Ovodonation
Anonymous egg donation is the most effective assisted reproduction technique, for it achieves the best pregnancy rates.
This technique uses anonymously donated eggs to be fertilised by sperm in the laboratory. The embryos resulting from the insemination are transferred to the mother’s uterus to promote implantation and establish gestation.
Each patient is unique. At VITA we design an oocyte donation treatment tailored to the patient’s needs.
Ovodonation with the partner’s sperm
Ovodonation with the partner’s sperm is a type of in vitro fertilisation indicated for couples where the woman cannot use her own eggs because they are of poor quality, are carriers of hereditary diseases or have ovarian failure due to menopause, early ovarian failure or ovarian surgery, making it necessary to resort to eggs donated by an anonymous woman
Ovodonation with sperm donor
Ovodonation with the partner’s sperm is a type of in vitro fertilisation treatment indicated for couples where the woman cannot use her own eggs and the man has a fertility problem related to poor sperm quality, is a carrier of a genetic disease, or for women without a male partner or same-sex couples
IVF with conventional egg donation or ICSI?
In conventional ovodonation, the capacitated sperm are placed in contact with the retrieved eggs in a laboratory dish, waiting for one of them to fertilise the egg in an autonomous and natural way.
But habitually ovodonation with ICSI (Intra Cytoplasmic Sperm Injection), a laboratory technique that consists of introducing a single selected spermatozoon into an egg to facilitate fertilisation, is usually used. This technique has been a great advance in the treatment of male sterility problems. A single spermatozoon is required per egg, selected mainly for its morphological characteristics, although in some cases methods such as MACS (Magnetic-Activated Cell Sorting) can be used, which allows eliminating from the ejaculate those spermatozoa that are destined to die and could not fertilise the egg.
