Hepatitis is severe or chronic inflammation of the liver.
There are several possible causes including infections (viral, bacterial or parasitic).
The most common cause is a viral infection and, within these, hepatitis B (HBV) and hepatitis C (HCV) viruses are of particular relevance. It is possible to get infected as a result of contact in blood and contaminated objects (unsterilised surgical material, syringes or needles), due to sexual transmission through mucous membranes and so-called vertical transmission (transmission from mother to child, particularly during childbirth). The chances of this type of transmission are the same in both vaginal and caesarean births. […]

At Instituto Bernabeu, we are bidding farewell to ovarian stimulation injections during courses of in vitro fertilisation (IVF) treatment. The clinic is launching an innovative device called i-Port Advance™ for self-administration of drugs using a system that is already used by diabetics and which is being put to gynaecological use. By using this device, Instituto Bernabeu is revolutionising the future […]
These are just some of the questions that couples might ask at an important time during their treatment, just before embryo transfer.
In all cases of fertility treatment involving the in vitro fertilisation (IVF) laboratory, it is essential that all couples are given extensive, detailed and personalised information. This means talking about the embryo fertilisation and development processes.
When only a few fertilised oocytes are available as a result of poor ovarian reserve, transfer is carried out on day 2 or 3 of development in around 60% of cases because at this stage we can clearly select the embryos that are suitable for transfer. In around half of these cases it is not possible to cryopreserve embryos for future attempts. […]
1.- Ovarian stimulation in the patient is carried out by administering doses of hormones that stimulate ovarian function with the aim of achieving sufficient oocytes. The doses of the aforementioned hormones are personalised to each patient depending on her ovarian reserve and based on the results of antimullerian hormone levels in a blood test and a follicle count for each ovary using a vaginal ultrasound scan. Controlling each patient’s ovarian response is done over a series of vaginal ultrasound scans (an average of 3) and, in some cases, by checking oestradiol (the hormone produced by the ovary) levels in blood. Once the checks indicate that the ovary is ready, oocyte retrieval is scheduled. This period of ovarian stimulation lasts between 8 and 10 days in most women and does not affect the patient’s daily routine. […]
Significant progress has been made over the last few decades in the field of fertility in order for patients to be able to have children of their own. However, one of the greatest challenges in reproductive medicine is pregnancy in women with slim chances of obtaining their own eggs. For example, women with premature ovarian failure (in other words, egg loss at a young age) or, quite simple, women over the age of 40.
Over the last few years, progress in terms of freezing both embryos and oocytes has meant that embryo transfer can successfully be carried out during a cycle that does not need to be the ovarian stimulation cycle itself.
Such progress has led to new forms of ovarian stimulation that concentrate exclusively on retrieving an adequate number […]
Having a sufficient number of mature egg cells is one of the key steps to obtaining excellent results in a cycle of in vitro fertilisation (IVF). In order to achieve this, the ovaries need to be stimulated and, contrary to what happens during a natural cycle, the ovaries need to simultaneously mature an appropriate number of eggs.
The most commonly used stimulation protocols are based on the use of doses of follicle-stimulating hormone (FSH). These may or may not be administered along with other drugs and vary between 150 and 300 IU/day. The response will be somewhere between 7 and 15 follicles. […]
Behind our on-line consultation system, there is a team of trained personnel. The team is ready to help users and make them see that the concerns amongst people who are looking for an answer to their doubts or worries, are also our concerns. Instituto Bernabeu has a Personalised Counselling Unit. Its team of experts has been trained to clear up the doubts which people understandably have when they are thinking about beginning treatment, when they wish to compare opinions, when they are looking for help regarding how much treatment will cost or when they have gynaecological-related doubts about assisted reproduction. […]
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: […]
Follicle-stimulating hormone (FSH) is produced by the pituitary gland situated at the base of the brain. It is released from this gland into the bloodstream and plays an essential role with regards to the ovaries. Its purpose is to stimulate follicle growth and selection and it also plays a role in maturing the egg which will later be released during ovulation.
In cases of ovarian insufficiency, the pituitary gland attempts to compensate for this by increasing FSH secretion. This happens in a physiological manner during the menopause and, as a result, women going through this stage have FSH levels which are far above those in women of childbearing age.
If abnormally high levels of FSH (>10 lU/L) are detected at a young age, this can be a suggestion of low ovarian reserve which reduces the possibility of getting pregnant naturally. […]
