The following link will take you to a summary of ALL the survey responses from the most recent version of the Centchroman Users Survey: Summary of Survey Results A total of 54 people took the survey, although 3 of those surveys were not completed. A few questions were added after some people had already taken the survey, and not all of those users returned to the survey to complete those questions. Each question is listed, along with the total number of people choosing each response, and the % of people choosing each response; The total number of people who answered that question will be listed as well (Depending on the question, not all people may have had reason to answer it). Sometimes the total % will exceed 100% because it was a question permitting multiple answers. Next to the "Other" category, you can click "View" to see what other answers were provided. These are "unfiltered" results... meaning, there is no way yet to draw any correlations, for example, comparing the prevalence of a side effect relative to recent past use of hormonal methods. In upcoming weeks, I plan to further summarize the results so that we can make such comparisons. These results simply show you the "raw" number or % of people with particular side effects, experiences, or personal/lifestyle characteristics, but you can not yet "cross compare" those factors. A few tidbits of information to note (with more detail to follow later):<ul style="list-style-type: disc">[*]30 of the 54 respondents are still using Centchroman, and the other 24 are users who tried it and then stopped. A number of AWH members who were confirmed as users did not read the private message announcing the survey. I do not know if they 1) found out about it through one of the other email groups, 2) read it on the forum but did not read their PM, 3) have stopped using it and moved on, or 4) are still using it happily and have no reason to keep looking at the forum. I suspect there are at least some in each category. I'm sure some women tried it, stopped, and moved on... and I'm also surprised periodically when a user returns to the forum and posts after months of being away.[*]16 current users have been taking Centchroman for over a year; 7 users have taken it more than 6 months (but less than a year), 1 user has taken it over two years, and 1 user has taken it over 4 years; This does not include myself, who used it for about 1 ½ years. (19 total over 1 year)[*]The most commonly reported side effects (side effects that persisted, listed in descending order of the % of women experiencing): vaginal dryness (19%), hot flashes (17%), abdominal pains/cramps (13%); Some additional women experienced some of these side effects, but they ceased after a period of time and did not persist.[*]The side effect noted in clinical studies – longer cycles (>35 days) – was experienced at least once by the majority (~70%) of women. [*]The majority of women noted at least some symptoms suggesting ovulation during at least some months, including pinch/cramps (39%) and fertile cervical fluid (28%); 12% of women confirmed ovulation with the detection of a basal temperature shift, however I do not know how many total women were tracking their temperature, and if any of those that were temping could never detect ovulation that way. At least one woman felt she could never see a shift while on Centchroman.[*]3 women reported a pregnancy while using Centchroman; Interestingly, all 3 of these women also stated they had a pregnancy PRIOR to starting Centchroman (demonstrating known fertility); This surprised me, and made me wonder if they misunderstood the question, or if they are just clearly women with healthy fertility.[*]21 of the other 51 women reported a pregnancy prior to Centchroman, including 12 of the 30 women still using Centchroman.[*]A Pearl Index was calculated as described here; The calculation was based on the number of months, not cycles, because of the common deviation away from a standard 28-day cycle. The questions needed to calculate the Pearl Index were only answered by 28 of the 54 women. A Pearl Index based on calendar months for this small sample group is: 2/409*1200 = 5.87. Clearly this is higher than the 1.2-1.3 found in various clinical studies. This would translate into an "effectiveness" rating of about 94%. The sample size of only 28 women is not scientifically sound (even 54 would not have been), but this group represents women different in ethnicity and lifestyle than those who were included in the published clinical studies.[/list] I also plan to make similar summaries of the responses from the first user survey that was done, including a look at repeat survey takers based on the "tracking names" provided. This represents just a quick look at the raw data of this past survey. The Most Important Thing!... In order to make efficient use of all the survey data, I must have specific questions in mind to answer. I do have some of those questions in mind (for example, "Are side effects more common in users who recently quit hormonal methods?" and "Are there any common factors among the women reporting a pregnancy?"), but I want Ideas from You! Please post them here, or send them to me in a private message.
