Ovarian tissue preservation |
In women whose ovarian function may be permanently compromised by pathologies or radio- and chemotherapy, portions of ovarian tissue can be surgically removed, cryopreserved for long periods and placed back in the ovary at a later time. The tissue thus reimplanted often guarantees a resumption of the ovarian cycle and sometimes the possibility of spontaneous conception. |
ICSI |
ICSI differs from IVF only in the way fertilization is achieved, which involves injecting a single sperm into each oocyte. This makes it possible to treat even the most severe cases of male infertility, using sperm present in the seminal fluid or surgically recovered from the testicle. |
IMSI |
Similar to ICSI, IMSI (Intracytoplasmic Morphologically selected Sperm Injection) consists of the microinjection of a single spermatozoon into the oocyte. However, the spermatozoon to be microinjected is selected according to more rigorous morphological criteria than in ICSI, using a device that allows observation of the male gamete at a magnification of 6600 times. In this way, characteristics of the spermatozoon head (such as shape, size and regularity) that are believed to be an expression of the male gametic quality can be evaluated much more precisely. Although not fully validated, IMSI emerges from numerous studies as a technique capable of increasing the chances of success for couples who have experienced repeated failures with the ICSI technique or for cases in which the quality of the semen sample is seriously compromised (oligo-astheno-teratozoospermia or high degree of fragmentation of the sperm DNA). |
Embryo culture to blastocyst stage |
Embryos are usually transferred into the uterus on the second or third day of development. Using specific culture techniques, embryos can develop for up to 5-6 days in an extracorporeal environment. This option is not always applicable, but in the most favorable cases it allows the identification of the embryos most suitable for transfer. |
Assisted hatching |
Embryos are usually transferred into the uterus on the second or third day of development. Using specific culture techniques, embryos can develop for up to 5-6 days in an extracorporeal environment. This option is not always applicable, but in the most favorable cases it allows the identification of the embryos most suitable for transfer. |
Semen cryopreservation |
Embryos are usually transferred into the uterus on the second or third day of development. Using specific culture techniques, embryos can develop for up to 5-6 days in an extracorporeal environment. This option is not always applicable, but in the most favorable cases it allows the identification of the embryos most suitable for transfer. |
Oocyte cryopreservation |
Oocytes can be cryopreserved, that is, kept at the temperature of liquid nitrogen (-196°C) for a long period and used at a later time. This allows for the valorization of any supernumerary oocytes or for intervention in cases of fertility preservation. |
Embryo cryopreservation |
In compliance with current laws and in the interest of women's health, in specific cases cryopreservation and deferred use of embryos in excess of the number required for a single transfer to the uterus is permitted. In this way, multiple pregnancies can be limited or eliminated without compromising the overall efficiency of the treatment. |
