The characteristics measured by semen analysis are only some of the factors in semen quality. One source states that 30% of men with a normal semen analysis actually have abnormal sperm function.
Wisps of dust and gas from the nebula which formed the star can also be seen. Credit: Atlas Image courtesy of 2MASS/UMass/IPAC-Caltech/NASA/NSF. Named for the first of their type observed, T Tauri stars are variable stars which show both periodic and random fluctuations in their brightnesses. They are newly-formed (< 10 million years old) low to intermediate mass stars (< 3 solar masses) with central temperatures too low for nuclear fusion to have started.
Utter proof of Nibiru and Nemesis despite NASA! The planet NIBIRU revolves around Nemesis, a dark subdwarf star more massive than Jupiter. Nemesis nears our Sun, at the KUIPER BELT, 48 Astronomical Units from Earth, every 10,800 Earth years. Nibiru circles Nemesis but did not orbit our sun.
