Even though maternal mortality ratio has decreased since 1990, maternal death due to pregnancy- and childbirth-related complications remains a major problem, especially in developing regions1. Through Sustainable Development Goals, a continuation of Millennium Development Goals, the United Nations attempted to develop a framework to fight global problems; one of them is maternal mortality2.
Family planning programs, which were first intended to reduce the growth of the population, could reduce maternity death through contraceptive services to prevent unintended and high risk pregnancy, such as being too young or old, having too many pregnancies, or having too short an interval between pregnancies. There are several contraception methods that may involve men or women separately. In Indonesia, women still have the major role as contraception users; data from the Indonesian Health Profile 2014 showed that 49.67% of female users used hormonal injection as their contraception method3.
Vasectomy, one contraception method, is considered the safest and most inexpensive option for male sterilization, and no-scalpel vasectomy is preferred due to its shorter operative time and lower complication rate compared to traditional surgery4–6. However, only 0.21% prefer vasectomy to their contraception method in Indonesia3. Indonesia, the largest Moslem country, is very influenced by Islam culture, and there are still controversies regarding the use of vasectomy as a contraception method among Moslems. In July 2012, Indonesia Ulema Council (Majelis Ulama Indonesia; MUI), an institution that accommodates ulema or Moslem scholars to guide and nurture Moslems in Indonesia, issued a legal pronouncement/fatwa regarding vasectomy from haram/forbidden into halal/permissible, partly due to success of recanalization/vasectomy reversal7. Even though the fatwa still receives many controversies from other Moslem institutions in Indonesia, it might gradually change an individual’s perception regarding vasectomy.
Currently, there is no data regarding demographic characteristics of patients that have undergone no-scalpel vasectomy in Indonesia. Such data could be helpful for the government to plan and evaluate family planning programs, specifically for vasectomy services. Therefore, this study aims to learn the demographic and surgical characteristics of patients who underwent no-scalpel vasectomy in Indonesia. This study also intends to investigate patient demographic characteristics before and after the fatwa issuance.
This study protocol received ethical approval from the Faculty of Medicine, Universitas Indonesia Ethical Committee (290/UN2.F1/ETIK/2017). The data are owned by The Indonesian Association for Secure Contraception (Perkumpulan Kontrasepsi Mantap Indonesia; PKMI) and were approved for use in this study by PKMI.
This is a retrospective observational study. The data was collected from Profamilia Clinic run by PKMI, which is based in Central Jakarta City, DKI Jakarta Province, Indonesia. PKMI is a private professional association focusing on secure contraception. Data are owned by PKMI and collected from patients under the knowledge that the data may be used for future research.
Variables studied in this study were as follows: Patients’ and their wives’ age; number of children; youngest child’s age; religion; patients’ and their wives’ educational background; patients’ occupation; person who guided patients to undergo vasectomy; patient’s payment method and patients’ surgical characteristics. All variables were collected from the vasectomy medical records of patients who underwent vasectomy between January 2010 and May 2017. The medical record was designed by PKMI. Patients’ age was classified according to Indonesia Demographic and Health Survey 2012: Male module (Survei Demografi dan Kesehatan 2012 Modul Pria)8. On the other hand, patients’ wife age was classified according to high risk maternal age9. Indonesia vasectomy guidelines10 state that participants must have at least two living children or if patients have only two living children, both children must be older than two years old to undergo vasectomy. Therefore, this study also presented the number of patients who had two children with one of them still under two years of age. All other variables were classified based on vasectomy medical record10.
The data were presented in a descriptive, analytical method. Categorical data were presented by absolute value and its frequency (percentage). Numerical data were presented the mean and standard deviation if the data had normal distribution, and the median and range if the data did not have normal distribution. Any missing data was accounted for and presented in this study. Analytical statistics was used to compare patients’ demographic characteristics before and after the fatwa issuance; Chi-squared or Fisher’s test was also utilized to compare qualitative variables. Data merging was done if the data did not meet Chi-squared requirements. P-value less than 0.05 was considered statistically significant. All of analysis were done using SPSS v. 23.
There were a total of 1,497 no scalpel vasectomy procedures conducted between January 2010 and May 2017. Demographic characteristics of patients could be seen in Table 1. Most of the patients (97.4%) were paid through the governmental program.
July 2012 is when the fatwa was issued.

