Male fertility problems are most common than people think. Although there are many conditions that can cause infertility, in approximately 50% of all men with this condition, the cause cannot be determined.
Among the most common causes of male infertility hormonal imbalances and abnormalities (such as blockages) in the reproductive organs can be included. Likewise, it is considered that approximately 10 or 15% of infertile men have a complete lack of sperm.
Fortunately, there are many assisted reproduction techniques that help to achieve pregnancy even in the worse scenarios nowadays.
In a sperm test, one of the most important characteristics to evaluate is the spermatozoa motility or movement capacity. To consider a normal motility, the spermatozoa must have at least 50% of forward progression and the presence of at least 20 motile sperm per each cc (cubic centimeter).
On the other hand, the World Health Organization (WHO) classifies the spermatozoa motility in grades (from a to d) according to the velocity which the spermatozoa swim forward. The grade “d” corresponds to sperms that do not move at all (immotile).
The intracytoplasmic sperm injection (ICSI) can be defined as an assisted reproductive technique used to facilitate the fertilization properly said during an in vitro fertilization (IVF) procedure (please follow the link to read more on In vitro fertilization IVF).
The ICSI consists on injecting a single sperm, previously studied and selected, in a mature oocyte (ovum) to simulate the natural fertilization process.
There is a very important relation between absolutely immotile spermatozoa and intracytoplasmic sperm injection because this assisted reproductive technique allows to fertilize an oocyte even when the spermatozoa has no motility at all.
It is possible because, as it was said before, during the ICSI procedure the spermatozoa is directly injected in the ovum, so as long as it is a healthy sperm, the ability to move by itself is not required.
The difference between in vitro fertilization and intracytoplasmic sperm injection is that the first one refers to the entire assisted reproductive technique that involves the extraction of the oocyte from the female ovary, its artificial fertilization and later, its introduction into the uterus when it is an embryo.
Conversely, the intracytoplasmic sperm injection is one of the techniques used to produce the artificial oocyte fertilization during an assisted reproductive procedure, especially, the in vitro fertilization.
As other reproduction assisted procedures, the intracytoplasmic sperm injection has a percentage of success that usually increases with each cycle of treatment. In fact, some studies show that although the rate of pregnancies in the first attempt of ICSI is 0, in the subsequent cycles (especially third and fourth) 51.7% of the couples achieved a successful pregnancy when using an immotile spermatozoa.
The cost of an intracytoplasmic sperm injection may widely vary among patients. Likewise, finding a good fertility specialist or center in your city may be difficult. So, if you think that intracytoplasmic sperm injection may be a good option to treat your infertility problems please contact us at contact@123.clinic and ask all your questions.
