Summary
Women charged with violent crimes were more likely to offend during their paramenstruum, the period surrounding menstruation. This association persisted regardless of psychosocial factors or premenstrual tension symptoms.
Area of Science:
- Forensic Psychology
- Reproductive Psychiatry
- Criminology
Background:
- Understanding factors influencing criminal behavior is crucial for effective intervention.
- The menstrual cycle's potential impact on female behavior, particularly aggression, warrants investigation.
- Previous research has yielded mixed results regarding the link between the menstrual cycle and violence.
Purpose of the Study:
- To investigate the association between phases of the menstrual cycle and the commission of violent offenses in women.
- To determine if psychosocial factors or premenstrual tension mediate this relationship.
- To inform clinical and legal approaches to managing female offenders.
Main Methods:
- A retrospective analysis of 50 women charged with violent crimes.
- Correlation of offense dates with specific phases of the menstrual cycle (paramenstruum, ovulation, post-ovulation).
- Assessment of psychosocial factors and premenstrual tension symptoms.
Main Results:
- A statistically significant increase in violent offenses (44%) occurred during the paramenstruum (P < 0.02).
- A significant decrease in offenses was observed during the ovulatory and post-ovulatory phases (P < 0.01).
- The observed association was independent of psychosocial factors and premenstrual tension symptoms.
Conclusions:
- The paramenstruum is a high-risk period for violent offending in women.
- Recurrent behavioral changes, rather than subjective symptoms, should guide treatment considerations for female offenders.
- Menstrual cycle phase should be considered in forensic assessments and treatment planning.

02:07Oogenesis
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
01:27Ovarian Cycle
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
01:28Menopause
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...
01:22Birth Control Methods
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although vasectomy...
01:24Primary Motives: Sleep, Sex, and Pain Avoidance
Primary motives such as sleep, sex, and pain avoidance are crucial drivers of behavior in humans and animals. These motives ensure survival, reproductive success, and overall well-being by prompting actions that meet essential bodily needs.
Sleep is a fundamental physiological drive that fosters a state of restfulness crucial for several bodily functions. It facilitates body restoration, the process by which the body repairs, rejuvenates, and maintains itself during sleep, including memory...

01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