From 368 patients who had two children, only 25 patients had a child younger than 2 years old. Among the 1,497 patients undergoing no scalpel vasectomy, there were only 989 (66.1%) procedure reports found. All patients had infiltration with 2% lidocaine as an anesthesia technique, without any premedication, and had “Dr. Li’s three finger technique” as a surgical technique to perform no-scalpel vasectomy. All procedures used simple ligation and excision of a vas segment without using electro-cauterization. Other details of procedure report from patients included in this study are shown in Table 2.
There were a few complications reported by patients following no-scalpel vasectomy, which are presented in Table 2. This study found that no semen analysis was done within 1–3 month after the no-scalpel vasectomy procedure.
No-scalpel vasectomy is a vasectomy procedure that is widely used today, due to its advantages over scalpel vasectomy; it is considered the safest and most inexpensive method for male sterilization4–6. However, it only contributes to a small percentage of the contraceptive methods used in Indonesia. This might be because the majority of Indonesian men (70.4%) have never heard about men sterilization, and among men who were aware of male sterilization methods, 77.4% never considered to undergo sterilization8. There were many factors found to affect the selection of vasectomy as a contraception method, such as lack of knowledge and negative attitudes toward vasectomy among patients and providers, education level, age, occupation, number of children, spousal support and social norms11,12.
Indonesia is a country with the largest Moslem population in the world. There are still controversies regarding vasectomy procedures among Moslems in Indonesia. However, in July 2012, MUI declared a fatwa changing vasectomy from haram to halal in condition due to success recanalization/vasectomy reversal7. This study compared the demographic characteristics of patients who underwent no-scalpel vasectomy before and after MUI’s fatwa issuance. This study found no significant difference in patients’ age and patients’ occupation before and after fatwa issuance. However, there was a significant difference regarding spouses’ age, number of children, preligion, patients’ and spouses’ educational background, and the person who guided patients to undergo vasectomy procedure before and after fatwa issuance.
This study found that no-scalpel vasectomy procedure was most common in the age group of 40–49 years old (42.8%), followed by age group of 30–39 years old (25.5%) and 50–59 years old (24.5%). This finding is similar to other studies, which found that most vasectomy users underwent the procedure when they were over 30 years of age, but the largest proportion was at the age of 30–39 years old11,13–16. Moreover, based on Indonesian Demographic and Health Survey 2012 (Survei Demografi dan Kesehatan 2012), among patients considering vasectomy, the largest proportion was found at the age of 30–39 years old, followed by 40–49 years old9. Regarding the wife’s age, over 35 years old was the most common age of wife of patients undergoing no-scalpel vasectomy procedures. This is explained, since pregnancies over 35 years has a high risk for women. Other studies found the wife’s age of over 30 as the age for husbands to undergo vasectomy, while the mid- to late 30s was considered “typical” for Asian couples11,13,15,17. There was significant difference in wife’s age before and after fatwa issuance. However, this is most likely due to larger missing data after fatwa issuance, which could be due to poor data collection.
Among no-scalpel vasectomy patients, most of them had three children (34.3%) when they underwent no-scalpel vasectomy procedure. There were variations regarding the number of children among the patients across geographical regions. Although in general, the vasectomy was performed when the number of children was four or more in some places, in other places two or more children were enough to encourage patients to undergo vasectomy, such in the USA or Iran11–13,15. There were significant differences regarding the number of children before and after fatwa issuance. After July 2012, there were higher proportion of patients having two children and lower proportion of patients having three or more children compared to before July 2012. This could be a sign of the success of the family planning program. However, further study is needed to support this hypothesis.
Islam is the most stated religion among patients undergoing no-scalpel vasectomy in Jakarta. This is because Islam is the majority religion in Indonesia. This study found a signficant difference in patients undergoing no-scalpel vasectomy in terms of religion before and after fatwa issuance. Interestingly, however, there were no increased participation of Moslems to undergo no-scalpel vasectomy. There was a higher proportion of Christian and Buddhist patients who underwent no-scalpel vasectomy after fatwa issuance compared to before fatwa issuance. However, an increase in the proportions of both religions could not be explained.
This study also found a high proportion of no-scalpel vasectomy patients and their spouses graduated from high school, junior high school, and elementary school (patients: 32.3%, 22.4% and 22.8%; wives: 24.6%, 25.7% and 24.9%, respectively). Therefore, this study found that the majority of patients who underwent vasectomy had less than 12 years of education. Other studies showed varied education levels across regions with the majority of patients and their spouses illiterate or had low education levels in developing countries. However, in developed countries, vasectomy was more prevalent in men with high education level16–18. There were significant differences in education level for both patients and their spouses before and after July 2012. This might be due to the increased of education participation of Indonesian people, especially at junior high school and college level. This is supported by the presence of the same trend in both patient and wife education background data, which show an increase in the proportion of junior high school and college graduated. However, the government-level data regarding Indonesia’s education participation rate are currently unavailable.
