REPRODUCTIVE
In human reproduction, the term “reproductive” typically refers to the reproductive system, which is a collection of internal and external organs in both males and females that work together for the purpose of procreating. This system is crucial for the continuation of a species, and its functions include the production of sex cells (gametes), secretion of sex hormones, and the facilitation of fertilization and gestation. Here’s a brief overview of the human reproductive system in both sexes:
Male Reproductive System
-
Primary Organs: The testes, where sperm and testosterone (the primary male sex hormone) are produced.
-
Sperm Production: Sperm are produced in the seminiferous tubules of the testes through a process called spermatogenesis.
-
Supporting Glands: Including the seminal vesicles, prostate gland, and bulbourethral glands, which produce seminal fluid to nourish and transport sperm.
-
Ejaculatory Ducts and Urethra: Pathways through which sperm are ejected during ejaculation.
-
External Genitalia: The penis and scrotum.
Female Reproductive System
-
Primary Organs: The ovaries, which produce eggs (ova) and female sex hormones (estrogen and progesterone).
-
Egg Production: Eggs develop in the ovaries and are released during ovulation.
-
Fallopian Tubes: Where fertilization usually occurs.
-
Uterus: The site of implantation of a fertilized egg, and where fetal development occurs.
-
Cervix: The lower part of the uterus that opens into the vagina.
-
Vagina: The muscular canal leading from the external genitals to the cervix of the uterus.
