Is there any viable option for infertile male patients
to father a child? Yes, says a city-based doctor, who
attains the distinction of being the first medico in the
country to treat such patients successfully. The new treatment
is expected to illumine the lives of many unhappy couples.
Dr Aniruddha Malpani,
a well known specialist in infertility problems, has
successfully impregnated a woman with testicular sperms
for the first time in the country. Besides, he has also
achieved fertilisation with precursor germ cells like
spermatids , which is contrary to the known scientific
wisdom that only matured and developed sperms can initiate
pregnancy.
At least one, out of every ten couples in the country,
suffer from infertility problems, in which the contribution
of the male is nearly 50 per cent. In the case of males,
nearly 80 per cent suffer from Azoospermia, (defective
sperm generation). The sperms are produced in the testes
as a result of a complicated series of successive cell
divisions called meiosis sperms, produced by the testes,
are immobile. They become mobile after they reach the
Seminal Vesicle in the case of normal males. However,
in the case of patients with Obstructive azoospermia,
there is a block in the vas deferens or the epididymis.
Vas Deferens is a tube that carries the sperm from the
testes to the required destination and epididymis is
the store-house of the sperms. On the other hand, in
Non-Obstructive Azoospermia, the spermatogenesis (the
sperm-generative process) itself is defective, despite
a clear passage in the vas deferens or the epididymis.
“In the case of azoospermic patients, we extracted
the testicular sperms from a testicular biopsy and then
injected it into the egg by the Micromanipulation technique,”
said Dr. Malpani. “This is something wonderful
because last year, we had not even imagined that such
things could happen,” he said adding that previously
he had no choice but to resort to In Vitro Fertilisation
or Donor Insemination for such patients.
“Donor insemination, though successful, creates
a lot of psychological problems for the parents as well
as the child in later stages,” said the doctor-wife
of Dr Malpani, Anjali. “This has led to deep emotional
conflicts between the couples,” she said adding
that the females were the most resistant to Donor Insemination.
One significant thing in Dr Malpani’s treatment
is there is no over-riding necessity to satisfy the
conventional criteria like sperm count and sperm motility.
“One sperm per egg is sufficient,” says
Dr Malpani. Here, a single sperm is carefully taken
and injected into the egg by Intra Cytoplasmic Sperm
Injection (ICSI).

The micro-manipulator, used by Dr. Malpani, is a sophisticated
system, which includes a tissue –culture microscope
and pipettes of a ultra-fine cross-section ,that can
be manipulated. The sperm form the biopsy is sucked
with pipette and then carefully injected into the egg.
“Though we have many options like in vitro fertilization
and donor insemination, we do not impose anything and
leave the potion to patient’ choice,” said
the doctor adding, “ Our recent experience shows
that testicular sperm extractions, followed by ICSI,
is the best option available for azoospermic patient.”
Though micro-manipulation is common, testicular sperm
injection is a new concept in India. “ Our present
25 per cent success rate gives a lot of hope, “
enthused the pioneer adding that with increasing number
of patients in the future, the success rate would also
shoot up.
Previously, males with nonobstructive azoospermia,
elevated levels of follicle stimulating hormone and
small testes were considered to be sterile.
Dr. Malpani’s clinical success shows that even
the most sterile patient can now be successfully treated
by testicular sperm injection.
However, the treatment charges are quite expensive,
ranging around Rs 90,000 for a single attempt.
“ This cost, though cheap compared to that of
the western countries, is beyond the reach of many in
our country,” Dr. Malpani lamented, adding that
the charges would get reduced as the treatment percolates
down to a wider strata of the society.
