Evaluation of Different Culture Media for in Vitro Fertilization
A study testing culture media in people with Infertility, Female, run by Hospital de Clinicas de Porto Alegre at 1 site in Brazil.
Trial summary
Under in vivo conditions, human gametes and embryos are exposed to fluids in the fallopian tubes, where fertilization occurs, and in the uterus, the site of embryonic implantation. The composition of these microenvironments is extremely complex and diverse. Read more about this study

About this study
Official title: Evaluation of Different Culture Media for in Vitro Fertilization: a Randomized Clinical Trial
Under in vivo conditions, human gametes and embryos are exposed to fluids in the fallopian tubes, where fertilization occurs, and in the uterus, the site of embryonic implantation. The composition of these microenvironments is extremely complex and diverse. On the other hand, infertile couples who need in vitro fertilization treatments have their gametes and embryos cultured for a few days in commercial culture media. The composition of the media used in assisted reproduction laboratories varies according to the manufacturer and culture strategy. It is already known that the exposure of embryos to different concentrations of nutrients can affect the effectiveness of in vitro fertilization treatments, such as the fertilization rate, embryonic development speed, implantation rate, gestation, abortion, newborn weight, among other factors. Although these aspects are much discussed in the literature, there is still no consensus regarding the choice of a specific culture medium. Thus, the present study aims to evaluate the influence of three commercial culture media on the fertilization rate and embryonic quality through a prospective randomized clinical trial using sibling oocytes from patients undergoing in vitro fertilization cycles.
Read the detailed description
For this prospective randomized clinical trial, patients undergoing IVF cycles with at least three oocytes obtained from ovarian aspiration procedure will be enrolled. Considering a 30% difference between the groups in the number of good quality embryos (A + B) with power of 80% and p alpha 5%, the n calculated was 95 oocytes for each group, totaling 285 oocytes retrieved and 48 patients, as the mean number of oocytes per patient is 6.
The two main parameters that will be evaluated are:
Fertilization rate: An oocyte with 2 pronuclei and 2 polar bodies formed (2PN/2CPs) is considered fertilized. The evaluation of oocyte fertilization rates in three tested media will be measured by the percentage of 2PN/2CPs zygotes observed in the check between 16-18 hours after fertilization by IVF or ICSI.
Embryo quality: Embryos will be classified as A, B, C or D according to the scheme below, with A and B embryos being considered good quality embryos. The evaluation of embryonic quality will be carried out on the third day (64-67 hours after fertilization) taking into account the parameters of cell number, symmetry and fragmentation.
Embryo quality was defined as the primary outcome of this study because it is a parameter directly related to the prognosis of in vitro fertilization treatment, and it has a predefined value in the Vienna consensus being commonly described in scientific articles.
Fertilization rates and good quality embryos will be expressed as percentages (mean and standard deviation). The chi-square test will be used to compare fertilization and embryonic quality between the culture media and the difference will be considered significant if p < 0.05. For tabulation and statistical analysis, the JASP software version 0.16.2 will be used.
