Discover in depth the biological processes related to fertilization, embryo implantation and all aspects affecting human reproductive biology.
In recent years, thanks to long culture and the use of time-lapse incubators, we have been able to preserve embryos in the in vitro fertilisation (IVF) laboratory until day 5-6 of embryo development. This has […]
The assisted reproduction in humans that we are familiar with today would not have been possible without the discoveries made over 70 years ago.
Specific management and quality control systems are key factors in increasing success rates at in vitro fertilisation laboratories (IVF laboratories). Since 2006, all Instituto Bernabeu clinics have adhered to official international ISO 9001 quality management […]
Now we are more than used to the word antibodies, and what they are for, which is to protect us against infections, could it be that there were antibodies capable of binding to their own […]
Primary ovarian failure (POF) or early menopause is the loss of ovarian function before the age of 40. As a result of this cessation of ovary function, the woman stops having menstruation and her hormonal […]
From the moment of fertilization, the embryo’s first divisions have been the oocyte responsibility, as the DNA and proteins synthesis took place before fertilization. Therefore, day 3 of embryo culture represents the end of a […]
What is the egg vitrification about? Vitrification technique is a relatively new freezing technique based on avoiding the ice crystals formation inside the cells when temperatures below 0 are reached (freezing), therefore, protecting them from […]
Spermatogenesis is the process of the sperm formation, which are male gametes. It takes place in the testicular seminiferous tubules with an approximate duration of 62 to 75 days in the human species. Sperm formation […]
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 […]
Ovarian drilling is treatment that is given to patients with polycystic ovary syndrome in order to encourage spontaneous ovulation. Polycystic ovary syndrome (PCOS) is a common disorder and the women who have it can have a […]
