Effects of smoking on ovulation induction for assisted reproductive techniques**Presented at the 39th Annual Meeting of the Society for Gynecologic Investigation, San Antonio, Texas, March 19 to 21, 1992.
To determine the effects of smoking on ovulation induction for assisted reproductive techniques.
Matched, retrospective, cohort study.
Outpatient University endocrine/infertility program.
Eighteen smokers and 36 nonsmokers: 2 nonsmokers matched to each smoker for age, weight, and history of ovarian surgery.
During a stimulation cycle, the serum estradiol (E2) level, number of follicles, number of oocytes, number of embryos, and ampules of gonadotropins used were compared in the smoking versus the nonsmoking groups by Wilcoxon's signed rank test for paired data. Follicular fluid (FF), testosterone (T), androstenedione (A), E2, A:E2 ratios, and T:E2 ratios were measured and compared between groups by Mann-Whitney U-tests.
Smokers had significantly lower serum E2 levels, fewer follicles, fewer oocytes retrieved, and fewer embryos per cycle than nonsmokers, despite equal amounts of gonadotropin administration. Follicular fluid obtained from mature follicles had a higher A:E2 ratio and a higher T:E2 ratio in smokers compared with nonsmokers.
Smoking adversely affects ovulation induction parameters and alters the FF hormonal milieu.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 May 2014.
All research outputs
#7,591,124
of 34,410,315 outputs
Outputs from Fertility & Sterility
#3,590
of 12,466 outputs
Outputs of similar age
#5,101
of 27,272 outputs
Outputs of similar age from Fertility & Sterility
#4
of 33 outputs
Altmetric has tracked 34,410,315 research outputs across all sources so far. This one has received more attention than most of these and is in the 73rd percentile.
So far Altmetric has tracked 12,466 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 11.8. This one has gotten more attention than average, scoring higher than 63% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 27,272 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 65% of its contemporaries.
We're also able to compare this research output to 33 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 57% of its contemporaries.
