What can we see in ultrasound scans: follicles or oocytes?
Artificial insemination, Assisted reproduction, Fertility, Gynaecology, Implantation failure and recurrent miscarriage, In vitro fertilisation (IVF), News, Poor Ovarian Response Unit, Pregnancy, Reproductive biology, Women’s healthMistaking ovarian follicles for oocytes is one of the most common errors made by patients.
During ovarian stimulation, whether this is for regulating ovulation for insemination or for in vitro fertilisation, patients are administered different types of medicines depending on each case. However, there is one common aim: predicting and causing ovulation. This can be just once for patients attempting managed sexual intercourse and […]
What is vaginal
flora?
A number of microorganisms consisting of bacteria, viruses and fungi co-habit in the vagina meaning that this area of the body is not sterile. These microorganisms are what are known as vaginal flora. They are essential for balancing our organism’s homeostasis and they protect us from other microorganisms that could cause illnesses.
Lactobacillus is the […]
Just like with any specialist area of medicine, when we need to turn to a reproductive medicine clinic, we have a number of concerns and we need to have a clear understanding of what our needs are and what we expect from an assisted reproduction clinic. It is very important to choose carefully because they […]
I’m not very old but I’m not young enough to just let time go by. I’ve been thinking about this for a long time now. I’ve always wanted to have children. It’s not something I feel I can’t live without but it is something I’d like to do. I’ve been in several relationships but none […]
The miracle of conception involves an intimate union between the ova and spermatozoon, appropriate evolution of the fertilised embryo and, furthermore, an ideal environment inside the uterus so that implantation can take place. Whilst this process might seem simple, it is much more complex than we might think, particularly in human beings. Only 30% of our conceptions end in […]

The ‘implantation window’ is the name we give to the period of time during which the endometrium in the mother’s uterus is in an appropriate state for embryo implantation to take place.
Implantation is a critical and very precise process during which the embryo makes contact with and penetrates the endometrial tissue in the mother, making gestation possible. This […]
After ovulation, follicles transform into the corpus luteum or ‘yellow body’. Corpus luteum development depends on the luteinising hormone (LH) surge before ovulation and on the number of receptors for this gonadotropin in the granulosa cells and in the theca cells. Both types of cells go through significant changes in structure and composition and this turns the walls of the corpus […]
Whilst it is not part of the day-to-day routine at reproductive
medicine clinics, it is now increasingly common to have to transport biological
samples (oocytes, semen or embryos) from one clinic to another and even from
one country to another.
There can be several reasons for this such as the following:
– The
couple wishes to continue their treatment in a […]
Personalising courses of treatment is undoubtedly currently the
most important area of change in the field of medicine. A specific strategy should be designed
depending on each patient’s individual characteristics.
One of the key areas for developing personalised medical healthcare is the use of pharmacogenetics. A patient needs different doses or types of pharmaceutical drugs depending on certain genetic variations. […]
