Effect of oocyte activation with calcium ionophore on ICSI outcomes in teratospermia
: a randomized clinical trial.
The toxicity of pollutants of benzene and formaldehyde in indoor decoration on micronucleus in bone marrow PCE and teratospermia
Main causes of male infertility include low sperm count (azoospermia and oligozoospermia), poor vitality (necrozoospermia), low motility (asthenozoospermia), low DNA integrity, and abnormal sperm morphology (teratospermia
) (4, 5).
The increase of ROS has also been associated with sperm morphological alterations and teratospermia
Observation of the bacterial infection on sperm motility and morphology showed that Asthenospermia (motility less than 50%) 76.33% (Figure 3) and Teratospermia
(abnormal morphology greater than 50%) 86.16% (Figure 4) respectively.
(19), (20) Workers who are exposed through various industries related to lead inhalation demonstrate an increased frequency of still births, miscarriages, and spontaneous abortions, reduced sperm counts and motility, decreased fertility, hypospermia, increased rates of teratospermia
, and decreased libido.

Effect of cryopreservation on sperm DNA integrity in patients with teratospermia

Asthenospermia was observed in 37 (25.81 Percent), teratospermia
in 11 (3.26 Percent) and oligoasthenoteratospermia in 4 (9.09 Percent) of samples.
