Doctors Debunk Myth: Does Frequent Masturbation Really Shrink Male Genitals? Four Risky Behaviors Many People Do Often

Compiled by Sanook Online News Team May 7, 2025

Based on foreign media reports, many men believe that masturbation may diminish sexual performance or cause genital tissue to wear down and shrink. However, medical experts confirm that certain behaviors actually pose greater risks to sexual health than masturbation itself.

Debunking the Myth: Masturbation Does Not Shrink Genitals

According to anatomical principles, male genitals consist of cavernous tissue—sponge-like tissue filled with blood vessels. Dr. Hsu Lan-fang from Taiwan explains that this tissue is not a rigid material that can "wear away" from use.

When some men notice their genitals appear smaller after sexual activity or frequent masturbation, it's actually due to temporary erectile dysfunction caused by physical fatigue or overexertion, which prevents blood from completely filling the cavernous tissue. This results in reduced size during erection but is only temporary, not permanent tissue shrinkage.

Conversely, lack of sexual stimulation or sexual activity for more than six months may cause the smooth muscle in the cavernous tissue to atrophy and shrink. Therefore, appropriate sexual activity helps maintain tissue elasticity.

Dr. Han Liwei, head of the urology department at Zhongshan Central Hospital in Liaoning Province, China, further explains that genuine genital shrinkage typically results from chronic blood deficiency, tissue damage, or structural injury caused by disease or unhealthy lifestyle habits, rather than masturbation frequency.

Doctors Warn of Four Behaviors More Harmful Than Masturbation

1. Long-term Smoking Doctors identify smoking as a major enemy of male sexual health. Nicotine and toxic smoke chemicals cause blood vessels to constrict, particularly the small vessels supplying the cavernous tissue. When blood circulation continuously decreases, erectile tissue receives insufficient oxygen and nutrients, gradually losing elasticity and developing fibrosis, resulting in incomplete erections and apparent size reduction that may be difficult to reverse.

2. Prolonged Sitting and Physical Inactivity A modern epidemic, especially for office workers sitting 8-10 hours daily, this behavior is considered a "silent threat" to sexual health. Prolonged sitting creates pressure on the perineal area, impairing blood circulation. Additionally, lack of exercise reduces testosterone levels, a hormone crucial for muscle mass, sexual desire, and penile erection. Low testosterone can diminish sexual performance and in some cases affect genital size.

3. Late Sleep and Insufficient Rest Sleep not only restores the body but is also when the body produces male hormones, particularly during deep sleep. Regularly going to bed late or sleeping too little disrupts testosterone production, lowering hormone levels and causing incomplete erectile function, increasing the risk of erectile dysfunction.

SURAT THANI — 7 May 2026, Heavy rain in Surat Thani city caused severe roof leaks at Surat Thani Hospital on Wednesday, disrupting staff and patients inside the facility.

The incident occurred at around 13:30 as heavy rainfall swept through the province, with water reportedly pouring through parts of the hospital building "like an open tap", according to local reports.

Videos shared by the Facebook page "Monmai Surat Thani" showed large amounts of water leaking inside the hospital, while staff worked to manage the situation.

"Please help Surat Thani Hospital. Funding is urgently needed," the page wrote, expressing sympathy for hospital staff and patients affected by the flooding.

The page later stated that the OPD 2 building was an ageing structure that had been in use for many years and regularly suffered roof leaks during prolonged rainfall.

"After around half an hour of rain, the roof leaks like this. It may not be surprising because the building is very old and likely needs urgent renovation while waiting for a new building to be constructed," the post said.

The page also questioned reports that leaks had occurred in a newer special ward building on the seventh floor.

Hospital officials were preparing a formal explanation regarding the incident later on Wednesday.

The Thailand Tourism Authority (TAT) is organizing the Amazing Thailand Grand Sale 2026 to stimulate visitor spending during the mid-year period. TAT Governor Thaapanee Kiaatpaibuul emphasized that TAT is collaborating with both government and private sectors to drive Thailand's tourism industry as a vital mechanism for creating and distributing income to the people continuously, improving quality of life and promoting sustainable growth while showcasing Thailand's charm to international audiences. The focus is on quality tourism that generates revenue and distributes opportunities to tourist destinations throughout the country.

