External Female Genitals

The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more pigmented, and hairless. While the...

Disorders of the Female Reproductive System

2024
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

Infertility in Females

2024
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders. Endometriosis, a condition characterized by abnormal growth of endometrial...

Reverse genetic approaches have proven extremely useful for determining which genes underly resistance to vector pathogens in mosquitoes. This video protocol illustrates a method used by the James lab to inject dsRNA into female A. aegypti mosquitoes, which harbor the dengue virus. The technique for calibrating injection needles, manipulating the injection setup, and injecting dsRNA into the thorax is illustrated.
FAQs
These cues provide different sensory channels through which the female’s reproductive state becomes behaviorally informative. Together, they can increase sexual motivation and direct attention toward investigation or courtship. Measuring responses to the encounter helps connect sensory information from the female with changes in the observer’s neural, hormonal, and behavioral state.
The reproductive state determines whether the female provides cues associated with sexual receptivity. Consequently, the observer’s reactions can reflect responses to a reproductively relevant social partner rather than social contact alone. This distinction is important when interpreting sexual motivation, reproductive physiology, and behaviors such as courtship or mounting.
Investigation, courtship, and mounting provide observable indicators of how the exposed animal responds to a sexually receptive partner. Examining these behaviors individually can distinguish attention to the female from more advanced reproductive behavior. Their patterns also help researchers relate outward actions to underlying motivational and reproductive processes.
Repeated or controlled encounters can be used to examine how an animal identifies and responds to cues from a sexually receptive female. Changes in investigation, courtship, or related behaviors may provide evidence relevant to mate recognition and learning. The paradigm therefore links social sensory information with experience-dependent changes in reproductive behavior.
Researchers can assess the exposed animal’s investigation, courtship, mounting, and other social behaviors while also examining changes in reproductive physiology. These measures provide complementary outcomes: behavior shows how the encounter is expressed, whereas physiological findings indicate associated internal responses. Together, they support analysis of sexual motivation and reproductive function.
This approach is useful when a study needs a controlled social context for examining reproductive behavior or responses to a sexually receptive partner. It can support investigations of sexual motivation, mate recognition, learning, neural mechanisms, and hormonal or other reproductive changes. Its value comes from connecting the social encounter with measurable behavioral and physiological outcomes.
