Our results indicate that the quality of semen in this cohort of sperm donors had decreased during the study period.
In general, a healthy lifestyle can improve sperm quality.
The negative impact of age, BMI and coffee intake on sperm quality could be compensated if patients had a high ejaculation frequency and shorter periods of sexual abstinence. Combinations of adverse lifestyle factors could have a detrimental impact on sperm, not only in terms of motility and sperm count but also in terms of sperm head vacuolization.
This report demonstrates that a febrile episode can have marked effects on semen parameters and sperm DNA integrity.

Careful assessment of sperm morphology may sometimes indicate the possible cause of sperm quality and fertility decrease.
Apparently, it affects sperm quality more adversely than it does sperm production.
Finally, depletion of non-sperm components may regulate sperm expenditure, which predicted that both spermatophore volume and sperm quantity decrease.
In conclusion, the capacitating ability of sperm can be significantly lowered by increasing the level of estrogens in the environment.
These effects alter sperm parameters.
It appears that these sperm are more likely to occur in men with low concentrations of sperm, or poor sperm motility or morphology.
but probably also affects the sperm oxidase.

What are the current Non-Hormonal male contraception?
10 answers
Current non-hormonal male contraception research is focused on innovative strategies targeting various aspects of sperm function and production, aiming to provide reversible and effective methods of contraception. Despite the historical reliance on condoms and vasectomy for male contraception, there is a growing interest in developing alternatives that can offer temporary fertility control without the permanent effects of surgical options or the lower efficacy of barrier methods. Recent advancements have identified several promising targets for non-hormonal male contraception. These include specific enzymes, ion channels, and transmembrane transporters that are crucial for sperm motility and fertilization. Notable examples are enzymes like PP1γ2 and GAPDHS, ion channels such as CatSper and KSper, and transporters including sNHE and ATP1A4, which have been identified as potential druggable targets due to their indispensable roles in sperm function. Additionally, the identification of reproductive tract-specific genes associated with male infertility has opened new avenues for targeted drug development, leveraging technologies like CRISPR and proteolysis targeting chimeras (PROTACs) to potentially inhibit sperm production or function. One innovative approach involves the use of an alpha-1-adrenoreceptor antagonist, administered daily to induce reversible aspermia, azoospermia, or severe oligozoospermia, demonstrating a novel mechanism for non-hormonal male contraception. Furthermore, the exploration of genes and proteins specifically expressed in the male reproductive tract has highlighted potential targets for contraception, with phenotypes ranging from disrupted spermatogenesis to abnormal sperm motility and morphology, indicating their viability for developing effective contraceptives. Despite these promising developments, the transition from preclinical research to clinically approved non-hormonal male contraceptives faces challenges, including the need for rigorous safety, efficacy, and reversibility evaluations, as well as the establishment of clear guidelines for clinical trials. The collaboration among academia, industry, and regulatory agencies is crucial to overcome these hurdles and bring these innovative contraceptives to market.

AI is commonly used for unexplained infertility and male subfertility, serving as the initial treatment choice before resorting to more invasive procedures. The process involves selecting ejaculated spermatozoa through techniques like swim-up, density gradient centrifugation, and sperm washing to enhance fertilization potential. AI's minimally invasive nature, cost-effectiveness, and acceptability make it a preferred option for cases of cervical factor subfertility, mild-moderate male subfertility, and unexplained infertility. Overall, AI in humans is a relatively non-invasive and accessible method in assisted reproduction, offering a viable solution for various fertility challenges.
What is the scientific rationale behind incubating total cholesterol samples at 37°C?
5 answers
The scientific rationale behind incubating total cholesterol samples at 37°C lies in the structural transition and configurational changes in the aliphatic chain of the cholesterol molecule. Additionally, incubating samples at this temperature can induce capacitation-like changes in sperm, affecting their quality and viability. Furthermore, maintaining a stable temperature during storage is crucial for preserving the integrity of blood specimens, as fluctuations can impact the stability of the specimen and lead to changes in cholesterol levels. Therefore, incubating total cholesterol samples at 37°C ensures that any structural transitions or changes in the cholesterol molecule are accurately reflected in the analysis, contributing to the reliability of cholesterol level measurements.
