Many couples face infertility due to multiple reasons and one of them can be male infertility. To resolve this problem, couples can opt for PESA and TESA procedures that use advanced technology and methods to help treat infertility so that patients can get a chance at expanding their families.
Often infertility can be caused by low motility of the sperm or low morphology which leads to difficulty in conceiving. However, couples with male infertility issues can opt for PESA and TESA procedures which are a type of needle aspiration technology that is used in retrieving sperms from the patient's epididymis, or through needle biopsies of the testis. These two procedures have been known to effectively give an opportunity to the male partner of fathering a child.
If a patient is suffering from male infertility, PESA (Percutaneous Epididymal Sperm Aspiration) and TESA (Testicular Epididymal Sperm Aspiration) are definitely two options that they should consider. Both of these procedures are done by extracting the patient's sperm from their semen sample of by conducting a testicular biopsy. Afterward, the healthiest sperm is selected for a direct inion with an egg, which facilitates fertilization and leads to pregnancy.
The PESA and TESA procedures may become necessary for patients who are unable to achieve pregnancy caused of male infertility. Reasons for male infertility can be:
• Having a low sperm count
• Having poor sperm motility
• Blockage in ducts
• Difficulty in ejaculation
• Increased number of abnormal sperm
• Poor morphology
• Having an infectious disease
• Having immune-mediated infertility
If a patient's sperms is unable to fertilize eggs regardless of going through many IVF cycles, our reproductive specialists may recommend that the patient opts for PESA and TESA. These procedures are also beneficial for those who may have an extremely low sperm count.
Both these procedures used to retrieve sperms are included in the in-vitro fertilization process which starts with the patient being induced with ovary stimulants that can increase the number of eggs that are mature as well as improve their health in the ovaries.
While the patient is on ovarian stimulants, their doctor will consistently monitor the progress of the development of ovaries by conducting ultrasounds as well as blood tests. Once the eggs have matured to the desired number and size, the doctor then removed them from the uterus via the cervical cavity by performing a minimally invasive procedure.
The next step in the process is retrieving the sperms which also is dependent on what the underlying problem is that is causing male infertility. In cases when there is a blockage in the ducts, the doctor will collect the sperms through surgery. However, if the sample collected does not have the required amount of sperm, then the doctor will conduct a biopsy that removes tissues that contain sperms from the testicles or from the region where they are blocked through the use of percutaneous or a testicular sperm aspiration.
After the sperm has been collected, the sample is then sent to an embryology lab where the doctor will select the healthy sperm by using a microscope and later inject them into the healthy eggs. After a 24-hour time period, the egg that was injected with the sperm is examined to check for any signs of fertilization.
After the fertilization process begins, the doctor will monitor the progress for approximately 5-7 days under controlled settings to check the development of the embryo. At this point in the process, if the patient would like to check if the embryo has any signs of chromosomal abnormality by getting an IVF Genetics test done. Afterward, the embryo is then transferred into the uterus to achieve pregnancy.
The PESA and TESA procedures have proved effective for many couples who go through the problems of infertility. If you have any queries regarding PESA and TESA and would like to book a consultation, you can schedule an appointment with one of our fertility specialists through the online booking form available on our website.
