Surrogate Pregnancy after transfer of Cryoshipped, Vitrified Human Blastocysts

Rotunda achieved its first pregnancy with Cryoshipped Vitrified embryos from USA and transferring them into a surrogate mother.
Till now, we have received frozen embryos from many countries and successfully transferred them into surrogate mothers at Rotunda. Most of these embryos were frozen by the slow freezing process. As vitrification is becoming popular as a method [...]

Vitrified Embryos Seem To Produce Healthier IVF Babies

Three new studies have provided further evidence that vitrified embryos may be better than fresh for IVF. The studies were presented at the American Society for Reproductive Medicine conference in San Francisco, US, last week. The studies indicate that using vitrified embryos rather than fresh embryos reduces the risk of stillbirth and premature delivery. The technique allows more embryos to [...]

Freezing improves DNA integrity

Gamete cryopreservation could help improve the fertility of men whose spermatozoa show a high level of prefreeze DNA fragmentation, study findings indicate.
 Laura Thomson (Fertility First, Hurstville, Australia) and co-authors note potential cryoinjury of sperm from subfertile men is an issue of primary concern “considering that subfertile men form a very large proportion of the men [...]

Breast cancer recurrence not increased with controlled ovarian stimulation

Ovarian stimulation using gonadotropins and letrozole to preserve fertility in patients with breast cancer undergoing chemotherapy is unlikely to increase their risk for recurrence, say US researchers.
Kutluk Oktay, from the Center for Human Reproduction in New York, and colleagues evaluated 215 women with breast cancer for fertility preservation before adjuvant chemotherapy. Overall, 79 of the [...]

The Frozen Embryo Transfer

Frozen Embryo Transfer (FET)
If you have recently gone through infertility treatments or if you are considering undertaking IVF, you may be wondering what will happen to any extra embryos that are created during the procedure. If you and your partner have extra embryos that are not used during initial IVF procedures, these embryos can be [...]

Intracytoplasmic sperm injection (ICSI)

Intracytoplasmic sperm injection (ICSI) is an in vitro fertilization procedure in which a single sperm is injected directly into an egg; this procedure is most commonly used to overcome male infertility problems. With conventional IVF, one can expect approximately 75% of the oocytes (eggs) to fertilize if they are healthy and the sperm parameters are [...]

Embryo Grading

One of the trickiest jobs facing a clinical embryologist is the visual assessment of human embryos. Embryo selection prior to embryo transfer clearly has an enormous impact on the success of the treatment and embryo selection for cryopreservation is equally important to the future success of frozen embryo transfers.
 Patients are often awestruck when they [...]

Twins Born 16 Years Apart

UK newspapers have reported on the story of ‘twin’ girls born 16 years apart following IVF treatment. Jane and Alan Davis began IVF treatment in March 1989. Thirty-three eggs were collected, and fertilised with Mr Davis’ sperm, producing a number of viable embryos. Three were implanted and 22 others were kept in frozen storage to [...]
