After your fertility assessment has been completed you will be given the chance to discuss a care plan with obstetrician and gynaecologist Mr Colin Davis. If invitro-fertilization has been indicated as your best option, there are several types of IVF:
Stimulated IVF – Stimulated IVF is the most established form of IVF and uses a variety of hormone based medication to over-ride the natural menstrual cycle so that fertility specialists can retrieve larger numbers of eggs to maximise the chances of conception. Drugs used could be:
Clomifene Citrate (Clomid) – This stimulates ovulation by encouraging the ovaries to produce more eggs.
Follicle Stimulating Hormone (FSH), Gonal F and Luteinizing Hormone – These hormones, given by injection, stimulate the ovaries to produce eggs. These may be used if the patient hasn’t responded to Clomid.
Human chorionic gonadotrophin (HCG) – This is the pregnancy hormone. This is produced by cells that form the placenta. Its function is to tell the corpus luteum to produce progesterone. Progesterone keeps your period away after you have conceived. In the context of IVF, HCG is used as a trigger shot to stimulate the release of eggs.
Semi-Stimulated IVF – This type of IVF is also called mild IVF. It uses fewer drugs than the standard form of IVF and it is based on the woman’s natural cycle, rather than a medically simulated one. This means the cycle is around two weeks – shorter than with a drug regime – and it carries a lower risk of developing side-effects like ovarian hyperstimulation syndrome. It is also more cost effective.
Natural IVF – Natural IVF is when invitro-fertilization is carried out with no drugs at all and relies entirely upon the woman’s natural cycle. Ultrasound technology allows fertility specialists to observe when a woman’s eggs have matured. They can then be retrieved for fertilization in a lab. This option is cheaper than standard IVF and is sometimes chosen by women because they don’t want to have stimulatory drugs or they have previously had side-effects from them.
Reasons you might need IVF include problems with the fallopian tubes, those with low egg reserve, those who have failed to respond to other treatments and couples with male factor infertility. If the male partner has a low sperm count, only one is needed for direct injection into the egg and only those of a good quality are chosen for use in an IVF cycle to give you both the best chance to conceive.
