This is a brief description of the service ...
 | The Fertilization in Vitro consists of reproducing the process of
fertilization that is produced in a natural way, but this time in the
laboratory, in which we need to have in the laboratory the eggs and the
sperms. Carrying out a cycle of stimulation of the ovaries with the purpose to
obtain numerous eggs and to guarantee a good embryonic transfer and even to be
able to freeze surplus embryos, to transfer in other subsequent cycles if did
not remain pregnant in the first one, or if the patients want to keep it for a
second pregnancy. |
| The retrieval procedure to obtain the eggs is performed transvaginally
using a hollow needle guided by the ultrasound image (this is completely
comfortable under adequate sedation and local anesthesia). Eggs are gently
removed from the ovaries using the needle. This is called "follicular
aspiration." Its timing is crucial because the egg will not develop properly
if it is collected too early; if too late, the egg also may develop poorly or
may have already been released from the ovary and lost. |
| There are two techniques: the conventional IVF and the Intracytoplasmic
sperm injection (ICSI), which is a procedure where a single sperm is selected
and delivered directly into a woman's egg. ICSI is an effective option for men
with low sperm count or sperm that cannot reach the egg successfully. |
