Antibiotics Before Conception: Examining Potential Risks
Table of Contents
A recent meta-analysis published in the journal eClinical Medicine suggests a possible connection between taking antibiotics before trying to conceive and experiencing adverse pregnancy outcomes, including reduced fertility, miscarriages, and birth defects. however, a leading German reproductive toxicology expert cautions against jumping to conclusions.
“It would be fatal if women who want to have children refuse necessary antibiotic therapy because they are afraid of infertility, miscarriages and malformations,” warns Dr. Wolfgang paul, from the advisory center for reproductive toxicology at Ulm University Women’s Hospital. In an interview, Dr. Paul expressed concerns not only about the study’s conclusions but also the methodology used in selecting the studies included in the meta-analysis.

The meta-analysis, conducted by Dr. Bekalu Cassie Alemu and colleagues from the Department of Obstetrics and Gynecology at the Chinese University of Hong Kong, reviewed 15 studies encompassing over 1.2 million women of reproductive age. The research examined various outcomes, including fertility, miscarriage rates, and the occurrence of congenital malformations.
mixed Data and Methodological Concerns
Dr. paul points out a significant flaw in the research: the inclusion of studies with mixed data. Eleven studies focused on fertility, primarily among women struggling to conceive. Though, a large study of Danish pharmacy workers exposed to antibiotics occupationally was also included. this raises concerns about the validity of combining therapeutic antibiotic use with occupational exposure.
“Not only did this study not examine the therapeutic use of antibiotics at all, but in this context there is a complete lack of biological plausibility.”
Dr.Wolfgang Paul
Four studies in the meta-analysis investigated the link between preconception antibiotic use and miscarriage, while two focused on congenital malformations. The varying methodologies and inclusion criteria across these studies further complicate the interpretation of the overall findings.
Expert Advice and Future Research
dr. Paul’s concerns highlight the importance of careful interpretation of research findings and the need for further, more robust studies to clarify the relationship between antibiotic use before conception and pregnancy outcomes. He emphasizes that women should not delay or forgo necessary antibiotic treatment due to fear of potential complications. The potential benefits of treating infections far outweigh the currently uncertain risks associated with preconception antibiotic use, based on the available evidence.
This research underscores the ongoing need for more extensive studies to fully understand the complex interplay between antibiotic use, reproductive health, and pregnancy outcomes. Future research should focus on clarifying the specific types of antibiotics, dosages, and timing of use that might potentially be associated with increased risk, as well as exploring potential mediating factors.
Preconception Antibiotic Use Linked to Fertility Issues, study Suggests
A recent meta-analysis has raised concerns about the potential impact of antibiotic use before conception on women’s reproductive health. The study, published[[[[Insert Publication Date and Journal Name Here], suggests a correlation between exposure to certain antibiotics prior to pregnancy and increased risks of infertility, miscarriage, and congenital anomalies.
Researchers found that women who used macrolide antibiotics, such as azithromycin, before attempting conception experienced a 35% reduction in fecundability (the probability of conceiving in a given menstrual cycle). However,Dr. Wolfgang Paul,[[[[Insert Dr. Paul’s Title and Affiliation],cautions against a direct causal link. ”Macrolide antibiotics are classically used for chlamydia, and chlamydia infection is a prominent factor in patients with an unfulfilled desire to have children,” he explains.”The chlamydia often has already caused damage,such as inflammatory processes in the fallopian tubes,contributing to infertility,and antibiotic management may not eliminate this damage.”
the study also revealed a 2.35-fold increased risk of infertility among women who used sulfonamides before conception. though, the results were not consistent across all antibiotic classes. While chlortetracycline appeared to increase infertility risk, oxytetracycline seemed to have the opposite effect.
Interestingly, the meta-analysis showed a decreased probability of infertility (64% reduction) with beta-lactam antibiotics (excluding penicillin G) and a 13% lower probability with quinolone antibiotics. This finding requires further examination.
Increased Risk of Miscarriage and Birth Defects?
The study also analyzed the association between preconception antibiotic use and negative pregnancy outcomes. Based on the data, researchers reported a 34% increased risk of miscarriage with any antibiotic exposure before conception. Furthermore, the use of trimethoprim before conception was linked to an 85% increased risk of congenital malformations.
“Most antibiotics have half-lives in the range of a few hours. Antibiotics administered preconception can therefore hardly have a direct effect on embryonic development,” says Dr. Paul.
Dr. Paul emphasizes that extensive data exists on the use of most antibiotic classes during the critical period of fetal organ development,and these data do not show an increased risk of malformations. “An increased risk of malformations if exposed before conception thus seems all the less plausible,” he states. the study authors hypothesize that antibiotics might negatively impact female reproductive health by disrupting the gut microbiome. The reasons behind the reduced infertility risk associated with beta-lactams and quinolones remain unclear and warrant further research.
The study concludes that preconception antibiotic exposure increases the risk of infertility, miscarriage, and congenital anomalies. However, the effects vary substantially across antibiotic classes. while macrolides,sulfonamides,and trimethoprim appear to increase these risks,beta-lactam and quinolone antibiotics seem to have a protective effect.

Expert Challenges Study Linking Antibiotics to Infertility
A new study linking antibiotic use to infertility and miscarriage has drawn sharp criticism from a leading reproductive toxicologist, Dr. Wolfgang Paul. while acknowledging the potential for antibiotics to disrupt the vaginal microbiome, Dr. Paul argues the study’s conclusions are overly simplistic and potentially harmful.
“It is conceivable that the use of antibiotics damages the physiological environment, for example in the vaginal area, and unwanted germs may then settle in, which in turn lead to more unfavorable outcomes such as infertility and miscarriages,” Dr. Paul admits.He further explains that antibiotic therapy’s disruption of the microbiome could lead to deficiencies in essential vitamins and trace elements, such as folic acid, potentially impacting organogenesis. he suggests that probiotics could help restore the intestinal and vaginal flora after antibiotic treatment.
However, dr. Paul strongly disagrees with the study’s central conclusion. He points out that the meta-analysis, largely based on observational studies, failed to establish a direct causal link between antibiotic use and the negative pregnancy outcomes. He criticizes the study’s highlighting of quinolone antibiotics as less problematic: “Quinolone antibiotics are highlighted here as positive, as if they were less problematic for patients who want to have children,” he says.
Dr. Paul emphasizes the significant risks associated with quinolone antibiotics, nonetheless of pregnancy plans. These antibiotics are known to cause damage to tendons, muscles, joints, and the nervous system, and are generally reserved for situations where other options are ineffective. “Quinolone antibiotics should not be given during pregnancy as they have already caused problems in animal experiments, and not before pregnancy due to the range of side effects,” he stresses.
Quinolone antibiotics should not be given during pregnancy.

Avoiding Unnecessary Antibiotic Avoidance
Dr. Paul cautions against the potentially perilous message that women should avoid antibiotics if they are trying to conceive.he clarifies: “The message should under no circumstances be that you should not use antibiotics if you want to have children. Regardless of whether you want to have children, this applies to bacterial infections that require treatment as well as to patients who want to have children in whom problem pathogens have been found in the vaginal swab.”
The message should under no circumstances be that you should not use antibiotics if you want to have children.
Dr. Wolfgang Paul
In cases of bacterial infection, appropriate antibiotic treatment is crucial, and delaying or avoiding it can have severe consequences. He states unequivocally: “if you don’t give antibiotics and let the infection get worse, then the patient will certainly not be able to conceive successfully.”
