Sperm morphology fertility

It basically looks at the shape and appearance of the sperm head, midsection, and tail. The mid-piece contains enzyme and multiple mitochondria which supplies energy to the sperm for the journey through the female cervix, uterus and uterine tubes. The tail is made up of protein fibres and helps the sperm to swim forward in the female genital tract to meet the egg. Traditionally, male fertility investigation relies on this standardised analysis of the semen parameters morphology, motility, count. And the diagnosis is dependent on the microscopical assessment and biochemical assays, which determines the quality of the semen. Normal sperm morphology range varies between 4 to 14 percent.

A six-month study among previously sedentary men in Iran found that those who were randomly assigned to start exercising on a treadmill improved the quality of their sperm in terms of volume, sperm count, motility and morphology shape and size. All the men in the study were assigned to do either moderate intensity continuous training running at moderate speed for 30 to 45 minutes, three to six days a week , high-intensity continuous exercise running vigorously for one hour on the treadmill, three days a week , high intensity interval training alternating minutes of sprints and walks for 20 to 30 minutes or no exercise at all. All exercising groups significantly decreased their weight, body fat percentage and waist circumference. The moderate intensity group improved their semen volume by more than eight percent. Their sperm motility was 12 percent higher, morphology improved 17 percent and they had 22 percent more sperm cells on average compared to the control group, which did no exercise. But a week after exercise stopped, sperm count, shape and concentration dropped back to normal levels.

Dads-to-be: how your age can affect your fertility and your baby's health

Background: Although semen analysis is routinely used to evaluate the male partner in infertile couples, sperm measurements that discriminate between fertile and infertile men are not well defined. Methods: We evaluated two semen specimens from each of the male partners in infertile couples and fertile couples at nine sites. The female partners in the infertile couples had normal results on fertility evaluation. The sperm concentration and motility were determined at the sites; semen smears were stained at the sites and shipped to a central laboratory for an assessment of morphologic features of sperm with the use of strict criteria.

Sperm morphology refers to the shape of the sperm, which includes head size and head DNA content revealed by a nuclear color stain , the midpiece appearance and the structure of the tail. Sperm morphology is assessed during routine semen analysis that examines the sperm cells under a microscope. The semen analysis will also examine the motility movement ability and concentration of sperm present.
