A males ejaculated semen can vary up to 40% in volume sperm count and sperm motivility 100 vasectomized men were studied before vasectomy for sperm counts of single specimens; 15% of these men (all fathers of 2 or more children) had sperm counts considered by accepted standards to be ...
Semen Volume: The amount of fluid ejaculated during ejaculation. Sperm Concentration: The number of sperm cells in a given volume of semen. Sperm Motility: The ability of sperm cells to move and swim effectively. Sperm Morphology: The size, shape, and structure of sperm cells. And More! Lega...
Sperm Count - Normal vs Oligospermia Normal sperm count typically ranges from 15 million to 200 million sperm per milliliter, whereas oligospermia is diagnosed when sperm count falls below 15 million sperm per milliliter, potentially affecting fertility
the sperm concentration is used to calculate the total sperm count with the help of the semen volume. Standard values: >15 × 106spermatozoa per ml or >39 × 106total sperm count.
Seminal LH values were constantly higher than serum LH values in the normozoospermic group, whereas in the oligozoospermic group seminal LH values were higher, similar, or lower than serum LH values. However, no significant difference was noted between the two groups for seminal LH values: ...

The primary aim of this study was to explore the effects of normal morphology sperm count on two pronucleus formation time following intracytoplasmic sperm injection in infertile couples with teratospermic males. The secondary aim was clinical pregnancy. Materials and...
