IUI (Intrauterine insemination)
This procedure is among the least invasive ART treatments. Sperm from the partner or a donor is introduced into the woman’s uterus, during a natural or induced cycle. The success rate is dependent on the woman’s age and is approximately 8-15%.
IVF (In vitro fertilisation)
IVF was developed over 30 years ago and is today the most common and effective type of fertility treatment. Hormones are given to the woman to stimulate the ovaries to produce excess follicles, where eggs develop. Approximately 9-14 days after stimulation has begun, an injection of hCG is given 36-40 hours before egg collection. Egg collection is performed under general anaesthetic and lasts approximately 10-15 minutes. Once the eggs are removed from the follicles, they are mixed with the sperm. The next morning the embryologists will assess the eggs for microscopic signs of fertilisation. A fertilised egg will divide and grow from one cell into 2, 4, 8 and more cells called an embryo. Viable, fertilised embryos are transferred to the uterus usually three or five days after egg collection. The remaining good quality embryos can be cryopreserved for future use. Approximately 14 days after the embryo transfer, a blood or urine pregnancy test is performed.
Egg freezing (Oocyte Vitrification)
Egg freezing is recommended for women under 35 years of age, but may be suitable for older patients depending on certain medical indications. Our Fertility Specialist would be able to advise you on whether this is appropriate for you.
We use the very latest vitrification techniques for cryopreservation of oocytes, a process which uses a much faster cooling rate to ensure optimal egg survival. The oocytes are stored for later use in a secure liquid nitrogen tank. Oocytes can be kept cryopreserved for 10 years in the first instance and up to 55 years in total in certain circumstances.
Egg freezing is available for:
- Women who want to postpone motherhood in order to avoid the effects of ageing eggs
- Cancer patients in order to preserve their fertility potential
- Woman undergoing IVF when there is a risk of OHSS, development of polyps, hydrosalpinx, absence of sperm, etc. in order to preserve the oocytes for future treatment cycles
Natural Cycles IVF
To discuss Natural Cycles IVF, please ring 020 8209 3226 or book your appointment. Thank you.
Natural Cycle IVF uses no drugs to stimulate growth of supernumerary follicles. Natural Cycle IVF follows natural selection of leading follicle.
This is its major difference from conventional IVF and why Natural Cycle IVF can be easier, less stressful, and much less expensive. With Natural Cycle IVF, your body naturally selects your best egg. When mature, usually around the tenth day of your cycle, the egg is retrieved during an egg collection. It is then fertilised with your partner’s (or donor’s) sperm.
If fertilisation and embryo development occurs, a single embryo is replaced in the uterus at the embryo transfer. Two weeks after that we test for pregnancy. The entire process is based on your menstrual cycle and takes 10-14 days. You will require no or minimal drugs, and almost no chance of multiple pregnancies all of which minimises stress. The cost is about 30% of conventional IVF.