Based on statistics from 2023-2024, foreign tourists allocated 15-20% of their total spending to shopping and souvenirs, ranking third after accommodation and food and beverages. The primary markets with the highest purchasing power include the People's Republic of China, Singapore, the United States, the United Kingdom, Japan, France, Australia, India, South Korea, and Hong Kong respectively.

Therefore, the Amazing Thailand Grand Sale 2026 project has been prepared to offer discounts and special privileges in both major cities and tourist destinations to foreign visitors from June to August 2025, coinciding with the Green Season. Main activity areas include Bangkok, Chon Buri (Pattaya), Chiang Mai, Udon Thani, Phuket, and Songkhla (Hat Yai).

The initiative aims to boost spending and support the "Unforgettable Experience" campaign by creating memorable experiences for tourists while promoting Thai charm through Thai brand products and supporting Thai designers. The offerings cover fashion, crafts, jewelry, and eco-friendly products made from recycled materials, providing a premium shopping experience that is accessible to all.

Nat Kruttsutr, TAT Deputy Governor for Goods and Tourism Business, stated that the preparatory meeting with business operators aims to invite participation in the Amazing Thailand Grand Sale project to stimulate spending and travel among foreign tourists, targeting both nearby and distant markets with strong growth.

The project establishes Thailand's image as a shopping destination and delivers truly memorable Thai travel experiences. Previous years' campaigns have successfully attracted and stimulated tourist spending effectively. Data from 2024 showed circulation revenue exceeding 700 million baht during the project period, with 92.92% tourist satisfaction and 98.67% willing to recommend the activities. The top five participating nationalities were Malaysia, Singapore, the United States, the People's Republic of China, and India, while the top five benefits sought included accommodations, restaurants, activities and travel packages, shopping venues, and health and beauty services.

For 2025, TAT is shifting the project concept from "Discount-driven" to "Discovery-driven," presenting Thai brand identity and advantages in both products and services, particularly community products, crafts, and environmentally friendly goods. The authority is developing creative tourism experiences that connect local stories through designed product and service routes tailored to different tourist groups and creating shopping routes recommending shopping destinations and lifestyle areas nationwide.

Trade between Taiwan and Thailand rose by 47.8% in the first quarter of 2026 compared with the same period last year, according to Taiwan's Ministry of Economic Affairs, marking a new high in bilateral economic relations.

The Taipei Economic and Cultural Office in Thailand (TECO) said Taiwan is strengthening its role in Thailand's industrial and technology sectors through investment and talent development initiatives.

Since the launch of the "Taiwan-Thailand Tech Talent Service Platform" in late 2025, TECO said it has expanded recruitment and training programmes aimed at supporting Taiwanese businesses operating in Thailand.

In the first quarter of 2026, TECO and Taiwanese companies organised recruitment seminars at vocational colleges in Bangkok, Pathum Thani and Chonburi, reaching more than 3,000 students.

Taiwan has also established "International Talent Circulation Bases" in northern and northeastern Thailand under its INTENSE Programme, expanding technical training opportunities beyond Bangkok.

TECO said it is also working with printed circuit board (PCB) manufacturers and Thai industrial estates to improve employment pathways for Thai graduates.

According to data from Taiwan's Ministry of Economic Affairs and Thailand's Board of Investment (BOI), Taiwan ranked as Thailand's fourth-largest trading partner and sixth-largest source of foreign investment.

In 2025, Taiwanese investment in Thailand totalled 131 projects worth 273.5 billion baht, mainly in electronics, ICT and PCB-related industries.

Educational exchanges also continued to grow, with nearly 2,000 Thai students studying in Taiwan in 2025, up 5% from the previous year.

Peter Lan, TECO's representative in Thailand, said Taiwan-Thailand cooperation is shifting from traditional manufacturing toward AI and smart technology industries.

"Taiwan is not just here for trade and investment; we are committed to local talent cultivation," he said.
