Male Reproductive System: Functions, Organs & Anatomy

1. Male Reproductive System: Functions, Organs & Anatomy

The male reproductive system includes various structures and pathways to transport sperm. Learn about the anatomy, organs, and functions of the male reproductive system.

Male Reproductive System: Accessory Gland Functions

2. Male Reproductive System: Accessory Gland Functions

Ninety-five percent of semen is made from secretions from the accessory glands. Learn about the male reproductive system, the difference between sperm and semen, and the functions of the accessory glands (seminal vesicles, prostate, & bulbourethral).

Testicular Anatomy: Structure, Terms & Diagrams

3. Testicular Anatomy: Structure, Terms & Diagrams

The testes are the male reproductive organs where spermatogenesis and hormone production occur. Learn about testicular anatomy, the functions of the testes, what takes place in between the seminiferous tubules, and the importance of the testes in human reproduction.

Male Reproductive System: External Anatomy

4. Male Reproductive System: External Anatomy

The external anatomy of the male reproductive system includes the penis, scrotum, and testes, which are designed to work in unison to impregnate females of the same species. Take a closer look at the structures and functions of the human penis, scrotum, and testes.

Sperm's Journey from the Testes to Urethral Orifice

5. Sperm's Journey from the Testes to Urethral Orifice

Spermatozoa are produced in the testes, beginning a journey that plays an important role in reproduction. Explore the detailed path sperm takes from the testes to the urethral orifice with the end goal of passing on its DNA by fertilizing a female egg.

The HPG Axis: Hormones of Male Reproduction

6. The HPG Axis: Hormones of Male Reproduction

Male reproduction is controlled by hormones. Learn about this process, including how males change as they experience puberty. Explore the HPG Axis, the hypothalamus, the anterior pituitary, LH, FSH, gonads, testosterone, and inhibin.

Female Reproductive System: Internal Anatomy

7. Female Reproductive System: Internal Anatomy

The female reproductive system has multiple structures with specific purposes and functions. Learn about the internal anatomy of the female reproductive system, including the ovaries, cervix, uterine tubes, and uterus.

The Uterus and Uterine Wall: Structure and Parts

8. The Uterus and Uterine Wall: Structure and Parts

The uterus is a female reproductive organ that is essential for proper fetal development. Learn about the function of the uterus and uterine wall, the three layers of the uterus (perimetrium, myometrium, & endometrium), and how each layer functions in the proper development of a fetus.

External Anatomy of the Female Reproductive System

9. External Anatomy of the Female Reproductive System

The external anatomy of the female reproductive system involves six main structures developed from the same tissues that make the male's external genitals. Learn about the skin folds in the vulva and explore the female erectile structures, including the clitoris and vestibular bulbs.

HPG Axis: Hormonal Control of the Ovarian Cycle

10. HPG Axis: Hormonal Control of the Ovarian Cycle

The female HPG axis involves the hypothalamus, anterior pituitary and female gonads (or ovaries) and allows the brain to communicate with the ovaries using hormones. Explore the function of the HPG axis, GnRH patterns, LH and FSH hormones, and HPG signaling.

Phases of The Ovarian Cycle: Overview from Puberty to Menopause

11. Phases of The Ovarian Cycle: Overview from Puberty to Menopause

The ovarian cycle functions in phases from puberty to menopause. Explore the two parts of the ovarian cycle, how timing is involved, the puberty and menopause cycles, and the two phases of reproduction.

Follicular Phase of the Ovarian Cycle

12. Follicular Phase of the Ovarian Cycle

During the ovarian cycle, the oocyte, which is the female gamete, grows and matures through different phases, the first of which is the follicular phase. Explore the stages in the follicular phase, including primordial follicle, primary follicle, secondary follicle, tertiary follicle, and ovulation.

Luteal Phase of the Ovarian Cycle

13. Luteal Phase of the Ovarian Cycle

The luteal phase or post-ovulatory phase of the ovarian cycle occurs immediately after the ovaries release an egg. Learn what happens after ovulation occurs and discover when the formation of the corpus luteum takes place.

The Uterine Cycle: Phases and Endometrial Changes

14. The Uterine Cycle: Phases and Endometrial Changes

Hormonal changes trigger the phases the female reproduction system goes through over the course of about 28 days. Explore how the phases and endometrial changes specific to the uterine cycle prepare the female body for the implantation of a fertilized egg.

The Uterine Cycle: Menses

15. The Uterine Cycle: Menses

The uterine cycle is also called the menses or menstrual cycle which takes place each month in preparation for a possible pregnancy. Learn about the menstrual cycle including why and how it occurs.

The Uterine Cycle: Proliferative Phase

16. The Uterine Cycle: Proliferative Phase

The proliferative phase of the uterine cycle is where the endometrium of the uterus is rebuilt. Learn about the uterine cycle, endometrial zones, and the proliferative phase.

The Uterine Cycle: Secretory Phase

17. The Uterine Cycle: Secretory Phase

The secretory phase of the uterine cycle (menses) is when a suitable environment is created for an incoming embryo. Discover more about the secretory phase and its relationship to the uterine glands, progesterone, and fertilization.

The Female Reproductive Axis: Coordination of the Brain, Ovaries & Uterus

18. The Female Reproductive Axis: Coordination of the Brain, Ovaries & Uterus

The female brain emits hormones to let the ovaries know it's time to start the female reproductive process. Learn how the coordination of the brain, ovaries, and uterus results in a continuous, integrated system to prepare the body for reproduction.

Ovulation to Implantation: Oocyte's Path through Uterine Tubes

19. Ovulation to Implantation: Oocyte's Path through Uterine Tubes

Ovulation to implantation involves the journey of the oocyte through uterine tubes. Explore how the egg leaves the ovary and travels down the uterine tube, what happens to the egg if it is not fertilized, and the process of fertilization and cellular division.

Absolute Refractory Period: Definition & Significance

20. Absolute Refractory Period: Definition & Significance

This lesson is on the absolute refractory period, a time when a neuron cannot fire another impulse. This lesson will explain the mechanism behind the absolute refractory period and the function.

Relative Refractory Period: Definition & Significance

21. Relative Refractory Period: Definition & Significance

This lesson is about the relative refractory period - the amount of time that a neuron needs additional stimulus to be able to send an action potential. In this lesson, you will learn how neurons communicate, what the relative refractory period is, and why it is important for our bodies.

Gonads: Definition & Function

22. Gonads: Definition & Function

Learn what the gonads are and examine their functions. We will look into both the male and female gonads. You can take the quiz afterwards to test your understanding of these organs.
