Antioxidants and vitamins in male
subfertility:-Many doctors do
prescribe 1)L- carnitine,2) Astaxanthin,3)
Vitamin E, 4) Vitamin C, 5) Co-Q, 6) Zn, 7) Lycopene, 8) Selenium, 9) L-arginine,
10) Alpha- Calcidol, 11) Omega-3 Fatty acids, 12) DHA and 13) F. Acid to
promote fertilizing potential of ejaculated sperms.. It is
understandable that Role of antioxidants in male subfertility is
somewhat effective?? Any head to head
trial with IUI as initial modality or antioxidants as first
modality?? I have no idea. on the role of antioxidants in male subfertility is
lacking, still many people use varieties of antioxidants in male partner defect
in empirical basis with some improvement in selected cases but not in all.
What Antioxidants to improve seminal
parameters and conception rate!!! Do
supplementary oral antioxidants improve fertility outcomes for subfertile men
when compared with placebo, no treatment or another? Recognizing the drugs are
safe in prescribed dosage but not all the mentioned agents are available in any
brand prepaertions.Cost is an issue:-Antioxidants
prescribed at right dose as male partner defect to counteract ROS in semen will
cost approx > Rs 110-150/- per day and given the earliest
possible pregancy will be 80-90 days as spermatogenic cycle is somewhere 74
days. Given this equation, which one is cost effective??. If one intends to
improve one or multiple parameter defect when no clinical abnormality is
demonstrable then antioxidants is one modality of improving seminal parameters.
What antioxidants to improve seminal parameters and conception rate!!!.Do supplementary oral antioxidants improve take
home baby rate fertility outcomes for subfertile men when compared with
placebo, no treatment or another?
There are many questions which remain
unanswered. A) What element B) combination of elements to Supplemt and at C)
what dosage? D) How long? E) How do we select out of eight commonly recognized antioxidants
which one is will help one particular person??Unfortunately, answer is not
known to us. Admittedly many of us empirically supplement antioxidants. For
instance, in cases say 10th per centile motility, as a solo
abnormality or say a case of combined
with 15th per centile morphology-what antioxidant will be most suitable if no
obvious cause is detected and couple is too young for IUI /ART? Ans: Before
initiating on antioxidants we have to exclude, as far as possible , that there is no environmental, smoking
habit, H/O Kochs, Local injury , other infective cause , hydrocele , hernia,
epididymitis, varicocele, Prostatitis,
normal reproductive hormones like normal serum
FSH Tetsos/E ratio are normal. This
is because in most cases no obvious cause is found for subnormal seminal
parameters (one parameter or two parameter defect) and it is a common practice
to prescribe antioxidants for couple of months before proceeding for IUI or say
IVF in elderly couple).
Any
adverse effect induced by the antioxidants? Many doctors to prescribe 1)L- carnitine,2) Astaxanthin,3) Vitamin E, 4) Vitamin C, 5) Co-Q, 6) Zn, 7) Lycopene, 8) Selenium, 9) L-arginine,
10) Alpha- Calcidol, 11) Omega-3 Fatty acids, 12) DHA and 13) F. Acid to
promote fertilizing potential of ejaculated sperms. It is understandable
that it is not clinically possible in day to day clinical practice to estimate
and the deficiency of such products
either in food, serum, testes or in ejaculated semen. So, as things stands
these are often prescribed empirically To estimate which micronutrient /
anti-oxidant going to help a particular subfertile man thereby evidence based selection
of such brand is often empirical. Quite often in the Indian market there are
mixture of some of the agents ( To my mind there are about at least 30 Brands)
which are liberally used as to accelerate sperm potential if 2 or 3 seminal
reports are suboptimal and trying time is < 2 yrs and couple is young . One
will be surprised to note that in some studies between 30% to 80% of all male
subfertility cases are considered to be due to the damaging effects of
oxidative stress on sperm and 1 man in 20 will be affected by subfertility of
this kind of etiology. Antioxidants are widely available and inexpensive when
compared to other fertility treatments and many men are already using these to
improve their fertility. It is thought that oral supplementation with
antioxidants may improve sperm quality by reducing oxidative stress.
What about Pentoxyphylline?? Ans: Pentoxyphylline, a drug that
acts like an antioxidant, was proved to be useful ..
Take home message:-There is low
quality evidence from only four small randomised controlled trials suggesting
that antioxidant supplementation in subfertile males may improve live birth
rates for couples attending fertility clinics. Low quality evidence suggests
that clinical pregnancy rates may increase. There is no evidence of increased
risk of miscarriage but this is uncertain as the evidence is of very low
quality. Data were lacking on other adverse effects. Many subfertile men who
are part of a couple undergoing fertility treatments are also taking dietary
supplements in the hope of improving their fertility. It is important that
these men have access to high quality evidence that informs them on the
benefits and risks of taking an antioxidant. There are minimal RCT to assess
whether oral antioxidants, minerals would increase the chances of a couple with
a subfertile male partner achieving a clinical pregnancy and ultimately a live
birth. The criteria should be Live birth, Clinical pregnancy rate,. G I
side effects, Miscarriage rate, congenital malformations. Many researchers
remarked by concluding that they were unable to draw any conclusions from the
antioxidant versus antioxidant comparison as not enough trials compared the
same interventions. Do members have any
special predilection or brand preference?
