Here, we used nutritional geometry to examine the effect of P and C intake on ejaculate characteristics sperm number and viability and subsequent fertility in male N. How does sperm count change by age? Non-anonymous sperm donors are, to a substantially higher degree, driven by altruistic motives for their donations. Moreover, there is a growing number of studies showing that males can also adjust the proportion of viable sperm in their ejaculate to the risk of sperm competition [ 13 ] and female mating status [ 14 ]. I am wondering if her next experiment will be taste and whether salty or sweet sperm are more mobile and how her gag reflex determines volume. However, the actual number of births per sample will depend on the actual ART method used, the age and medical condition of the female bearing the child, and the quality of the embryos produced by fertilization.

The latter will be based on the reports of pregnancies which the sperm bank receives, although this relies upon the accuracy of the returns and the actual number of pregnancies may therefore be somewhat higher. The dashed red line is the nutritional rail a line in nutrient space that represents a fixed intake of nutrients that passes through the regulated intake point at a P: The growth of sperm banks and fertility clinics, the use of sperm agencies and the availability of anonymous donor sperm have served to make sperm donation a more respectable, and therefore a more socially acceptable, procedure. Sperm viability was calculated as the proportion of live sperm out of the total number of sperm counted.

Finally, key nutrients other than P and C may be responsible for regulating sperm viability in N. We calculated the point in nutritional space that individuals actively defend when given dietary choice, known as the regulated intake point, as the mean intake of P and C across these diet pairs [ 43 ]. As well as radioactive iodine you might have external radiotherapy if the cancer has spread to the bones. It is common for people to feel very tired for up to a year after treatment.
