Testicular and ovarian pathology focuses predominantly on neoplasms, although not all clinically important pathologic processes of these organs are neoplastic. The majority of testicular tumors are derived from germ cells, and the majority of ovarian tumors are derived from surface epithelial cells. Many germ cell tumors in the testes and in the ovaries share common features. One important pathologic process in both the penis and in the cervix is squamous cell carcinoma, caused by the human papillomavirus HPV. In the prostate, there are basically three pathologic processes that are of most importance: acute prostatitis, benign prostatic hyperplasia, and prostatic adenocarcinoma.

The ovary is an organ found in the female reproductive system that produces an ovum. When released, this travels down the fallopian tube into the uterus , where it may become fertilized by a sperm. The ovaries also secrete hormones that play a role in the menstrual cycle and fertility. The ovary progresses through many stages beginning in the prenatal period through menopause. It is also an endocrine gland because of the various hormones that it secretes.
Before infertility testing, your doctor or clinic works to understand your sexual habits and may make recommendations to improve your chances of getting pregnant. In some infertile couples, no specific cause is found unexplained infertility. Infertility evaluation can be expensive, and sometimes involves uncomfortable procedures. Some medical plans may not cover the cost of fertility treatment. Finally, there's no guarantee — even after all the testing and counseling — that you'll get pregnant. Male fertility requires that the testicles produce enough healthy sperm, and that the sperm is ejaculated effectively into the vagina and travels to the egg.

Reproductive System: Facts, Functions & Diseases
The reproductive system is a collection of internal and external organs — in both males and females — that work together for the purpose of procreating, according to the Cleveland Clinic. Due to its vital role in the survival of the species, many scientists argue that the reproductive system is among the most important systems in the entire body. The male reproductive system consists of two major parts: the testes, where sperm are produced, and the penis, according to Merck Manuals. The penis and urethra belong to both the urinary and reproductive systems in males.
During that time, offerings like this were commonly given to the gods by people with health problems, either in the hopes of a cure or as thanks for receiving one. The offerings were generally made in the shape of the afflicted body part. Scholars think this marble penis and scrotum may have been an offering given in hopes of — or thanks for — a cure for impotence, known medically today as erectile dysfunction.
Endometriosis is when the kind of tissue that normally lines the uterus grows somewhere else. It can grow on the ovaries, behind the uterus, on the bowels, or on the bladder. Rarely, it grows in other parts of the body.
