Abstract
The success of assisted
reproductive technologies has been increasing since the birth of the first
test-tube baby. Nowadays, however, there are a number of factors that
remain to be clarified, such
as the influence of the integrity
of male gametes and females
in fertilization, the development of the embryo,
as well as the influence of controlled ovarian hyperstimulation, markers
of endometrial receptivity, uterine abnormalities and immunological factors that affect
genetic and molecular expression. A better understanding of these mechanisms will allow us to increase the
rate of implantation, clinical pregnancies, and births of healthy babies,
in patients subjected to assisted reproduction techniques. This
paper describes the factors involved of the mother or the embryo in the implantation failure and which
of these are seen
more frequently. There
are different factors
that favor the occurrence
of a failure in the implantation, some
articles mention that
it may be due to embryonic, uterine, or systemic
causes.
Biography
I am a
Mexican-Nigerian Biologist with 10 years of experience. I finished my degree in
Biology in 2010 since I have focused all my efforts on getting specialized in
Assisted Reproductive Technologies. In 2012, I completed a specialization
course in clinic embryology in Mexico, then in 2013, I improve my knowledge by
completing a master`s degree in Biotechnology of Human Assisted Reproduction
and Embryology at the University of Valencia Spain. My work involved carrying out
all procedures and IVF treatments for couples with fertility problems and
successfully achieved several pregnancies.
