Study population: We will be recruiting participants by the following means:

1. Posters within Imperial College NHS Healthcare trust
2. Advertisements within newspapers

5. Patients attending the Andrology Department and other reproductive outpatient clinics at Imperial College NHS healthcare trust

Brief summary: Study rationale

1. An increasing proportion of the worldwide population is being infected with COVID-19.
2. There are ongoing and currently unanswered safety concerns about the effects of COVID-19 on reproductive health.
3. 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.
4. The proposed study will be simple, rapid, and authoritative for the UK and worldwide.

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.

Eligibility criteria: Inclusion Criteria:

* Men currently self-isolating as per UK government advice for COVID-19 infection
* Needle-phobia
* Impaired ability to provide full consent to take part in the study
* History of co-morbidity likely to affect male reproductive function e.g. undescended testes, removal of testes, testicular cancer, drugs such as corticosteroids or testosterone therapy.
