Assisted reproduction is a field in which advances and improvements are continually achieved in both the techniques used and knowledge of the aspects involved in achieving a pregnancy. FIVValencia is aware of this and offers the best techniques available, each of which is indicated to resolve the situation for each unique couple.
ARTIFICIAL INSEMINATION
This involves selecting the best mobile spermatozoon and stimulating their ability to fertilise (capacitation), to later deposit them in the uterine cavity.
Semen from the spouse (IAC) may be used, or semen from a donor (IAD) in cases of azoospermic, hereditary illnesses or for women without partners.
Our results:
|
IAC
|
|
15% pregnancy in one cycle.
55% pregnancy in four to six cycles.

|
|
IAD
|
|
27% pregnancy in one cycle.
80% pregnancy in four to six cycles.

IN-VITRO FERTILISATION
This technique is used to fertilise the woman's ova with the male spermatozoon, in the laboratory and in conditions that are similar to natural conditions.
The phases are: Ovarian stimulation, ova extraction, fertilisation in the laboratory, “in-vitro” embryo cultivation and transfer to the maternal uterus.
Our results:
55% pregnancy in one cycle.
90% pregnancy in three cycles.
SPERMATOZOON INTRACYTOPLASMIC MICRO-INJECTION
SIMI is a special ova insemination technique developed for cases where there is a low concentration of spermatozoon.
In these cases, a single spermatozoon is selected to insert into the ovum.
The results are similar to conventional IVF (55%).
Thanks to SIMI, many couple actually achieve pregnancy with this technique instead of opting for donor semen.
EMBRYONIC TRANSFER
This involves placing the embryos obtained into the woman's uterus using a special cannula tube.
FIVValencia usually transfers two embryos, although every day more transfers are being made with just one embryo in young couples with good prognostics and for those who want a second child.
EMBRYONIC CULTIVATION
The embryos remain in cultivation in the laboratory for five to six days until they reach the “blastocysts” stage.
The blastocyst is the embryonic stage with the greatest potential for implantation and pregnancy and enables a pregnancy rate of up to 65% to be achieved in each cycle.
“ASSISTED HATCHING”
This involves making a small opening in the embryonic membrane to facilitate its implantation into the maternal uterus.
It is indicated for patients with advanced age or with repeated IVF implantation failures.
VITRIFICATION
The good quality embryos that are not transferred to the uterus are frozen with a vitrification procedure that enables embryos to be preserved for future use.
PRE-IMPLANTATION GENETIC DIAGNOSTIC (PGD)
This is a very early method for embryo genetic diagnosis. Embryos without chromosome or genetic alterations are identified and transferred to the maternal uterus in order to obtain a healthy baby.
SEMEN BANK
In cases where it is not viable to use the partner's semen, the alternative is to use donations from young donors to provide a very successful method of achieving pregnancy.
