The ability of the hemizona assay to predict human fertilization in different and consecutive in-vitro fertilization cycles
(1993)
The objective of this prospective study was to examine the ability of the hemizona assay (HZA) to predict fertilization outcome of mature, pre-ovulatory oocytes under in-vitro fertilization (IVF) conditions. Since a large ...
A prospective study on the predictive value of normal sperm morphology as evaluated by computer (IVOS)
(1996)
Objective: To evaluate the IVOS (Hamilton Thorne Research Version 2.1 Dimension Program, Beverly, MA) system's ability to predict fertilization in vitro in a prospective study. Design: A prospective clinical study. Setting: ...
Clinical importance of zona pellucida-induced acrosome reaction and its predictive value for IVF
(2001)
The study aimed to establish zona pellucida induced acrosome reaction response (ZIAR) among 35 couples with normal and G-pattern sperm morphology and repeated poor fertilization results during assisted reproduction treatment. ...
Sperm chromatin packaging as an indicator of in-vitro fertilization rates
(2000)
The development of a sequential diagnostic schedule for patients consulting for infertility disturbances would be an ideal method of approach for clinicians in the absence of an aetiological or pathophysiological diagnosis. ...
Localization of tyrosine phosphorylated proteins in human sperm and relation to capacitation and zona pellucida binding
(2003)
Mammalian sperm must undergo a process known as capacitation before fertilization can take place. A key intracellular event that occurs during capacitation is protein tyrosine phosphorylation. The objective of this study ...
Zona pellucida induced acrosome reaction, sperm morphology, and sperm-zona binding assessments among subfertile men
(2002)
Purpose: The study aimed to evaluate the relationship between the zona pellucida induced acrosome reaction (ZIAR) and (i) percentage normal spermatozoa as well as (ii) sperm-zona pellucida binding potential among men ...
Defective sperm decondensation: A cause for fertilization failure
(2002)
The study aimed to evaluate the role of chromatin packaging (CMA3 staining), sperm morphology during sperm-zona binding, sperm decondensation and the presence of polar bodies in oocytes that failed in vitro fertilization ...
Wheat germ agglutinin receptors on human sperm membranes and sperm morphology
(1994)
Sperm membrane components play an important role in the determination of sperm fertilizing ability. During spermatogenesis, epididymal transit, and capacitation, the sperm membrane undergoes various subtle changes which ...
Normal sperm morphology and chromatin packaging: Comparison between aniline blue and chromomycin A3 staining
(1999)
The successful implementation of ICSI has provided a unique means of allowing couples suffering from severe male infertility to achieve their reproductive goals. However, despite the great therapeutic advantages of the ...
