Azoospermia is not a big deal.

Azoospermia is a severe male factor in the infertility, and the occurrence is around 15% in the infertile men. There are two types of azoospermia,—obstructive and non-obstructive.
Meanwhile, we can classify Azoospermia
more detail into three major types as listed.
1. Non-obstructive
2. Hormone deficiency
3. Testicular failure
Literally, non-obstructive azoospermia refers to no sperm in
the semen because of abnormal sperm production.
The fertility specialist generally recommended these patients
to take microsurgical epididymal sperm aspiration (MESA) or testicular sperm
extraction (TESE) combing with intracellular single
sperm injection (ICSI) in the
IVF program.
How to do the MESA/TESE?
Under regional anesthesia, we would cut apart the scrotum and use a surgical microscope to open the small tubes within the epididymis to look for mature sperm or immature sperm cells. The sperm harvested can be used immediately or frozen for use at a later time. If no sperm are found in epididymis, it is necessary to look inside the testicle for viable sperm.
Usually, the number of sperm retrieved is small and poor activity. Therefore, it
is very precious. It is best to use intracellular single
sperm injection (ICSI) to increase the fertilization rate. The remaining sperm can be frozen
for future use.
This is the most effective
solution to solve azoospermia retrieving sperm.
Also, with the Vitrification, it can be used several times at a time to
achieve maximum benefit.
Through MESA/TESE and
ICSI, it helps to increase the fertilization rate by approximately 70%. About
the pregnancy rate, it’s the same as normal in vitro fertilization which is
50%-60%.

For in-vitro fertilization, the oocytes attract
the sperms with better maturation status by hyaluronic acid of the surrounding
cumulus cells.
In the 2016 annual meeting of Taiwan Society of Reproductive Medicine, Dr. Dionisios Sakkas from Boston IVF center, US, shared his experiences in semen processing and sperm selection,
1. Density：Gradient separation
2. Surface Charge：Electrophoresis
3. Morphological Characteristics: IMSI (intracytoplasmic morphologically-selected sperm injection)
4. Motility Characteristics： Microfluidics
5. Membrane Integrity：Hyaluronan(HA)-binding
Azoospermia

Male factor is one of the important issues in the infertility. Azoospermia is one of the tricky things in the male infertility. If a problem occurred in the procedure of spermatogenesis (sperm production) or sperm transport, it results in azoospermia, which means no sperms found in the ejaculated semen.
Are you afraid of testicular sperm extraction (TESE)?

Before starting the IVF program, the diagnostic microdissection testicular sperm extraction can improve the success rate of surgical sperm extraction on the oocyte retrieval day. It would be a great news in the couples with azoospermia.
