Additionally, it stores unused oocytes from IVF treatments and those from women preserving fertility due to medical (e.g., oncological treatments) or personal reasons.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In contrast, our clinic features<\/span><b> internal egg donors<\/b><span style=\"font-weight: 400;\">, providing several advantages over traditional egg banks.<\/span><\/p>\n<h2><strong>Who are the donors in our egg bank?<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">The requirements established by the Spanish Society of Fertility (SEF) and mandatory for egg bank donors are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Being aged between 18 and 35 years old.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Presenting a good physical and psychological health condition.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Not suffering from genetic, hereditary, or transmissible infectious diseases.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The same donor has given birth to no more than 6 children.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">In the egg banks of clinics, other criteria may be specified or added.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, <\/span><b>in the Equipo Juana Crespo egg bank, donors are between 18 and 30 years old, with a Body Mass Index between 18 and 25<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Nearly 80% are pursuing or have higher education, and most are also bone marrow and blood donors, which adds an altruistic character to their donation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In fact, in our clinic, solely economic motivation is a reason for exclusion from the donor program.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Advantages of having our own egg donors<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Having our own egg donors comes with numerous benefits.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The most notable ones are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">We can <\/span><b>customize each stimulation<\/b><span style=\"font-weight: 400;\"> and <\/span><b>select donors based on stricter criteria<\/b><span style=\"font-weight: 400;\">, crucial considering many of our patients have highly complex reproductive needs.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">We can <\/span><b>strategically plan egg extraction according to the cycle, surgical needs, or the endometrial preparation <\/b><span style=\"font-weight: 400;\">of the recipient.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">We can <\/span><b>maximize donor-recipient matching<\/b><span style=\"font-weight: 400;\"> based on each patient&#8217;s reproductive needs (uterus type, previous treatments, semen quality, etc.), following medical criteria while also considering relevant factors like physical appearance.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">We can <\/span><b>perform cycles with both fresh and frozen eggs<\/b><span style=\"font-weight: 400;\">. Pregnancy rates are similar with vitrified and fresh eggs, though the latter is less common as it requires synchronization between donor and recipient (ovarian stimulation and embryo transfer occur in the same cycle).<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Overall, having our own donors ensures quality in obtaining, evaluating, and distributing donated eggs, facilitating matching between donor and recipient.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Additionally, <\/span><b>avoiding reliance on third-party egg banks<\/b><span style=\"font-weight: 400;\"> streamlines procedures, provides security and peace of mind to recipients, and reduces costs.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">From a technical standpoint, having our own donors translates to better results: 84.4% of our eggs fertilize, and the pregnancy rate in egg donation cycles stands at 77.36%.<\/span><\/p>\n<h2><strong>Who are the recipients of our egg bank?<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">In vitro fertilization (IVF) with <\/span><a href=\"https:\/\/www.juanacrespo.es\/en\/treatment\/egg-donation\/\"><span style=\"font-weight: 400;\">egg donation<\/span><\/a><span style=\"font-weight: 400;\"> is an assisted reproduction treatment that enables a woman to achieve pregnancy using eggs from an anonymous donor.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It is considered when a woman cannot use her own eggs, typically due to low ovarian reserve or poor egg quality.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some cases where egg donation is recommended include:<\/span><\/p>\n<h3><strong>Patients without ovarian function:<\/strong><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Primary ovarian failure.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><a

abnormalities transmissible to offspring.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Repeated failures in IVF cycles.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Advanced age.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Opting for an in-house egg donor bank is also viable for women who&#8217;ve had surgeries affecting ovarian tissue or undergone radiation\/chemotherapy without prior egg freezing.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Typically, hesitation to use donor eggs arises from worries about the child lacking the woman&#8217;s genetic data.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, despite being a difficult decision at times, <\/span><b>assisted reproduction treatments with egg donation have a high success rate<\/b><span style=\"font-weight: 400;\">, and our psychological team provides emotional support to patients during the entire journey.<\/span><\/p>\n<h2><strong>How is the egg retrieval process performed for donors?<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">The egg retrieval process for our donors is similar to that performed on patients for <\/span><a href=\"https:\/\/www.juanacrespo.es\/en\/ovarian-stimulation-phases\/\"><span style=\"font-weight: 400;\">ovarian stimulation<\/span><\/a><span style=\"font-weight: 400;\"> in an IVF treatment.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Following a thorough gynecological examination of the donor, she is briefed on the entire process, provided with required medication, and instructed on its administration.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">After 10-12 days, she is scheduled for <\/span><b>oocyte puncture<\/b><span style=\"font-weight: 400;\"> or <\/span><b>egg retrieval<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In the case of Equipo Juana Crespo, the process takes 15-20 minutes and is performed directly in our facilities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A few hours later, the donor is released and can return to her regular activities.<\/span><\/p>\n<h3><strong>Vitrification of eggs and sample storage<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Egg vitrification involves <\/span><b>ultra-rapid freezing extracted eggs<\/b><span style=\"font-weight: 400;\"> to preserve them for future use, preventing internal water from forming ice crystals.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Stored in specialized containers with liquid nitrogen at -196\u00b0C, eggs can maintain quality for years.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These containers are meticulously organized and linked with donor data via automated systems, enhancing safety and efficiency while maintaining comprehensive activity records.<\/span><\/p>\n<h2><strong>How is the matching process between egg recipients and donors at Equipo Juana Crespo?<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">As previously mentioned, one benefit of utilizing our own donors is the possibility of <\/span><b>matching donors and recipients more thoroughly<\/b><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When selecting a donor, we seek the highest compatibility with the recipient woman and her familial context.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Qualified specialists handle the selection and allocation of donors, adhering to medical criteria such as:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Phenotypic compatibility<\/b><span style=\"font-weight: 400;\">: physical traits such as build, race, skin color, eye color, hair type, and color.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Immunological compatibility<\/b><span style=\"font-weight: 400;\">: blood group and RH factor.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Genetic compatibility<\/b><span style=\"font-weight: 400;\">: between the donor and the male partner providing sperm to ensure that the future embryo is free of genetic mutations.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Additionally, we conduct a <\/span><b>compatibility test <\/b><span style=\"font-weight: 400;\">between the donor and the male partner providing sperm to ensure that the future embryo is free of genetic mutations.<\/span><\/p>\n<h2><strong>Can it be guaranteed that the same donor will be available for another cycle if a patient decides to have another child?<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">This is a common question among our patients, and the answer is no.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">According to the legislation of our country, <\/span><b>egg donation is always anonymous<\/b><span style=\"font-weight: 400;\">, voluntary, informed, and without financial compensation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Confidentiality, both regarding the donor&#8217;s health data and the results obtained during all processes, is also protected and endorsed by law.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Regarding the assurance of using eggs from the same donor for a second time, <\/span><b>no clinic can offer it<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The reason is simple: there is the donor registry, SIRHA, <\/span><b>which aims to reduce consanguinity<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As a result, a donor can only <\/span><b>contribute to a maximum of 6 pregnancies,<\/b><span style=\"font-weight: 400;\"> inclusive of her own offspring. Consequently, if there are no embryos available, we are unable to proceed with additional cycles utilizing the same donor once this limit is reached.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Interested in learning more about our egg bank and the treatments offered at our clinic?
