Methods used vary, and it is useful to discuss with professionals which method suits you. For example, prolonged cultivation is a favorite topic for patients from countries where the method is less used, as is blastocyst culture not being the “secret recipe” of success. It is always up to each individual to weigh what makes sense.
It is also important to distinguish between methods that are subject to a charge and those that are free. For example, in our view, a clinic must not raise costs for ICSI because it is, after all, a task of the laboratory to fertilize as many oocytes as possible. However, IMSI may bring additional costs because of the relatively higher expenses to be paid by the clinic.
Here, we explain some common laboratory techniques:
Intracytoplasmic sperm injection (ICSI)
Intracytoplasmic sperm injection (ICSI) is the technique of injecting a single sperm in the oocyte. This method was initially developed in order to increase the chances in cases of poor sperm quality or of sperm retrieved by surgery. However, due to high success rates—on average, seven out of 10 oocytes are fertilized with the ICSI method—it recently became a standard.
The ICSI method does not harm the embryo; at least, there is no study proving it. Moreover, no evidence indicates higher risks after birth using the ICSI Method.
