In vitro fertilisation (IVF)

Why does embryonic arrest sometimes happen during in vitro development?

Many factors can intervene in arrest processes during embryo development which mean cell division is detained and, therefore, it is not possible to implant the embryo in the mother’s uterus and bring about a pregnancy.

In the first instance, the conditions for development are essential.  Embryos that develop in vitro are subjected to a number of artificial […]

Recommendations following embryo transfer

Transfer is undoubtedly one of the most important steps in assisted reproduction treatment.

When the patient steps out of the transfer room, a new beginning takes place and the experience will be totally different to what she has undergone up until that point. The embryos have now been transferred and the countdown to the pregnancy test has begun.

It’s […]

What are an embryo’s nutritional requirements prior to transfer to the mother?

During in vitro fertilisation processes, for the first few days of their lives, human embryos have to develop outside the mother’s body in special incubators.  Temperature and pH conditions need to be optimum and embryos also need to have access to all the necessary ingredients in order to feed and, in doing so, meet their […]

Ovarian stimulation: What is it? Are there any risks involved?

During the first few days of a period, a complex process takes place in the ovaries. The first step is to gather and initiate development in several follicles that contain eggs. Following this, only one egg is selected and it then develops. A mature egg is released during ovulation.

The advantages and disadvantages of transferring embryos during a natural or artificial cycle

Embryo transfer to the uterus is the pinnacle of all courses of assisted reproduction treatment. It cannot be left to chance. The endometrium needs to be receptive and facilitate embryo embedding.

The endometrium can be prepared with the aid of drugs (oestrogens) to simulate natural uterine behaviour – a substituted or artificial cycle – or transfer can be carried out […]

Assited Reproduction Techniques: FIV vs ICSI

Currently there are two main techniques used to achieve Assisted Reproduction IVF. These two techniques are conventional in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI).

In IVF, the previously capacitated male sperm are deposited together with the oocytes of women in fertilization medium in order to achieve fertilization as similar as possible to that […]

ICSI indications

Use of the intracytoplasmic spermatozoa injection (ICSI) technique began in the 1990s. It has been successfully used to resolve most severe cases of male sterility. Here is some information about when we use the ICSI technique:

When is ICSI (Intracytoplasmic Sperm Injection) indicated?

How to deal with the diagnosis of sterility due to unknown causes

Now what? Why can’t I get pregnant?

These are undoubtedly the first two questions that come to mind after being evaluated for a fertility problem and the doctor tells you that there’s no known cause that explains why you can’t get pregnant.

Nowadays, basic sterility studies are unable to detect the exact cause of over 25% of all cases, which doesn’t mean that it can’t be diagnosed with specific tests or that a case with an unknown cause can’t be properly treated.

The miracle of embryo implantation

Embryo implantation is the process in which the human embryo adheres to the endometrium, where it continues developing. The first step of this process begins with the dialogue between the embryonic and maternal cells.

This is an extremely complex process that is currently only partially known and depends on the embryo quality, uterine receptivity and their […]
