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 […]
What can I do to get that positive result? How can I help my in vitro fertilisation (IVF) treatment to work? Numerous factors have an impact on the success of in vitro fertilisation and getting pregnant. Living a healthy lifestyle, avoiding toxic habits, using medication appropriately and the following these 10 recommendations and pieces of advice, such as avoiding the use of perfume or ensuring that your bladder is full on the transfer day, may be a great help.

The term polycystic ovary syndrome is used to define an ultrasound diagnosis characterised by the presence of 12 or more follicles in each ovary (between 2 and 9 mm in diameter) and/or an incremented ovary volume (>10 ml). Findings such as these in ultrasounds in a single ovary are sufficient in order to be able to give a diagnosis. However, since taking oral contraceptives can change ovary morphology, this diagnostic criteria does not apply to women who take oral contraceptives.
From a practical point of view, when assisted reproduction technology (ART) is being used, detection of polycystic ovaries in isolation is useful for predicting the ovary’s response to stimulation using drugs and the risk of ovarian hyperstimulation syndrome. […]
Hormones are messengers that are present in all multicellular organisms – be they animal or plant organisms – that coordinate the functions of each part of that organism.
The sex hormones par excellence are oestradiol in females and testosterone in males. However, the adrenal glands in men and women produce both hormones and they are both necessary for normal development of the two sexes. […]
Oocyte quality is one of the most important of the factors that have an impact on fertility in women. Optimum oocyte quality generally gives rise to embryos with an increased ability to implant in the uterus. […]
Sexually transmitted disease (STDs) are infections that are transmitted, on the whole, during unprotected sexual intercourse. However, they can also be transferred from mother to child during pregnancy.
Acupuncture is a medical discipline with a history dating back several millenniums. For many years, attempts have been made to apply its therapeutic benefits to the field of sterility.
The results obtained to date have been contradictory. Whilst some groups have published improvements in the results obtained, others have not noted any differences at all. […]
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. […]
Cholesterol plays an essential role in ensuring that our organism works correctly. Its impact on the heart is still given priority in terms of analysis because of the elevated impact and frequency of diseases of this kind.
Whilst all the other areas of influence have been analysed to a much lesser degree, in some cases such as infertility, the effects of this essential component are now starting to come to light.
What is the importance of cholesterol in fertility? […]
