The Seminal Microbiome: How Bacteria Affect Fertility
A new study reveals that the bacteria present in the male reproductive tract, known as the seminal microbiome, play a key role in fertility. A healthy bacterial profile improves semen quality, whilst an imbalance can have a negative impact on assisted reproduction.

Platelet-Rich Plasma (PRP) improves success in assisted reproduction
A recent study confirms that the use of platelet-rich plasma (PRP) in assisted reproductive technology treatments significantly improves implantation rates, clinical pregnancy rates, and live birth rates. Learn more about this regenerative technique and how it benefits women with a history of implantation failure.

What are the requirements for intrauterine artificial insemination?
The requirements for intrauterine artificial insemination (AI), with either partner or donor sperm, are patency of the fallopian tubes, good ovarian reserve, and sperm quality of 3 million or more motile spermatozoa in the REM seminogram.

Can pregnancy be achieved with testicular varicocele?
Varicocele or inflammation of the veins of the spermatic cord is one of the main causes of male infertility. Therefore, men with varicocele may have difficulty in achieving pregnancy. As a first therapeutic option, surgery is recommended, since it is close to 90% effective.

How to improve implantation rates in Assisted Reproduction?
Embryo implantation is an essential process for gestation to occur. It is the adhesion of the embryo to the uterine endometrium of the woman. For implantation to take place, the embryo and the endometrium must be in the right conditions and, in addition, there must be synchrony between them.

What differs in pregnancy with fraternal twins or identical twins?
Multiple pregnancies occur when more than one baby develops in the maternal uterus. The most common are fraternal or identical twins. Assisted reproductive techniques have increased the birth rate twins, although nowadays this trend is being limited due to the risks involved in multiple pregnancies, and improved AR techniques

Frozen vs. fresh embryos: impact on fetal growth
New research analyzes early intrauterine growth by comparing IVF cycles with fresh and frozen embryos. The results show a slight difference in size in favor of frozen embryos, regardless of whether they are blastocysts or day 3 embryos.

Double donor IVF: assisted reproduction with donor egg and sperm
IVF with egg and sperm donation is a fertility treatment in which the woman or couple needs to resort to donor gametes in order to have a child. The benefits of double gamete donation are the high success rates in people with severe fertility problems.

Endometrial receptivity and implantation failure
International researchers confirm that women with implantation failure suffer more alterations in their implantation window. The study highlights that advanced age and a long history of infertility are determining factors for indicating personalized endometrial receptivity tests.
