, globozoospermia, large head syndrome (82), selected cases affected by potential sources of DNA damage such as varicocele (45), repeated ART failure (4), miscarriage (83), inflammatory processes or genital tract infection (12) constitute examples of this sort (64) (Table 3).
It was then that doctors diagnosed Mark, 39, with an extremely rare condition called teratozoospermia
, which causes abnormally shaped sperm.
In addition, decreased reproductive organ weights, astheno, azoo- and teratozoospermia
(Atessahin et al.
The study also confirmed that [DELTA]mtDNA affected mitochondrial respiration chain function and resulted in oligozoospermia, asthenozoospermia and teratozoospermia
leading to infertility in mice.
The role of oocyte maturity in the treatment of infertility because of teratozoospermia
and normozoospermia with gamete intrafallopian transfer.
An abnormal spermatozoon may have from 1 to 4 defects with the average number of defects calculated as the teratozoospermia
In men, the main causes of infertility are oligospermia, asthenospermia, teratozoospermia
and azoospermia, which account for 20-25% of cases (5).
17) The expression of centrin was reported to be reduced in human sperm with dysplasia of fibrous sheath, a rare form of teratozoospermia
The percent of normal sperm is reported for both the basic and complete evaluations and the teratozoospermia
index (TZI) is also reported as part of the complete evaluation.
are calculated as part of the teratozoospermia
Sperm morphology (strict criteria) was classified as teratozoospermia
(P-pattern (< 5% normal); G-pattern (5 - 14% normal)), normozoospermia (N-pattern (> 14% normal)), and testicular spermatozoa (immature, only ICSI group).
Men with oligozoospermia, asthenozoospermia, teratozoospermia
or oligoasthenoteratozoospermia were included in this study.
