This means that the sperm don't move as well as they should.
Spending a long time in a hot tub, wearing underwear that holds the testicles too close to the body can increase the testicular temperatures and impair sperm production and increased alcohol intake and smoking, can also have a negative effect on sperm count. Men who are 40 or older often have decreased fertility.
Lack of ovulation (release of eggs from the ovary). The major cause of anovulation is a condition called polycystic ovary disease, or PCOS.
Inability of the fallopian tubes to carry eggs from the ovary to the uterus. Fibroid growths endometriosis, tumors, cervical problems, or irregular uterine shape can keep the embryo from implanting in the uterus.
Fertility declines with age, and even more so after the age of 35. Conception after age 45 is rare. Being overweight or underweight can also play a role in having trouble getting pregnant.
