The outcome of intra-cytoplasmic sperm injection (ICSI): do the sperm concentration and motility matter?

Intracytoplasmic sperm injection (ICSI).

Intracytoplasmic sperm injection (ICSI)

IVF has become a well-established treatment for certain types of infertility, including long-standing infertility due to tubal disease, endometriosis, unexplained infertility or infertility involving a male factor. Soon it became clear that certain couples with severe male-factor infertility could not be helped by conventional IVF. Extremely low sperm counts, impaired motility and/or abnormal m...

Special applications of intracytoplasmic sperm injection: the influence of sperm count, motility, morphology, source and sperm antibody on the outcome of ICSI.

The relationship between the three basic parameters of ejaculated spermatozoa, i.e. concentration, motility and morphology, and the results of intracytoplasmic sperm injection (ICSI) were investigated in 838 microinjection cycles. A further 123 ICSI treatment cycles in which testicular spermatozoa were used for microinjection were also evaluated. The influence of anti-sperm antibodies (ASA) on ...

Could using the zona pellucida bound sperm for intracytoplasmic sperm injection (ICSI) enhance the outcome of ICSI?

I n the recent literature, several interesting articles have been published using the zona pellucdia (ZP)-bound sperm for intracytoplasmic sperm injection (ICSI) to enhance embryo quality, implantation and clinical pregnancy rates. The three studies were performed independently in different ART clinics. In the test group, patients’ sibling immature (either germinal vesicle (GV) or metaphase I) ...

Human sperm centrin levels & outcome of intracytoplasmic sperm injection (ICSI)--a pilot study.

BACKGROUND & OBJECTIVE The objective of the present study was to compare the levels of sperm centrin a centrosomal protein that influences cell migration, in normal fertile donors and in oligoasthenozoospermic males (count 5 million/ml and motility <40%, grade c+d) undergoing intracytoplasmic sperm injection (ICSI) and to correlate with the outcome of ICSI. METHODS The prospective study carri...
