The interaction between human spermatozoa and its homologous zona pellucida : scientific advances and clinical significance
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Infertility is a very common problem worldwide. Recent data have shown that disorders of the
male represent the most common single defined cause of infertility. This proposal examines
the clinical ...
Evaluation of gamete dysfunction as a cause of failed human in vitro fertilization
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: Chapter 1 provides literature based background information on the clinical
importance of sperm morphology as recorded by strict criteria during the
diagnostic approach of the infertile couple. Furthermore, ...
Acrosome size and kinematics of human spermatozoa
(Stellenbosch : University of Stellenbosch, 2007-03)
For spermatozoa to gain access to the oocyte for fertilization, lytic enzymes need to
be released during the acrosome reaction. These enzymes, which are stored and
transported within an organelle termed the acrosome, ...
A study of the intracellular signalling events involved in the zona pellucida-induced acrosome reaction in human spermatozoa
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: In this study the author presents new data that will shed light on the fairly nebulous
knowledge of intracellular pathways involved in the physiologically induced acrosome
reaction and the subsequent ...
