Summary
Men with inhibited ejaculation (IE) often experience low sexual arousal, even without physical causes. Relationship factors may influence arousal levels in these individuals.
Area of Science:
- Male Sexual Dysfunction
- Psychophysiology
- Men's Health
Background:
- Inhibited ejaculation (IE) is a male sexual dysfunction with unclear causes.
- Both psychological and physical factors can contribute to IE.
- Understanding IE is crucial for effective treatment.
Purpose of the Study:
- To investigate sexual response in men with inhibited ejaculation (IE) and no apparent somatic cause.
- To compare erectile response and sexual arousal in IE men versus other groups.
- To explore the impact of diagnostic classification and relationship factors on arousal in IE men.
Main Methods:
- A psychophysiological assessment procedure was used.
- 25 men with IE (no somatic cause) were compared to control groups.
- Measures included erectile response and self-reported sexual arousal during stimulation.
Main Results:
- Men with IE reported the lowest levels of sexual arousal compared to other groups.
- Differences in erectile response were also observed between IE men and controls.
- Within the IE group, arousal levels correlated with diagnostic subtypes and relationship factors.
Conclusions:
- Inhibited arousal is common in men with IE lacking a clear physical etiology.
- Specific relationship factors may offer avenues for improving sexual arousal in IE.
- Further research into psychological and relational aspects of IE is warranted.

Accessory Ducts of the Male Reproductive System
The male reproductive system is a complex network of organs and tissues that work together to produce and transport sperm. The epididymis, vasa deferens, ejaculatory ducts, and urethra are the accessory ducts involved in sperm maturation and transportation. These ducts play a critical role in the production and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.
The epididymis is a small, comma-shaped organ located at the back of each testicle.

Sperm Transport
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.

Sperm Structure and Semen Composition
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...
Male 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.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Menopause
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...
Infertility 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...