Most of the patients (40.6%) undergoing no-scalpel vasectomy were suggested by family planning program officers to choose no-scalpel vasectomy as their contraception method. Family planning program officers and their cadres have an important role in helping patients to decide on vasectomy19. Data from Ghana showed that most patients gained information regarding vasectomy through media and healthcare workers, whereas only small amounts of patients gained the information from family and friends15. There was a significant difference before and after July 2012 regarding source of information/guidance who encourages patients to undergo no-scalpel vasectomy. However, this was probably due to a high proportion of missing data.
All no-scalpel vasectomy procedures were performed using “Dr. Li’s three finger technique”. This technique was developed by Dr. Li Shunqiang and was performed using ringed clamp and dissecting forcep10,20. From the procedure report, this study found that doing no-scalpel vasectomy only took a relatively short amount of time (median 10 minutes; range 7–90 minutes). Other studies found a similar short operative time for no-scalpel vasectomy6,21,22. The wide range of operating times in this study might be influenced by operator’s experience. One study found that high learning curve for no-scalpel vasectomy procedure required 10–15 operations before being able to perform the procedure perfectly23. All the procedures performed on the patients in this study were performed using infiltration as the anesthesia technique. There are several anesthetic techniques beside infiltration, such as combination of infiltration and spermatic cord block and no needle jet anesthesia. One study found that combination of infiltration and spermatic cord block was the best and the most effective method for reducing pain during vasectomy4.
This study also found that “Dr. Li’s three finger technique” was an easy procedure to conduct. Most operators felt easy in performing the steps of “Dr. Li’s three finger technique” in no-scalpel vasectomy procedure. All procedures used ligation and excision (LE) without cautery. Cautery was associated with more rapid progression to severe oligospermia and fewer early vasectomy failure24,25. However, cautery has not been adapted yet into standard practice in Indonesia. Silk was the suture material mostly used for vas ligation in this study. There were various suture materials used, such as cotton and cat gut. One study showed that the usage of vicryl increased vasectomy failure three times compared to chromic cat gut. However, until today, there was no study comparing effectiveness of silk, cotton and cat gut20,26. Most of procedures used fascial interposition (FI) as an additional step when performing no-scalpel vasectomy in this study. FI can reduce the risk of occlusive failure when performing LE and was associated with decreased time to azoospermia, decreased time to severe oligospermia and reduced failure based on semen analysis22,27. The use of combination between LE and FI varied from one country to another. There were several reasons why FI was not performed in South Asian countries, such as technical difficulties, time consuming as it adds 2–4 minutes, and national standard practice didn’t include FI as a mandatory step22.
This study found only a few complications that occurred during the no-scalpel vasectomy procedures. Another study also found few complications after no-scalpel vasectomy procedures, with an overall rate of 0.32%, consisting of hematoma, bleeding, foreign body granuloma, scrotal pain, epididymitis and sinus formation28. However, there was also a probability that patients didn’t report their complication or came to another facility, due to long distance, in this study. This study also found that no semen analysis was done after the vasectomy procedures. Based on the standard practice guideline, semen analysis should be done in the first month until the third month after vasectomy has been performed10. However, low compliance might be caused by long distance and cost. Other studies reported compliance under 30%, except for one center, in Nepal for semen analysis29.
This is the first study that which describes the characteristics of patients undergoing no-scalpel vasectomy in Indonesia. Data in this study could be useful to encourage further studies, to plan and to evaluate programs related to contraception, specifically male sterilization. However, there are also limitations in this study regarding missing data. Some variables had high missing data, such as the data regarding wife’s age and sources of information/guidance. This should encourage health care providers to pay more attention to completeness of data. Such data could be useful for a variety of goals, such as program evaluation.
Despite its limitations, this study provides a depiction of the characteristics of patients undergoing no-scalpel vasectomy in Jakarta. Even though there were significant proportional difference in some characteristics, this study considers that the fatwa was not the only factor that affects a patient’s choice of no-scalpel vasectomy. This study also found that no-scalpel vasectomy was considered an easy procedure to perform and caused minimal complications.
