Describe the sources of disruptions in fertility in males and females.
What will be an ideal response?
The intricate mechanisms that regulate fertility can be disrupted by many factors, including adverse nutritional exposures, severe stress, infection, tubal damage and other structural problems, and chromosomal abnormalities. Conditions that modify fertility appear to affect hormones that regulate ovulation, the presence or length of the luteal phase, sperm production, or the tubular passageways that ova and sperm must travel for conception to occur. Sexually transmitted infections, for example, can result in pelvic inflammatory disease (PID), which may lead to scarring and blockage of the fallopian tubes. Endometriosis isalso a common cause of reduced fertility. It develops when portions of the endometrial wall that build up during menstrual cycles leave the uterus and become embedded withinother body tissues. Endocrine abnormalities that modify hormonal regulation of fertility are the leading diagnoses related to infertility. "Unknown cause" is the next most common diagnosis, applied to about 10 percent of all cases of male and female infertility.
