Inclusion criteria
. Male volunteers, aged between 18 and 50 years inclusive, with a body weight of at least 50.0 kg, and a body mass index (BMI) between 19.0 and 28.0 kg/m² inclusive.
. Participants in the multiple dose phase must meet one of the following criteria: two routine semen analysis results during the screening period meet the criteria of sperm concentration of less than 15 million and/or percentage of progressively motility sperm of less than 32%.
. Participants (including the partners of the participants) must use effective non-drug contraceptive measures during the trial period and for four months after the end of administration, and must not have plans for pregnancy or sperm donation.
. Participants should avoid high temperature environments during the trial, including saunas, steam baths, hot baths, hot springs, and the use of electric blankets.
. Participants must give informed consent to this study before the study and voluntarily sign a written informed consent form.
Exclusion criteria
. Participants with a history of severe diseases, including but not limited to conditions affecting the skeletal, neuropsychiatric, cardiovascular, hematologic, hepatic, renal, gastrointestinal, respiratory, metabolic, endocrine, immune, and reproductive systems (such as reproductive system infectious diseases, varicocele, reproductive tract obstruction, etc., except for oligoasthenzoospermia), as judged by the investigator, may endanger the safety of the participant or affect the study results.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Number of treatment-related adverse events as assessed by CTCAE 5.0.
Timeframe: 85 days in multiple dose phase and 28 days in single dose phase
. Participants who have planned to receive treatments related to oligoasthenzoospermia, such as zinc sulfate, levocarnitine, escin, or pancreatic kallikrein, within 3 months prior to screening or during the trial period.
. Participants with a history of treatment with nerve growth factor-like drug therapy (such as mouse nerve growth factor for injection) within 3 months prior to screening.
. Participants who have undergone any major surgery within 3 months prior to screening or have surgery planned during the trial period.
. Participants who have experienced a fever exceeding 38 ℃ within 1 month prior to screening
. Pre-enrollment physical examination, electrocardiogram, vital signs, laboratory tests, and results of all tests related to the trial (except oligoasthenzoospermia), with abnormalities judged clinically significant by the investigator.
. Participants who are allergic to any component of the experimental drug or biological agent, or who, in the judgment of the investigator, are at risk of allergy as a result of participation in the study.
. Participants who are positive for any one of the hepatitis B surface antigen, hepatitis C antibody, treponema pallidum antibody, and HIV antigen/antibody combination test (primary screening).
