Before the sperm of the male partner can fertilize the egg of his partner, the sperm’s head must attach to the outside of the egg. When it gets attached, the sperm pushes through the external layer to the inside of the egg, also known as cytoplasm, where fertilization happens. What happens sometimes is that the sperm can’t penetrate the outer layer.
The reason behind this thing can be different. There can be a condition where the outer layer of the egg may become rigid to go through or the sperm may be incapable to swim. Intracytoplasmic sperm injection is one of those Techniques Used for IVF in today’s world to assist the egg.
Intracytoplasmic sperm injection or ICSI stands for a similar procedure like conventional in-vitro fertilization where eggs and sperm are collected from the couple but one of the differences between them is the practice of obtaining fertilization. Intracytoplasmic sperm injection is a laboratory procedure-based technique in which a single sperm from the male partner gets picked up with the help of a fine glass needle and gets injected directly into an egg of female partner.
Basically, the Techniques for ICSI is divided into some steps. Firstly, the eggs are assessed for maturation through the removal of outer covering cells. It is then held with a dedicated pipette. After that, the doctor will introduce immobilized single sperm into the egg’s cytoplasm and carefully reverse the needle.
In the end, the eggs will be checked the following day for the proof of standard fertilization (appearance of 2 pronuclei). When fertilization is achieved it is followed by embryo development, then embryo assessment and the transfer to physically place the embryo in center the uterus. There might be a requirement of some blood test or ultrasound to check if implantation and pregnancy have achieved.
Who qualifies for ICSI
This kind of technique is most indicated in those couples with Male infertility. There can be different causes behind male infertility like poor motility, poor sperm quality, low sperm count, poor movement of the sperm, or sperm that lack the capability to go through the egg.
One or more conditions that can bring male infertility is azoospermia. This is a circumstance where no sperm is found in the man’s semen ejaculate. This could be obstructive and non-obstructive. The existence of obstructive azoospermia can happen due to some reasons like scarring from prior infections, congenital absence of the vas deference and prior vasectomy. When the defective testicle isn’t generating sperm, non-obstructive azoospermia happens.
The collection of sperm is firstly done through normal ejaculation. If the male partner contains a vasectomy, doctors can apply the microsurgical vasectomy reversal to restore fertility. One of the alternatives, when a capable microsurgical vasectomy reversal fails, is testicular or epididymal sperm aspiration.
The facility of needle aspiration permits the doctors to quickly and easily acquire sufficient numbers of sperm for the ICSI technique. Talking about needle aspiration, it refers to an easy process performed under sedation with minimum discomfort. Though there are chances of experiencing some pain and swelling afterward. But it resolved on its normally without complication.
Both the techniques of ICSI and IVF are helpful to those couples who find difficulties to conceive. Some conditions like low ovarian reserve will prompt the doctor to suggest having IVF using ICSI technique. Low ovarian reserve stands for a condition where a lower number of eggs get generated in the ovaries of a woman and there will be lesser chances of pregnancy. if the embryos are of lower quality and chances of successful implantation are grossly low.
The cost of the ICSI technique will depend on different kinds of factors like hospital amenities, several cycles implemented, the experience of the surgeon, the location of the hospital, etc. If someone is going to adopt the technique of ICSI, they need to make a balanced combination of diet and regular exercise must be present. Combating stress will be an option to prepare the body for the procedure. These kinds of treatment prove to be one of the major decisions of life, that’s why try to get proper information and consult the queries with the doctor.
