A sterile man can have a child through PESA / TESE.

It is believed that there are many sterile men who want to have a child. Many men may have already given up on having a child. Nowadays, we have modern technology to help sterile men in having a baby!


Using the “Sperm collection directly from testis” method. PESA and TESE are 2 highly popular methods.

How is the difference between these 2 methods? Let’s have a look.

PESA (Percutaneous Epididymal Sperm Aspiration): This involves the same needle and syringe technique but the needle is placed directly into the epididymis. After the sperm has been extracted, it is used to fertilize with the egg through ICSI. 

TESE (Testicular Epididymal Sperm Extraction): This is an open surgical biopsy technique to remove a few testicular tissues and extract to find the sperm. Next, it is used to proceed ICSI.

The methods described above can help men who have severe sperm problems such as azoospermia, sterility or epididymal blockage which cause no sperm from ejaculation, low sperm production or low sperm quality leading to infertility. 

Therefore, it is best for men with this kind of problem to consult with a specialized doctor.

ICSI (Intracytoplasmic Sperm Injection)

ICSI (Intracytoplasmic Sperm Injection) is an in vitro fertilization procedure with the laboratory technology. Both IVF and ICSI are comprising of similar procedures. But the difference is how sperm will fertilize an egg. In ICSI program, only one best sperm cell will be selected then injected directly into a fully matured egg. Patients will be prescribed some hormonal medications. Stimulating ovaries to produce several eggs. ICSI can make a pleasant fertilization rate. As well as reduces some fertilization problems or abnormalities caused from egg and sperm. For example: multiple sperm fertilize an egg, sperm cannot penetrate the egg. The combined egg will transform to be an embryo after fertilization. Next, the embryo will be raised and will grow up among the appropriate environment inside a laboratory. Finally, the embryo will be transferred to the uterine cavity in order to implant then develop to be the fetus later on.
