Conventional In Vitro Fertilisation (IVF) 

After retrieving the gametes, fertilisation occurs in the laboratory under the supervision of experienced embryologists. In Conventional IVF, the eggs are incubated with a specific concentration of sperm, allowing fertilisation to occur as naturally as possible. 

After fertilisation, embryos are carefully monitored as they grow in the incubator. Their development is evaluated over several days, and the highest-quality embryos are selected for transfer. Unused high-quality embryos are cryopreserved for future treatments. 

If there is a risk of genetic abnormalities or previous implantation failures, Preimplantation Genetic Testing (PGT) may be performed to select embryos without genetic anomalies, significantly improving success rates. Your doctor will advise you whether genetic testing is necessary for your Assisted Reproduction treatment. 

After the transfer, your doctor may recommend progesterone supplements to support the uterine lining, creating the best conditions for implantation and a successful pregnancy. 

Approximately 14 days after the embryo transfer, a pregnancy test will be conducted to confirm the result. This involves measuring beta-hCG levels in blood or urine. If positive, an ultrasound will be scheduled 7–10 days later to confirm the pregnancy. 

Once embryos reach the optimal development stage, they are transferred to the uterus. The embryo transfer procedure is quick and is performed in our clinic under ultrasound guidance. A catheter is used to place the embryo directly into the uterus. 

After the transfer, a brief rest of 30 minutes in a private room is recommended before resuming normal activities. Strenuous exercise should be avoided. 

During your first visit, FIV Valencia offers a personalised fertility diagnosis. Through the Individualised Diagnostic Study (EDI), we will evaluate your fertility and that of your partner, examine your medical history, and develop a treatment plan tailored to your needs. This approach ensures comprehensive care, recommending the necessary techniques to help you achieve your dream of becoming a parent. 

To increase the chances of pregnancy, your doctor will prescribe medication to stimulate your ovaries. The gonadotropin (FSH) medication plan will be tailored to encourage the development of one to three follicles, where your eggs are located. 

We will monitor your ovarian development through transvaginal ultrasounds and blood tests to ensure your follicles are developing properly. 

When at least one follicle reaches the appropriate size (typically 18mm or larger), ovulation will be triggered with a human chorionic gonadotropin (hCG) injection. Within 36–48 hours, your eggs will be released, and the best time for retrieval (follicular puncture) will be scheduled. 

Egg retrieval is performed in the clinic’s operating room under mild sedation and ultrasound guidance. Once collected, our biologists will evaluate the quality and maturity of your eggs to ensure they are ready for fertilisation. If needed, we will discuss the option of using donor eggs. FIV Valencia has its own egg donor bank to select the most suitable donor for you. 

Sperm samples are usually collected on the same day as egg retrieval. If the sperm quality is good, it is processed in the laboratory and used immediately for fertilisation or frozen for future use. 

If natural sperm collection is not possible, we can retrieve sperm surgically. If the sperm cannot fertilise the eggs, we will discuss the option of using donor sperm with you.
