Objectives: Spermatic count and number of mobile forms are two very important parameters for the measurement of spermatic quality by means of sperm analysis. Numerous factors such as obesity, smoking, environment contamination, stress, or age act modifying the sperm fecundation capacity, therefore they interfere in the numbers of this two variables.
Methods: We aim to study the influence of age on semen quality. We studied 156 patients. They were divided into three groups: 20-30 years; 31-40 years; and 40-50 years. A Mackler's camera and a Nikon microscope were used for evaluation.
Results: Nonparametric statistical study was performed establishing the relationship between sperm count and mobility and age. Age-count: X2: 8.239 (p = 0.016). Non mobile spermatozoids-age: X2 = 6.871 (p = 0.032). Mobile spermatozoids-age: X2 = 7.378 (p = 0.025).
Conclusions: The age of the patient is intimately related to a decrease of the number of spermatozoids, with the decrease of the number of mobile forms and the increase of the non mobile.

Introduction: One in six people of reproductive age experience infertility in their lifetime throughout the world, often with devastating consequences. Men are often invisible in infertility research and services, yet masculinity and reproductive agency intersect within social, cultural and religious contexts to shape their experiences of infertility and masculine expression. This study aims to provide insights into the lived experience of male infertility, the availability and access of infertility services for men within the biomedical sector in Bangladesh and the potential willingness of men to use home-based semen testing.

Prostate cancer is the most common type after the age of fifty. It affects males and affects the prostate gland, which protects the function of sperm by producing semen. The current study was designed to evaluate prostate cancer infection effects on some biomarkers such as irisin, Tumor necrosis factor-TNF-α, prostate acid phosphates -PAP, Glutathione-GSH, malondialdehyde-MDA, urea, and creatinine.

Sperm motility is the prime functional attribute for semen quality and fertility of the bull. However, the bull's age directly affects the semen quality, and the bull's fertility and productive life decline with age. Even though research on age has been conducted in the past, it is still unclear how old a bull should be maintained at artificial insemination centers.

: Male infertility is influenced by physiological factors like age, as well as lifestyle factors, including physical activity. However, the specific impact of sport activity on semen parameters, and thus on male fertility, remains unclear. Specifically, the aim of this systematic review is to evaluate how an intense regime of training may affect sperm parameters in professional and non-profession athletes.

Camels () are seasonal short-day breeders, regulated by photoperiod and melatonin secretion. However, no studies have explored melatonin levels in camel seminal plasma or their relationship with testosterone, age, or climatic factors, nor is it known whether melatonin receptors exist in camel spermatozoa to respond to seminal melatonin. This study aimed to analyze melatonin levels in camel seminal plasma and its specific receptors in spermatozoa.
