About this study
Study rationale
- An increasing proportion of the worldwide population is being infected with COVID-19.
- There are ongoing and currently unanswered safety concerns about the effects of COVID-19 on reproductive health.
- It will be immensely reassuring to rapidly report that COVID-19 has no detectable effects on male endocrine or sperm function. Conversely, if COVID-19 does impair male reproductive health, appropriate screening can be performed in couples trying to conceive, and further research can be undertaken.
- The proposed study will be simple, rapid, and authoritative for the UK and worldwide.
Read the detailed description
Male infertility results from impaired sperm function, and account for half of all infertility. Fertility services have been reported to cost £325M annually in the UK(4) (REF). Testosterone deficiency is one of the most common hormonal problems affecting men, leading to osteoporosis, type 2 diabetes, obesity and depression(5).
Concerns have been raised about the potential effects of COVID-19 on male reproductive dysfunction (male infertility and testosterone deficiency). A recent study has suggested that COVID-19 may enter human cells by binding to receptors (special gates on cells that recognise a specific molecule) for angiotensin converting enzyme 2 (ACE2)(6) . ACE2 receptors are found at very high levels in the testes. Within the testes, ACE2 is found on developing sperm, the 'nurse cells' that help the sperm grow (Sertoli cells), and also on Leydig cells which are needed to make the male sex hormone testosterone. In summary, this evidence suggests that there is a plausible link why COVID-19 would cause male infertility and testosterone deficiency.
All fertility treatment in the UK is regulated by the Human Fertility and Embryology Authority (HFEA). The HFEA has prohibited on all non-cancer fertility treatment in the UK between April 15th and May 12th 2020 due to the COVID-19 epidemic. It is important to rapidly screen and report whether COVID-19 has any obvious effects in causing male infertility and testosterone deficiency. It must be noted that a recent study(1) reported that COVID-19 is not spread by human semen and therefore, semen processing should not risk staff to COVID-19 infection.

Questions about this trial
What is this clinical trial studying?
An observational study of Infertility, Male and Testosterone Deficiency, run by Imperial College London at 1 site in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 24 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Semen parameters (time frame: 3 visits (up to 75 days apart)). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04414904, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Nov 2020.
