<p>If you need donor eggs to fulfil your dream of a child and wants to use frozen eggs, there is only one type of fertility treatment available for you: ICSI treatment.&nbsp;Because the <a href="/en-gb/cy-shop/private/about-donor-eggs/donor-eggs-for-fertility-treatment/">donor eggs</a> are frozen, the shell of the egg is still hard at the time of fertilization which makes it impossible for sperm cells to enter the egg without help.</p>
<h2><span class="display-3">What is ICSI treatment?</span></h2>
<p>ICSI treatment is short for Intracytoplasmic Sperm Injection and is a method of assisted reproduction for people having trouble conceiving naturally. ICSI treatment is similar to IVF treatment because in both types of fertility treatment the eggs are fertilized outside the body in a lab. The difference between the two types of fertility treatment is the fertilization process. In ICSI treatment each donor egg is individually injected with a single sperm cell, therefore bypassing the stage where the sperm must naturally penetrate the egg. In IVF treatment the egg is placed in a petri dish alongside sperm cells, which then need to enter the egg on their own. Because the shell of the donor egg is hard after freezing, sperm cells cannot enter the egg naturally. Therefore, the only way to complete fertilization is through ICSI treatment.</p>

<h2><span class="display-3">The process of fertility treatment with donor eggs</span></h2>
<p>In fertility treatment with donor sperm or a partner's sperm, the process will include egg retrieval from the woman. But when using donor eggs, egg retrieval is performed on the <a title="See our selection of egg donors here" href="/en-gb/cy-shop/private/find-donor/search-egg-donors/">egg donor</a>, good quality eggs are then selected, and frozen for future use of patients.</p>
<ul>
<li>The first step of fertility treatment with donor eggs is to choose an egg donor. The process of choosing an egg donor can be long, and if you need guidance on <a title="Read more on how to choose an egg donor" href="/en-gb/cy-shop/private/how-to/how-to-choose-an-egg-donor/">how to choose an egg donor</a>, follow the link. After the ideal egg donor has been selected, it is time for you to obtain the donor eggs and have them <a title="Read more about shipment of donor eggs here" href="/en-gb/cy-shop/private/how-to/how-to-order-donor-eggs/shipping-and-delivery/">shipped to your preferred fertility clinic</a>.</li>
<li>The second step starts once the donor eggs arrive to your chosen fertility clinic, a treatment plan will be arranged for you by the clinic and the frozen donor eggs will be fertilized with your partner&acute;s sperm or sperm from a donor using the ICSI treatment technique. After fertilization and embryo formation, the embryos remain in the laboratory for a few more days to monitor their growth and development.</li>
<li>The third step is the transfer of the successful embryos, where the embryologist transfers one or more of the embryos into the woman&rsquo;s uterus with a catheter. The number of embryos you wish to transfer will typically be decided between you, possibly a partner, and the fertility doctor. Often only one embryo is transferred because of potential health risks in a twin pregnancy for both the children and the mother. Hereafter, a pregnancy hopefully occurs, and the treatment is complete.</li>
</ul>
<p>If more than one embryo develops sufficiently, the excess embryos can be frozen and stored for another attempt or siblings. Embryos are an important part of fertility treatment, and if you want to learn more about them, follow the link to our blog post <a href="/en-gb/cy-shop/private/blog/what-is-an-embryo/">What is an embryo and how is it related to pregnancy?</a>.</p>

<h2><span class="display-3">How many donor eggs do I need for each treatment cycle?</span></h2>
<p>For women struggling with fertility issues, having 10 to 15 healthy eggs would be enough for a successful IVF treatment, plus having some surplus embryos for future use. In fertility treatment with donor eggs, you can often settle with fewer eggs, because of the high-quality eggs from our donors.</p>
<p>At Cryos, we make sure that the donor eggs we have are high quality. That is why we have an <a title="Read how our egg donors get screened" href="/en-gb/cy-shop/private/about-donor-eggs/screening-of-egg-donors/">extensive screening program of our egg donors</a>, where the donors are tested both physically and mentally. Therefore, we recommend you purchase six donor eggs for ICSI treatment. In general, six donor eggs should be enough to produce a good number of blastocysts (Day 5 embryos) for transfer. We always recommend you consult your doctor before ordering the eggs.</p>

<h2><span class="display-3">The success rate for fertility treatment with donor eggs</span></h2>
<p><a href="https://www.pfcla.com/blog/donor-egg-ivf#:~:text=In%20general%2C%20the%20success%20rates,fertility%20treatment%20achieved%20through%20IVF." target="_blank" rel="noopener">Studies</a> show that the rate of obtaining a pregnancy when using fertility treatment with donor eggs is about 50%. A 50% success rate is high compared to other types of fertility treatments. Cryos pregnancy data shows over 75% clinical pregnancy rate which is significantly higher than the average stated above. The high <a title="Read more about the success rate at Cryos" href="/en-gb/cy-shop/private/about-donor-eggs/success-rate/">success rate of using egg donors</a> from Cryos is due to the high-quality of eggs produced and frozen at our state of art laboratories.</p>
