While neither study group may be representative of the general male population, these findings suggest that sperm production, reflected in sperm output but not sperm density, as well as sperm morphology and viability are diminished in this population of healthy, non-infertile older men.

Does the age of the male partner impact the success of IVF treatment?5 answersAdvanced paternal age has been shown to have a significant impact on the success of IVF treatment. Studies indicate that older male partners, especially those over 40 years of age, are associated with decreased pregnancy rates, implantation rates, and ongoing live birth rates in IVF cycles. Additionally, advanced paternal age has been linked to declining sperm parameters, impaired embryo development, aneuploidy, and compromised pregnancy outcomes in IVF/ICSI cycles. However, the impact of male age on IVF outcomes can vary based on the female partner's age. For women under 35 years, the success rates of IVF treatment may not be significantly affected by the male partner's age, while for women aged 35-39, advanced paternal age can reduce normal fertilization rates and increase miscarriage rates in frozen-thawed embryo transfer cycles.
What is the average age at which men are diagnosed with prostate cancer?5 answersThe average age at which men are diagnosed with prostate cancer varies based on different studies. One study suggests that the median age at diagnosis is around 67 years. However, another study focused on younger patients found that some men were diagnosed in their 40s, with a median age of 47 years at the time of surgery. Additionally, a comparison between very young patients (≤45 years) and those of typical screening age (60-65 years) showed that the younger group had a higher frequency of family history of prostate cancer and lower PSA levels. Furthermore, a study in Africa revealed that the median age at diagnosis for African men with prostate cancer was around 66 years. These findings collectively indicate that while the median age at diagnosis is typically in the late 60s, cases can also occur in younger individuals.
What is the average age of menarche?5 answersThe average age of menarche varies across different studies. In one study conducted in Belagavi, the average age at menarche was found to be 12.4±1.0 years. Another study in Magetan found that the average age of menarche was 11 years, with the youngest age being 9 years and the oldest at 12 years. A cross-sectional study in Nigeria reported an average age of menarche of 12.68 ± 1.365 years, with urban areas having a lower average age compared to rural areas. In a study conducted in the North Bačka region of Serbia, the average menarcheal age was 12.23 ± 1.18 years. A study in Bharatpur Metropolitan city in Nepal found that the age at menarche ranged from 10-14 years. Overall, the average age of menarche appears to be around 12 years, but there is some variation depending on the population and geographical location.
