What is Andrology and male Infertility? Guide by Dr Rahul Yadav
Andrology is the branch of medicine that studies the man and can be considered the male counterpart to gynecology. Andrological treatments concern the medical specialty dealing with male health, especially the male reproductive system and men-related urological problems
Male Infertility
Infertility
caused by a problem in the male, for example, inability to ejaculate or
insufficient number of sperm.
Infertility
is not just a disease that affects women—men suffer as well. In fact, new
studies show that in approximately 40 percent of infertility couples, the male
partner is either the sole cause or a contributing cause of infertility. It
affects approximately 7% of all men.
Facts about
male infertility
1 in 7 couples in India are unable to have a child.
In 40% of these couples, the problem lies wholly or partly with the male
partner.
In many cases, the underlying cause cannot be reversed, in which case assisted
conception may offer the best chance of pregnancy; this may involve surgical
sperm retrieval in advanced bases of infertility.
Causes of Infertility
Male
infertility is either due to a problem making good quality sperm, or a problem
with delivery of the sperm to the outside world.
In 75% of
infertile men, the cause remains unexplained (this is termed “idiopathic
infertility”). It may, however, still be possible for couples to conceive
naturally, provided some sperms are present.
Typical
causes of delivery problems can range from issues with erections or
ejaculation, to physical blockages, which can occur at any step from where the
sperm is made in the testicle, to its point of delivery at the tip of the
penis. Some blockages can be more easily overcome, such as a previous
vasectomy. Others, such as multi-level obstruction due to infections, or being
born without a vas tube cannot.
Issues that
can cause problems with how sperm are made include:
prescribed
drugs such as chemotherapy
recreational
drugs (cannabis, cocaine),
smoking or
excessive alcohol intake
hormonal
imbalances (thyroid/ prolactin)
previous
testicular infection, injury, or surgery
raised
scrotal temperatures including varicoceles or recent febrile illness
genetic
problems
The damage
associated with some of these situations may be reversed to allow a return to
normal fertility. Genetic problems cannot be reversed but may be overcome using
direct surgical sperm retrieval from the testicle.
Treatments
General
measures- If you have poor sperm counts, you should wear loose-fitting trousers
and boxer shorts. You should stop smoking, reduce your alcohol intake, avoid
recreation drugs and any gym supplements. You should endeavour to adopt a
“healthy” lifestyle with a balanced diet. Fertility vitamin supplements may
also have some benefits.
Management of
obstruction- Surgical bypass may be possible depending on where the level of
the obstruction lies, blockages to the ejaculatory duct in the prostate may be
overcome with resection of any obstructing cyst, blockages of the vas (sperm
duct) – most commonly seen post vasectomy & can be overcome with vasectomy
reversal.
Blockages to
the epididymis may be overcome using microsurgical epididymo- vasostomy.
In cases where
the obstruction cannot be reversed, direct surgical sperm retrieval (SSR) from
the normal but blocked testes carries a 100% success rate in finding sperm for
use with assisted conception. The choice to reconstruct or obtain sperm
surgically depends on a number of factors, including.
Ø
the
female partner’s age,
Ø
how
many children are planned?
Ø
the
time interval since vasectomy (for vasectomy reversal only)
Ø
Assisted
conception techniques
Intracytoplasmic Insemination (ICSI)
In this type
of in vitro fertilisation (pictured) a single sperm is injected directly into
an egg to fertilise it. It is useful if you have a very low sperm count or in
cases of surgically retrieved sperms. As with any IVF technique it carries
risks for the female partner due to the drug stimulation required in the egg
retrieval process. It has a pregnancy rate of approximately 30-40% per cycle.
Congenital Adrenal Hyperplasia (CAH)
CAH is a rare
cause of male infertility. It involves flaws from birth in certain enzymes.
This causes abnormal hormone production. CAH is most often diagnosed by looking
for too much steroid in the blood and urine. CAH can be treated with hormone
replacement.
Hyperprolactinemia
Hyperprolactinemia
is when the pituitary gland makes too much of the hormone prolactin. It’s a
factor in infertility and erectile
dysfunction. Treatment depends on what is causing the increase. If
medications are the cause, your health care provider may stop them. Drugs may
be given to bring prolactin levels to normal. If a growth in the pituitary
gland is found, you may be referred to a neurosurgeon.
Transurethral Resection of The Ejaculatory Duct (TURED)
Ejaculatory
duct blockage can be treated surgically. A cystoscope is passed into the
urethra (the tube inside the penis) and a small incision is made in the
ejaculatory duct. This gets sperm into the semen in about 65 out of 100 men.
But there can be problems. Blockages could come back. Incontinence and
retrograde ejaculation from bladder damage are other possible but rare
problems. Also, only 1 in 4 couples get pregnant naturally after this
treatment.
Percutaneous Epididymal Sperm Aspiration (PESA)
PESA, can be
done many times at low cost. There is no surgical cut. More urologists can
do it because it doesn’t call for a high-powered microscope. PESA is done under
local or general anaesthesia. The urologist sticks a needle attached to a
syringe into the epididymis. Then he or she gently withdraws fluid. Sperm may
not always be gotten this way. You may still need open surgery.
What options are available if no sperms can be found?
– Donor insemination (DI)
Donor semen
is carefully screened for infections and a donor selected to have similar
attributes to you. This is the only viable option if you have no sperms at all
and you do not have obstruction which can be relieved surgically.
– Adoption
If no success
is gained with other treatments, you may wish to consider adopting a child.
Your GP and local / national adoption agencies can help with this process.
