When evaluating male reproductive potential, it is crucial to evaluate sperm structural abnormalities and sperm DNA damage. Apoptosis and mitochondrial membrane potential disruption are linked to sperm DNA fragmentation (SDF), which is inversely correlated with motility and normal morphology. To enable liquefaction, the semen sample is taken in a sterile collection container and incubated at 37°C for 30 minutes The samples were then split into three groups, P, G, and N, based on the morphological %. To measure chromatin condensation, aniline blue staining (AB), an acidic dye with a strong affinity for non-lysine-rich histones, was employed. The DNA maturity of the spermatozoa was assessed using AB. Sperm concentration, total sperm count, total motility, and total progressively motile sperm all had means that were above the WHO 2010 standard range. The DNA fragmentation index was significantly higher in patients with pattern P than in patients with patterns G and N, and it differed significantly (P=0.003) between the semen morphological patterns. In conclusion, as DNA fragmentation is an independent test this study showed that a low percentage of normal sperm morphology might indicate DNA integrity status.
Cigarette smoke contains a substance which is a toxic mutagenic chemical, and carcinogenic compounds, which have a negative effect on male fertility. Smoking cigarettes is associated with noticeably higher levels of the oxidative stress-causing reactive oxygen species in the seminal fluid. Because of this, smoking may cause changes to the sperm plasma membrane and a significant amount of deoxyribonucleic acid fragmentation. To study the influence of smoking on sperm chromatin immaturity and ICSI outcomes (fertilization rate, embryo grading and pregnancy rate). At the laboratories of the High Institute of Infertility Diagnosis and Assisted Reproductive Technologies and after 1-7 days of sexual abstinence, 92 males’ sperm samples were taken. After liquefaction, macro-and microscopic studies were carried out, criteria applied by the WHO 2021. Masturbation was used to obtain the sample, which was then placed in sterile containers. The relationship between the smoking and chromatin immaturity and ICSI outcomes have been evaluated. A significant positive correlation between smoking status and sperm chromatin immaturity. Furthermore, there was a negative non-significant correlation between smoking status and fertilization rate. Weak and non-significant correlations between smoking status and embryo grade 2 as well as embryo grade 3. There was a positive association between smoking status and embryo grade 1. The sperm chromatin integrity was significantly lower in the non-smoker group compared to the smoker group.
Human sperm chromatin and integrity of DNA have multiple endogenous factors, such as sperm compression and nucleoproteins, with various mechanisms all through their own sperm production and transport. The integrity of the paternal genetic material in both regular and assisted pregnancy is essential for initiating and maintaining a viable pregnancy. The study included semen samples from 100 men taken from Al Nahrain University Medical Clinic and Babylon Teaching Hospital for Women and Children. The first sperm test was based on the World Health Organization (1999), followed by a DNA integrity test that uses a DNA fragmentation test, and the third intensification test Chromatin by aniline blue dye. It was correlated negatively with the sperm count in combination with DFI and chromatin sperm with semen characteristics (r = - 0.223, p = 0.026). As well as DFI, sperm chromatin was being clinically significant associated with the rate of round cells (r = 0.39, < 0.001). DFI was positive and significantly associated with sperm chromatin in all infertile men (r = 0.958; p<0.001). DNA isolation in all enrolled men has been adversely linked with sperm/ejaculation, has been associated with the round cell count positive way and is not understanding and resolving with other parameters. The width of abstinence and beneficial cell count in all register men were strongly linked with Sperm chromatin. There was a direct relationship between the fragmentation of DNA and chromatin. This could imply that one exam can be used instead of the other.
