Why are millions of sperm needed, while only one will fertilize the egg? The battle that sperm cells give to fertilize the egg is merciless. They have no help from the female reproductive organs. The first obstacle is the cervix, a complex labyrinth that prevents many sperm from eventually entering. Those who finally succeed, have to go through a "hostile" uterus and be lead to a narrow entrance, the fallopian tube. Those which finally enter the tube - very few in number - eventually meet the egg. In more detail: Within 30-60 minutes of...

Sperm motility is a key factor in sperm quality. Seed is considered to be fertile when it has more than 20 million of moving spermatozoa. If, for example, live spermatozoa are 50 million, but only 10 million of them are motile, then the remaining 40 million which do not move, should not be taken into account when testing. Tests that measure only the number of live spermatozoa are ineffective because they can produce disputed results. FertilitySCORE is the only home test that is clinically proven that it measures both perm count and...

Γάλλοι ερευνητές φέρεται να έχουν δημιουργήσει, για πρώτη φορά σε εργαστήριο, "πλήρως σχηματισμένα" ανθρώπινα κύτταρα σπέρματος, προσφέροντας νέες ελπίδες για τις δεκάδες χιλιάδες ζευγάρια σε όλο τον κόσμο που ταλαιπωρούνται με την ανδρική υπογονιμότητα. Ο ισχυρισμός των ερευνητών μένει να επιβεβαιωθεί από ομότιμούς τους, αλλά αν επαληθευτεί, η τεχνική αυτή θα επιτρέψει σε υπογόνιμους άνδρες να δώσουν ανώριμα σπερματοζωάρια από τους όρχεις τους, τα οποία στη συνέχεια θα μετατραπούν σε ώριμα σπερματοζωάρια στο εργαστήριο.
