Brief Summary:
In a conventional in vitro fertilization (IVF) cycle, daily microscopic observation of embryos outside the incubator to assess their morphology and establish a selection process is performed. In this way it is possible to know which embryo or embryos have greater implantantion capacity and will be transferred to the uterus to obtain a viable pregnancy. However, these observations can produce deleterious effects on embryo development due to changes in temperature, pH and osmolarity of the culture media, as well as a negative effect of direct light microscope for observation. This project aims to test the hypothesis that non-embryonic observation produces a beneficial effect on embryo quality until day 5 of development (blastocyst stage) and, therefore, on rates of implantation and ongoing gestation, compared with the conventional protocol of observations under the inverted microscope on days two, three and five of development.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 130 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Care Provider)
Official Title: Prospective Randomized Study to Evaluate the Effect of Embryonic Observation on the Implantation Rates and Ongoing Gestation
Study Start Date : February 2014
Estimated Primary Completion Date : December 2016
Estimated Study Completion Date : June 2017

Arm Intervention/treatment
No Intervention: No embryo observation (NEO)
Study group. No embryonic observation from day one to day five of embryo development.
Experimental: Embryo observation (EO)
Control group. Conventional embryonic observations performed in day two, three and five of embryo development.
Other: Embryo observation
In EO group, conventional observations will be made.

Primary Outcome Measures :
  1. Ongoing pregnancy [ Time Frame: Ongoing pregnancy until 28th week of gestation ]
    Rate of ongoing gestation considered a positive pregnancy to display normal heartbeat and ultrasound markers until the 28th week of gestation

Secondary Outcome Measures :
  1. Ongoing implantation [ Time Frame: 12th week of gestation ]
    number of implanted embryos with heartbeat presence divided by the total number of embryos transferred, multiplied by 100.
