Abstract
ICSI is now one of the most successful and viable techniques in
assisted fertilization and revolutionized the treatment of male infertility. In
those who have no identifiable or correctable cause, ICSI provides new hope
for couple with male infertility.(Infertility is common and the global burden
remains high over the years and it is used to overcome female or male
fertility problems) (16).
PPR has aroused interest as some authors have suggested decreased
CPR with this phenomenon. The debate whether this subtle PPR negatively
affects ICSI cycle outcome is still ongoing. The issue isn’t new but still
unresolved, Schoolcraft et al, had 1st reported in 1991, that CPR is
adversely affected by PPR.(92),4)
In 1991, Schoolcraft et al & Silverberg et al. mentioned that a
modest PPR was associated with lower PR and higher rate of AB in COS
for ICSI, but the pathogenesis & effects remain controversial.(4, 6)
Most studies used an absolute P-hCG as an indicator of PL, and the
cut-off value differed (0.8 to 2 ng/mI). The threshold level for premature
increase in serum P-hCG was arbitrarily defined within various
studies.(166)
The aim of study to study the P4-Hcg level effect on ICSI outcome
including; the number of OR, oocyte quality, number & quality of ET and
pregnancy outcome.
