In cryptozoospermia or severe oligozoospermia is sperm freezing useful?
BACKGROUND Intracytoplasmic Sperm Injection (ICSI) is an Assisted Reproduction Technique (ART) which offers the chance to conceive to patients presenting very low sperm counts (cryptozoospermia/severe oligozoospermia). Sperm freezing before the oocyte pick-up, can prevent from a lack of spermatozoa on the day of the ICSI. It can avoid the cancellation of the ICSI or the use of TESE (Testicular ...
متن کاملDifferences and similarities between extremely severe oligozoospermia and cryptozoospermia in intracytoplasmic sperm injection
Patients with extremely severe oligozoospermia (ESO) and cryptozoospermia (CO) are suitable using intracytoplasmic sperm injection (ICSI) as an infertility treatment. However, some andrologists are confused to distinguish ESO and CO in clinic diagnose. This study was designed for the first time to evaluate and compare patients with ESO and CO to determine whether these are useful clinical disti...
متن کاملCryptozoospermia with normal testicular function after allogeneic stem cell transplantation: a case report.
One of the most frequent consequences of allogeneic haemopoietic stem cell transplantation (allo-SCT) in both males and females is gonadal insufficiency. We report the case of a 27-year-old myelodysplastic male who developed azoospermia after allogeneic transplantation of haemopoietic stem cells from his HLA-identical sister. Post-transplant azoospermia was alternated with intermittent severe o...
متن کاملCase study of a patient with cryptozoospermia associated with a recessive TEX15 nonsense mutation
screening was carried out according to the European Academy of Andrology (EAA) guidelines by real-time fluorescent PCR using the Y Chromosomal Microdeletion Test Kit (Shanghai Tellgen Corporation, Shanghai, China), which detected the sY84 and sY86 sequence-tagged sites (STSs) of azoospermia factor a (AZFa), the sY127 and sY134 STSs of AZFb, and the sY254 and sY255 STSs of AZFc. All six STSs wer...
متن کاملIntracytoplasmic Sperm Injection Outcomes with Freshly Ejaculated Sperms and Testicular or Epididymal Sperm Extraction in Patients with Idiopathic Cryptozoospermia
BACKGROUND Cryptozoospermia (CO) is a situation in which spermatozoa cannot be observed in a fresh semen sample unless an extended centrifugation and microscopic search are performed. CO patients are suggested to use only intracytoplasmic sperm injection (ICSI) as infertility treatment. But still there is debate about the choice of sperm source in cryptozoospermic men candidate for ICSI. OBJE...
