An increasing number of couples have issues having a child naturally. It is currently estimated that in 50% of all cases, the reason for infertility is poor semen quality.
The causes can be immunological, genetic or anatomical factors but there are also external factors that we can, to some extent, control. Highlighting the main common reasons for poor semen […]
Human beings have 46 chromosomes (23 pairs) and these chromosomes contain all the genes in the genome. Half of the 46 chromosomes come from our father and the other half come from our mother. Right from the embryo stage, humans need the number of chromosomes to be normal in order for them to develop correctly. If […]
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 […]
The World Health Organization (WHO) indicates that a man has hypospermia when the semen sample he produces when he ejaculates is below 1.5 mL. A semen analysis needs to be performed in order to obtain a diagnosis. This test measures different semen parameters such as the volume of the ejaculate, the number of spermatozoa, sperm mobility and so on.
In order […]
Artificial insemination (AI) consists of depositing semen inside the female genitals. A woman’s partner’s semen can be used if he does not have any serious male fertility issues but, nowadays, inseminations are mainly carried out using semen from a sperm bank.
What does
artificial insemination entail?
Insemination requires a strict control of when ovulation takes place. It is […]
Ejaculation is the organic process that controls the
discharge of semen from the seminal vesicles to outside the body. Substances of
nutritional and maintenance value are added along the route in order to
guarantee vitality and comfort as the spermatozoon travels on its journey to
outside the body. This journey can be
affected in a number of ways, particularly in […]
Implantation failure, defined as recurrent embryo transfer failures, remains a mystery because its cause is not always clear. The contractions that take place in the uterus could be one possible explanation for it.
The uterus is a muscle and, as such, it contracts. The intensity and direction of the contractions change throughout the menstrual cycle. Over the first few days, […]
From the moment embryo transfer takes place up until the day when a woman takes a pregnancy test, a set of events aimed at achieving implantation (adherence of the embryo to the uterus) take place in the uterus and embryo. The process has traditionally been described as a dialogue and this is, indeed, a good way of explaining […]
The human genome is composed of 20,000 genes. Genes contain information for synthesising all the proteins in our bodies and these proteins carry out various biological functions. The information is contained in regions called exons and they are separated by regions called introns that do not contain any information. The complete set of exons in our genome […]
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 […]
