Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

13.5K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Human Genetics

1.2K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Sex-linked Disorders01:43

Sex-linked Disorders

107.1K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Disorders of the Male Reproductive System

3.8K
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

Infertility in Males01:23

Infertility in Males

460
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Criticisms of the Evolutionary Perspective

243
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

Summary

Genetic variants may influence premature ejaculation (PE) risk, with SLC6A4 showing potential links. However, current evidence is inconclusive due to study limitations, necessitating further research with standardized methods and larger sample sizes.

Area of Science:

  • Genetics and Urology
  • Reproductive Medicine
  • Pharmacogenomics

Background:

  • Premature ejaculation (PE) is a common male sexual dysfunction.
  • Genetic factors are hypothesized to contribute to PE susceptibility.
  • Previous genetic association studies have yielded inconsistent results.

Approach:

  • A systematic literature review was conducted across multiple scientific databases.
  • Included 25 genetic association studies investigating 11 genes in relation to PE.
  • Analyzed data from 2,624 men with PE and 9,346 controls.

Key Points:

  • Significant associations between PE and gene variants were found in 19 of 25 studies.
  • The SLC6A4 gene polymorphism was most frequently studied, with mixed results.
  • Other genes, including DAT1, androgen receptor, oxytocin, and tryptophan hydroxylase 2, also showed potential associations.

Conclusions:

  • Several genes, notably SLC6A4, may be associated with PE.
  • Limitations include methodological variations, small sample sizes, and lack of reproducibility.
  • Further research using standardized methodologies and genome-wide association studies is recommended.
