Plasma testosterone level and sexual behavior of couples
Archives of Sexual Behavior
|May 1, 1978
Summary
Hormonal fluctuations, particularly testosterone levels in women, significantly influence sexual desire and relationship satisfaction. Higher baseline testosterone in wives correlated with greater sexual gratification and better interpersonal relationships.
Area of Science:
- Reproductive Endocrinology
- Human Sexuality
- Behavioral Endocrinology
Background:
- Sexual behavior and relationship dynamics are influenced by complex hormonal and psychological factors.
- Understanding the interplay between endocrine profiles and sexual interactions is crucial for relationship health.
Purpose of the Study:
- To investigate the relationship between endocrine levels (testosterone, cortisol, progesterone, estradiol) and sexual behavior in married couples.
- To explore correlations between hormonal profiles, sexual initiation, responsivity, and self-rated sexual gratification.
Main Methods:
- Intensive study of 11 couples over three menstrual cycles, including twice-weekly blood sampling and individual psychiatric interviews.
- Measurement of plasma testosterone, cortisol, progesterone, and estradiol levels.
- Psychiatric rating of sexual initiation, responsivity, avoidance, couple interaction, and mood, with self-rated gratification by wives.
Main Results:
- Significant correlations were found between husbands' sexual initiation and wives' responsivity, and vice versa.
- Wives' testosterone levels at ovulatory peaks correlated with intercourse frequency.
- Wives' self-rated sexual gratification significantly correlated with their plasma testosterone levels.
- A dichotomy in wives' baseline testosterone levels was observed, with high levels linked to greater gratification and better interpersonal relationship formation.
Conclusions:
- Hormonal profiles, especially testosterone, play a significant role in sexual dynamics and relationship satisfaction within couples.
- Baseline testosterone levels in women may be a predictor of sexual gratification and capacity for forming good interpersonal relationships.

01:41Spermatogenesis
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...
01:17Male Sexual Response: Erection & Ejaculation
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.

01:26Testosterone: Functions and Regulation
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
01:23Infertility in Males
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...
01:20Disorders of the Male Reproductive System
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.

01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
