Reproductive Behavior

Reproductive behavior

Behavior that promotes opportunities for copulation and increases probability of fertilization

Attractivity, proceptivity, and receptivity

What are the functions of female reproductive behavior?

Proceptivity

Behaviors that encourage male to copulate

Precopulatory behavior, copulatory behavior, and postcopulatory behavior

What are the three stages of male reproductive behavior?

Precopulatory behavior

Stage of male behavior, search for a sexual partner/signs, courtship behavior, sexual arousal, and erection

Copulatory behavior

Stage of male behavior, mounting, and sexual behaviors

Mounting

Position that requires lordosis in female and elevation of males front legs to straddle caudal region of female

Intromission

Entrance of penis into vagina

Emission

Movement of seminal fluid, sperm into pelvic urethra

Ejaculation

Expulsion of semen from penis into female tract

Postcopulatory behavior

Stage of male reproductive behavior with dismount, refractory period, and memory

Refractory period

Period in which a second copulation will not take place

Reproductive

What type of behavior is initiated by cues like olfactory, visual, auditory, and tactile?

Prior to estrus, constantly

When does estradiol force reproductive behavior in the female? Male?

Corpora cavernosa

Spongy erectile tissue in shaft of penis, majority of penile interior and allows for influx of blood

Corpus spongiosum

Spongy erectile tissue surrounding the penile urethra

Penile erection

Behavior that requires elevated arterial blood to the penis, dilation of sinusoids, restricted outflow, and pressure

Fibroelastic penis

Type of penis with limited erectile tissue and no significant increase in diameter, sigmoid flexure straightens

Vascular penis

Type of penis with a significant increase in diameter, a lot of erectile/vascular tissue engorged with blood

Bull, boar, ram

What animals have a fibroelastic penis?

Stallion, dog

What animals have a vascular penis?

Ejaculation

Controlled by a simple neural reflex, the reflex expulsion of spermatozoa and seminal plasma from the male tract

Intromission, stimulation of glans, and forceful muscle contraction

What are the three parts to ejaculation?

Satiation

Further sexual stimuli will not cause immediate responsiveness or motivation

Exhaustion

No further sexual behavior can be induced even with sufficient stimulation

Refractory period

What is dependent on degree of sexual rest before copulation, age and species, degree of female novelty, and number of previous ejaculations?

Artificial vagina

Way to collect semen where a device stimulates vaginal conditions of a female in estrus

Electroejaculation

Electrical stimulation of the accessory sex glands and the pelvic urethra
