Embryo fragmentation

Embryo fragmentation is a phenomenon that takes place in most embryos and its origin is not entirely clear. Some studies would seem to suggest that the fragments come from cell remains that have no nucleus or that they are the result of the decomposition of one or more cells from the embryo itself. The oocyte plays the most important role in fragmentation. Poor oocyte quality can lead to embryos that are highly fragmented. Embryo quality is determined by several characteristics such as the number of cells, their size or if the cell interior has an abnormality of any kind such as granularity or vacuolisation.

Types of embryo fragmentation

However, one of the factors that has most impact on embryo quality is the extent of fragmentation. Based on the amount, in percentage, of space that it occupies, fragmentation is categorised into 4 types or degrees.

A negative beta hCG test. Now what?

What happens following the wait (‘the beta hCG wait’) which generates so much anxiety whilst, at the same time, creating the hope that our lives may be changed forever when, in the end, the result is negative?

Many patients say that the absence of symptoms meant that they knew what was coming; Others were also expecting the worst because they had begun to bleed prior to getting the result of the analysis.

Presence or absence of pregnancy symptoms

It’s important to point out that the presence, or absence of ‘symptoms’ which women associate with pregnancy, are not a means of diagnosis. It’s also important to clarify that vaginal bleeding of varying intensity is not infrequent prior to the programmed pregnancy test date and this does not necessarily mean that the result will be negative. Indeed, the results obtained from an analysis of the pregnancy hormone in blood, is the only reliable proof available. A urine analysis is also an option, but needs to be carried out a little later on and is not one hundred percent reliable.

Blocked fallopian tube. The involvement of “tubal factor” in fertility

The Fallopian tubes are trumpet-shaped structures that begin in the uterine cavity and end up opening by the ovaries. After ovulation, the fallopian tubes collect the released egg that is fertilized on the first portion, which is the closest part to the ovary. For this, the spermatozoa travel through the vagina, the cervix, the uterine cavity, and finally the route to the end of the tube. After fertilization occurs, the embryo (fertilized egg) launches its first divisions and travels through the fallopian tube towards the uterus where implantation occur and thus the establishment of pregnancy.

What are the potential complications associated with IVF?

In vitro fertilisation is the most common form of reproductive medicine and, since the issues which need to be solved are often complex, it is not always possible to get the desired result.

Over the last few decades, the possible side effects or risks associated with  in vitro fertilisation (FIV) have gone down considerably.

Artificial ova and spermatozoa generated using stem cells

Research into and publications about the use of stem
cells to generate artificial gametes
cells has increased significantly over the last few years.

The idea of obtaining ova and spermatozoa – highly complex and specialist cells – using a cell obtained from an adult human being is both appealing and worrying. Patients who are unable to generate their […]

What is artificial insemination at home? What are the differences between artificial insemination at home and artificial insemination in a fertility clinic?

As a result of a number of television programmes, as well as articles in newspapers and online, it has now become public knowledge that what we commonly know as artificial insemination at home is becoming an increasingly common practice.

The term could well be labelled incorrect or even deceptive if we take into account that insemination at home could never be on an equal footing to the artificial insemination carried out in a health clinic that has the necessary authorisation to carry out assisted reproduction techniques. The differences between the two are significant.

Do ibuprofen and paracetamol affect fertility?

Pain killers, including paracetamol, and
non-steroidal anti-inflammatory drugs such as ibuprofen are the most
readily-available and commonly-used medicines in the world. This is because
they treat non-specific pain (migraines, high temperatures, muscular pain,
general discomfort, etc.) and because we, the general public, see them as
highly effective and accessible without a prescription.

A few years ago, use of these drugs, which […]

How do male and female contraceptives affect my fertility?

Contraceptives are any means of stopping the union between an ovum and a spermatozoon from taking place
and, therefore, avoiding pregnancy.

There are a number of available contraceptives  for men and for women and their impact on fertility varies.

So-called ‘natural’ contraceptives (the rhythm or Knaus-Ogino method, basal temperature or […]
