IVF, PGD and Infertility treatment at CARE fertility. Trying to conceive? Have you suffered miscarriages? Want a baby? UK´s number 1 for fertility treatment. IVF, ICSI, PGD fertility specialists.
Here is an example of a general patient pathway but each treatment is as
individual as you are and your treatment may require slightly different
steps – CLICK each area for an explanation. Although we've successfully
taken thousands of couples through this process, it can still be pretty
stressful, so we ensure that guidance and counselling are available to you
every step of the way.
Step 1 - Getting Started
Getting Started: We appreciate that being concerned
about fertility can be worrying. As dedicated fertility specialists
we see patients from all walks of life with differing problems - those
who seek our advice because they have only recently become concerned
about their fertility, and those who have had treatments elsewhere and
need a fresh view.
Information: If you need further information or support
at any time, we are happy to help. Please feel free to ask for our
or more specific information packs from any of our CARE
centres (contact us)
Additionally we hold regular information evenings in Nottingham, Manchester
and Northampton where you can meet the staff, have a look round the
unit and ask questions. At Sheffield we'd be delighted to make you a
personal appointment to visit the clinic at a convenient time.
Step 2 - Consultation
Please feel free to call any of our centres to discuss how we can help.
Some centres will require a referral letter from your doctor that will
provide us with your relevant medical history. Once we receive this
referral we will contact you to agree an appointment. Some local units
might be happy to see patients in the first instance, without a referral
letter.
As you'd expect, we'll discuss your medical and surgical history and
talk about relevant options that are available to you. If you need further
tests or examination, we'll try to perform it there and then. We want
to minimise your journey and waiting time and will not request unnecessary
tests and will use any up to date information you have. Arrangements
will be made to check a semen sample because this helps to form an early
view of the appropriate course of treatment. All of these aspects will
be taken into account to personalize your treatment.
Step 3 - Ovarian Stimulation
To help improve the likelihood of success, drugs are used to stimulate
your ovaries, this increases the number of eggs you produce.
We have many different regimes so that we can tailor therapy to your
specific needs. In general, the stimulation drugs are administered daily,
by injection. Training will be provided by our staff on how to carry
this out.
Step 4 - Support and Monitoring
During the days leading up to egg collection your progress is monitored
regularly and closely throughout this stage of your treatment. When
tests show that your eggs are ready, there will be another injection
to help the eggs mature before collection. The timing of this final
injection is important.
Approximately 36 hours later your eggs are ready for collection and
the clinic will give you the precise time to attend for egg collection.
Step 5 - Egg and Sperm Collection
Your eggs are recovered using a vaginal ultrasound procedure. This
is a straightforward process that takes about 30 minutes, under sedation
or anaesthesia and is considered an out-patient procedure. You should
be able to go home within a couple of hours. The number of eggs collected
varies between patients.
Once collected the eggs are prepared for the next stage by the embryologist.
Collection of Sperm: Your partner is usually requested
to produce the sperm sample around the time of egg collection. Some
patients may have sperm frozen whilst others might require a surgical
sperm recovery, either under sedation or anaesthesia.
Step 6 - Egg Insemination
The prepared eggs are inseminated on the same day. This can be done
in two ways:
IVF, where the eggs are mixed with a specially prepared
sperm concentration, then moved to an incubator to fertilise;
or
ICSI (Intra-Cytoplasmic Sperm Injection), this highly
skilled procedure involves a single prepared sperm being injected directly
into the centre of an egg. The inseminated eggs are moved to an incubator
to fertilise.
Step 7 - Fertilisation and Embryo Development
Fertilisation: Fertilisation occurs when a sperm
fuses with an egg, this is checked the day after insemination (Day 1).
Successful fertilisation is indicated by the fertilized egg (zygote)
having 2 ´pro-nuclei´ (i.e. it contains two nuclei, one
containing the maternal DNA while the other contains the paternal DNA)
Zygotes at this stage are known as ´2 PN´s´. Once
observed the 2 PN´s are returned to the incubator for further
monitoring.
Cleavage: Once the Zygote divides into two cells
(by the day following fertilisation) embryo development begins. Cleavage
is the usual term used to describe the division of cells within the
embryo (because for the first five days although the embryo increases
in cell number it does not change its mass, but the cells, which get
smaller and smaller, are ´cleaved´ from the original egg
mass). Each cell of the embryo has its own developmental programme,
so that the embryo might have 2, 3, 4, 5 or 6 cells on the day after
fertilisation (Day 2). Therefore, the number of cells on Day 2 is not
critical to establishing a viable pregnancy. The quality of these embryos
is assessed and graded from 1 to 4, this is particularly important when
considering the freezing of embryos.
Step 8 - Embryo Transfer
Embryos are transferred to the womb generally by Day 2 or Day 3, but
sometimes if 'blastocyst transfer' is used, or after PGD, this occurs
on Day 5 or Day 6 . The embryo transfer procedure is straightforward
and is almost always performed without the need for sedation or anaesthesia.
The HFEA only permits the transfer of two embryos except in exceptional
circumstances. If three embryos are to be considered for transfer we
will need to discuss this very carefully with you and document our reasons
for the HFEA.
Soon after transfer a nurse will visit you and explain the next steps,
but you will be able to go home soon after.
Step 9 - Pregnancy
Assessing the outcome of your treatment is performed in two ways, first
the 'pregnancy test', which may need to be repeated, and the 'pregnancy
scan'.
Pregnancy Test: This is usually taken 14-16 days after
embryo transfer. The test results indicate whether or not an embryo
has implanted in the womb. It might be very important to repeat this
test and you will be given the necessary advice.
Pregnancy Scan: If the pregnancy test is positive
an appointment will be booked for an ultrasound scan to see if a heartbeat
is visible to show an ongoing pregnancy. Once this is confirmed you
will then be discharged into the care of your GP who will arrange ante-natal
care.
If the pregnancy test proves negative, a follow up appointment will
be arranged to discuss your future options. Support counselling is,
of course, always available.
