High Serum Estradiol and Heavy Metals Responsible for Human Spermiation Defect-A Pilot Study

Summary: | Introduction: Spermiation is a process of releasing sperm into
the lumen of seminiferous tubules. Failure in releasing sperm
into the lumen is designated as spermiation defect. Spermiation
defect cases present as oligo-azoospermia or azoospermia
despite normal gonadotropins and testicular histology/cytology.
Human spermiation defect never got attention to investigate
infertility practice. Most of the information on spermiation defect,
so far is from animal experiments. We assume some cases
of non-obstructive azoospermia with normal gonadotropins
and testicular histology/cytology could be due to spermiation
defect.
Aim: The aim of the study was to find out the underlying
aetiology in cases of human spermiation defect.
Materials and Methods:A total of 13 cases of spermiation defect
and 20 fertile men as control constituted study material. Cases
were studied for chromosomal abnormalities by conventional
karyotyping, sex chromosome mosaicism by interphase XY
FISH, Yq microdeletion by STS PCR, sertoli cell quality (function)
and quantity (numbers) by serum Anti-Mullerian Hormone (AMH)
and inhibin B besides other hormones like Follicular Stimulating
Hormone (FSH), prolactin, testosterone and estradiol. Vitamin A
concentration in serum was also measured. Presence of heavy
metal was investigated by elemental electron microscopy in
seminal cells (eight cases) & by spectrometry in serum as well
as seminal plasma.
Results: Chromosomal and Yq microdeletion study failed to
detect any abnormalities. AMH, inhibin B and vitamin A were
also normal. Estradiol level was high in 6 out of 13 cases (46%)
while platinum in seminal cells was high in 4 cases (50%). High
(four times or more) serum level of lead and nickel was observed
in 11 (85%) and 6 (46%) cases, respectively.
Conclusion: High serum concentration of heavy metals like lead
& nickel or high platinum accumulation in seminal cells or high
serum estradiol alone or in combinations may be underlying
aetiologic factors in human spermiation defect. |
