Progesterone treatment of boar spermatozoa improves male pronuclear formation after intracytoplasmic sperm injection into porcine oocytes.
Boar spermatozoa were prepared for intracytoplasmic sperm injection (ICSI) by two different treatments to facilitate sperm chromatin decondensation and improve fertilisation rates after ICSI in pigs: spermatozoa were either frozen and thawed without cryoprotectants, or treated with progesterone. Morphological changes of the sperm heads after the treatments were examined and then the activation ...
متن کاملO-13: Evaluation of Leptin Concentration in Seminal Plasma and Its Correlation with Reactive Oxygen Species, Lipid Peroxidation and Pronuclear Formation in Candidates for ICSI Treatment
Background Leptin, as a key hormone in energy homeostasis, plays an important role in reproduction and male fertility. However, its negative or positive effect on sperm quality and assisted reproduction technique is still controversial. The aim of this study was the comparison of seminal leptin concentration in selected couples with male and female factor for intracytoplasmic microinjection (IC...
متن کاملMale Pronuclear Formation using Dog Sperm Derived from Ectopic Testicular Xenografts, Testis, and Epididymis
BACKGROUND Testis tissue xenografting and the resultant sperm in a xenograft may provide a unique approach to rescue the genetic material of males that die prematurely and is a model for the study of human spermatogenesis and can represent an alternative approach for fertility preservation in cancer patients. This study was aimed to evaluate the xenogenic dog sperm in formation of male pronucle...
متن کاملMale Pronuclear Formation and Embryo Development Following Intracytoplasmic Injection of Ovine Pretreated Sperm
Background Failure of Male Pronucleus (MPN) formation is a major concern in the success of Intracytoplasmic Sperm Injection (ICSI) in some species. Despite the conducted unsuccessful efforts to improve ICSI efficiency in ovine, the present study was aimed to improve MPN formation and embryo development in ovine ICSI procedure through accompaniment of sperm pretreatment with co-injection of some...
