embryo Development of Fresh and Cryopreserved Sibling Oocytes
Background The pattern of Islamic fasting differs from other forms of fasting, therefore its effect on health also differs. This research studies the effect of Islamic fasting on gonadotropin hormones around the time of the ovulatory cycle and ovulation. MaterialsAndMethods This self-controlled study was performed on 24 adult females. Blood sampling was performed during Ramadan and two months l...
متن کاملFertilization and pregnancy outcome with intracytoplasmic sperm injection for azoospermic men.
The evident ability of the intracytoplasmic sperm injection (ICSI) procedure to achieve high fertilization and pregnancy rates regardless of semen characteristics has induced its application with spermatozoa surgically retrieved from azoospermic men. Here, ICSI outcome was analysed in 308 cases according to the cause of azoospermia; four additional cycles were with cases of necrozoospermia. All...
