Term | Definition |
---|---|
Fallopian tubes | The Fallopian tubes, also known as oviducts, uterine tubes, and salpinges (singular salpinx) are two very fine tubes lined with ciliated epithelia leading from the ovaries of female mammals into the uterus, via the utero-tubal junction. |
Penis | The male sexual organ for copulation and urination; the tubular portion of the male genitalia (excluding the scrotum). |
Vagina | A fibromuscular tubular tract which is the female sex organ and has two main functions: sexual intercourse and childbirth. |
Gamete | A reproductive cell, male (sperm) or female (egg), that has only half the usual number of chromosome. |
Diploid | A cell, having a pair of each type of chromosome, one of the pair being derived from the ovum and the other from the spermatozoon |
Semen | Contains spermatozoa, proteolytic and other enzymes, and fructose that promotes spermatozoa survival. It also provides a medium for sperm motility. |
Spermatogenesis | The process of sperm production within the seminiferous tubules in the testes. |
Testosterone | Steroid hormone produced primarily in the male testes and responsible for the development of male secondary sex characteristics. |
Scrotum | The bag of skin and muscle that contains the testes in mammals. |
Epididymis | A narrow, tightly-coiled tube where sperm are stored during maturation. It connects the efferent ducts from the rear of each testicle to its vas deferens. |
Follicle-stimulating hormone | Stimulates the growth and recruitment of immature ovarian follicles in females. In males, it is critical for spermatogenesis as it stimulates primary spermatocytes to form secondary spermatocytes. |
Sertoli cells | Part of the seminiferous tubule that helps in the process of spermatogenesis. |
Luteinizing hormone | A hormone produced by gonadotropic cells of the anterior pituitary gland. It triggers ovulation and development of the corpus luteum in females and stimulates Leydig cell production of testosterone in males. |
Testes | Also referred to as testicles, the male gonads in animals. |
Vas deferens | The duct in the testes that carries semen from the epididymis to the ejaculatory duct. |
Bulbourethral gland | An exocrine gland which secretes a clear fluid upon sexual arousal as pre-ejaculate (or Cowper’s fluid). |
Prostate | A compound tubuloalveolar exocrine gland of the male reproductive system in most mammals. |
seminal gland | A pair of simple tubular glands located within the pelvis that secrete fluid that partly composes semen. |
Ovary | A female reproductive organ, often paired, that produces ova and in mammals secretes the hormones estrogen and progesterone. |
Oviduct | A duct through which an ovum passes from an ovary to the uterus or to the exterior (called fallopian tubes in humans). |
Vulva | Consists of the female external genital organs. |
Oogenesis | The formation and development of an ovum. |
Corpus luteum | A temporary endocrine structure in female ovaries that is essential for establishing and maintaining pregnancy. |
Follicle | A spheroid cellular aggregation found in the ovaries that secretes hormones that influence the stages of the menstrual cycle. |
Ovary | A female reproductive organ, often paired, that produces ova and in mammals secretes the hormones estrogen and progesterone. |
Uterus | An organ of the female reproductive system in which the young are conceived and develop until birth; the womb. |
Endometrium | The mucous membrane that lines the uterus in mammals and in which fertilized eggs are implanted. |
Fallopian tubes | The fallopian tubes, also known as oviducts, uterine tubes, and salpinges (singular salpinx) are two very fine tubes lined with ciliated epithelia, and lead from the ovaries of female mammals into the uterus via the utero-tubal junction. |
Labia minora | The two inner folds of skin within the cleft of the labia majora. |
Vulva | The vaginal opening to the uterus. |
Mons pubis | A fleshy protuberance over the pubic bones that becomes covered with hair during puberty. |
Labia majora | The two outer rounded folds of adipose tissue that lie on either side of the opening of the vagina. |
Prenatal | During pregnancy, before birth. |
Gestation | The carrying of an embryo or fetus inside female viviparous (having live births) animals, including humans. |
Trimester | A period of approximately three months. |
