Why IUI fails?? What is meant by timely death of a cell or programmed
cell death in time?? What is enhanced apoptosis: We know that RBC dies after
120 days. We also know that there are three indications where the opinion will
vary about the indication & decision to go ahead with IUI or with IVF procedure.
Many gynaecologits of modern era dissatisfied with the outcome of IUI in these
three following conditions will vote for IVF which is costly procedure and many
Indian couple can’t afford. However, apoptosis –i,.e,. Programmed cell death (death
of aged & poor quality cells of body anywhere in the body) is accelerated
in these three clinical entities.
What is apoptosis??
Ans;-Apoptosis is a natural helping mechanism to get rid of the damaged cells or
poor quality early embryo or any unwanted cells.. if extensive, could also lead to developmental
failure. In spite of this effective program, the ability of an early embryo to
undergo apoptosis appears to be developmentally regulated.,
Accelerated apoptosis
like hemolysis of foetal RBC in Rh immunized mother:-:-Such
abnormally high rate of cell death also affects the survival of eggs and sperms
(when pushed to uterus in IUI procedure.). These three following conditions where
apoptosis is accentuated leading to even death of a good quality ova, infused
sperm or fresh potentially good quality blastocyst or embryo are namely A) minimal endometriosis, B) Untreated or incompletely
treated Pelvic adhesive diseases & C) one sided tube block . Additionally some cases of unexplained
subfertility may have toxins which can yield to poor success of IUI!!! In these four
(including some cases of unexplained subfertility) clinical conditions where
there is preexistent enhanced apoptosis form a sizeable indications of IUI(some
call it poor couples IVF) & also a
common cause of failed IUI . As I said if one separates these three cases then
the success of IUI will speed up to 30-35% per cycle comparable to IVF. Let the
members be aware that in endometriosis the egg quality in most cycles are
persistently poor and in one sided tubal block, pelvic adhesive diseases , few
unexplained subfertility too some
organism still lie in tube and or endometrium.
