When can I find out how many of my ova have fertilised?

Ova and spermatozoa are needed in order to be able to perform in vitro fertilisation treatment. They are taken to the in vitro fertilisation laboratory so that, once they have been appropriately prepared, they can be joined together and fertilise.

Unfortunately, biology is not an exact science and the uniting a spermatozoon and an ovum does not always create an […]

Embryonic development: the embryo on day 1 (D1)

When an oocyte is in an optimum state of maturation, ovulation takes place. This is known as day 0 of development (D0) and fertilisation by a competent spermatozoon must take place during this period.

When the oocyte is fertilised, it is then known as a zygote and
we are now on D1 of development. Certain characteristics and essential
structures need […]

Will my frozen embryos survive?

Cryopreservation, or embryo freezing, is an essential part of courses of assisted reproduction treatment since it means that embryos can be preserved in order to be used at a later date and without the passing of time having a negative impact on their viability.
Embryos obtained as a result of in vitro fertilisation (IVF) may be thawed for a number of reasons: […]

Normal and abnormal embryo division

For as long as we can remember, we assume that we belong to certain standards. These standards are set based on the average population, just as children in pediatric check-ups are assessed by a percentile of height and weight. As adults we are assessed by our body mass index. In both cases, we try to reach an “average” rate.
What do we consider average?
This also happens at the embryonic stage. The process of embryo division observation is established to assess whether or not embryos are normal. This observation should be performed at specific times, so that each embryo is observed and evaluated daily.
