Female volunteer donating blood in a medical setting.
India needs 14.6 million units of blood every year.
3.3 million of those units — more than 22% of the total — go to obstetrics and gynaecology. Mothers haemorrhaging during childbirth. Pregnant women with severe anaemia. Women with gynaecological cancers and reproductive complications.
The largest single population of blood recipients in India that is exclusively female accounts for nearly a quarter of all blood demand.
And yet, in the same year, only 6% of India's voluntary blood donors are women.
This is not just a gender equity issue. It is a structural vulnerability in India's blood supply system — and it costs lives in ways that the national blood collection data does not fully capture.
The figures are stark. A retrospective study of 45,067 donors at UPUMS Blood Centre in rural Uttar Pradesh (2018–2023) found that 97.6% of donors were male and only 2.4% were female — an extreme but not unrepresentative reflection of the national picture.
Even in urban, more gender-equitable settings, the imbalance is significant. A study from a South India blood bank found that female donors constituted only 11.27% of total donors.
A 2025 narrative review published in PubMed noted that globally, women contribute only around one-third of donations — and in some countries (India among them), their involvement is well below 5–10%.
Men in India do not donate at adequate rates either. But the near-total absence of women from the donor pool creates a specific kind of fragility: a system that serves women's healthcare needs at enormous scale but draws almost none of its supply from women.
The reasons women donate blood less frequently in India are multiple, well-documented, and — importantly — not primarily about willingness.
The most significant single barrier is anaemia — low haemoglobin. India has among the world's highest anaemia rates in women: an estimated 50–60% of pregnant women are anaemic, and high rates persist in the general female population.
To donate blood, a minimum haemoglobin of 12.5 g/dL is required. Anaemia accounts for up to 77.9% of female deferrals — compared to 37% of male deferrals. This means that a woman who genuinely wants to donate blood is turned away nearly four times more often than her male counterpart, often for a condition that is itself a public health failure rather than a personal health choice.
This creates a painful irony: the women most likely to understand the need for blood (because they have experienced health system failures first-hand) are the least able to donate because of inadequate nutrition and healthcare.
Beyond physiology, social factors restrict female donation in ways that are harder to measure but equally real:
The consequences of female under-representation in blood donation are not abstract.
1. The obstetric blood gap: The 3.3 million units needed annually for obstetric care must be drawn from a donor pool that is over 90% male. There is nothing physiologically wrong with this — blood is blood, regardless of donor gender. But it creates a structural mismatch in social responsibility. Women are the primary recipients of obstetric blood — and their near-absence from donation means that men are exclusively responsible for supplying a health resource that primarily serves women.
2. Smaller overall supply: Women represent roughly half of India's 402 million eligible blood donors. If female participation rose from 6% to even 20% of total donors, this would add millions of units to the annual supply — enough to close the one-million-unit annual shortage multiple times over.
3. Loss of female-to-female solidarity: Research shows that knowing a donation will help someone in a similar life situation is a powerful motivator. Women who understand that their blood goes to mothers in haemorrhage, to girls with thalassemia, to women with gynaecological cancers — this connection, when communicated explicitly, significantly increases female donor motivation.
The most practical intervention for closing the female donation gap is addressing anaemia. Women who receive iron supplementation advice after a deferral, and who are supported in returning when their haemoglobin has recovered, convert at higher rates than those who are simply turned away.
Some blood banks already offer nutritional guidance after deferral. Scaling this — combined with broader public health efforts to address iron deficiency in women — would meaningfully expand the female donor pool.
Campaigns that address the specific myths and concerns women face — about menstruation, fertility, weakness, and family permission — are more effective than generic blood donation awareness. Messaging that directly counters "menstruation disqualifies you" and "it affects your fertility" needs to reach women where they are, in their language, through their trusted information sources.
Women are significantly more motivated to donate when a trusted peer or community leader they know has donated. Female role models in blood donation — visible, celebrated, named — create permission for other women to follow.
Blood donation drives that specifically invite and encourage female participation — with dedicated registration times, female phlebotomists available where requested, and explicit messaging about eligibility — show higher female participation rates than generic invitations.
For women in contexts where family permission is a barrier, campaigns that engage husbands, mothers-in-law, and community leaders in understanding and supporting female donation can shift the social landscape over time.
A woman who is menstruating can donate blood — provided her haemoglobin meets the 12.5 g/dL threshold on the day of donation, she feels well, and she has no unusual symptoms.
There is no medical rule against donating during menstruation. The physiological blood loss during a normal menstrual cycle is approximately 30–80 ml — significantly less than the 350–450 ml of a blood donation. The two events are additive in terms of iron loss, which is why haemoglobin is checked individually before each donation.
Women who feel unwell during menstruation may choose to wait a few days — but this is personal preference, not medical requirement.
TheBloodApp is built for every eligible donor — regardless of gender. Women who register, donate, and respond to urgent alerts are part of the same network as every other voluntary donor. Their blood type, availability, and location are searchable. Their participation matters.
The goal is not female representation for its own sake. The goal is the largest possible pool of voluntary, regular, eligible donors contributing to India's blood supply year-round. Women are half of that pool.
Register on TheBloodApp today. If you are a woman between 18 and 65, weighing at least 45 kg and in reasonable health, you are likely eligible to donate. Your haemoglobin will be checked before each donation. If your haemoglobin is too low today, eat more iron-rich foods and return in a few weeks. To find a blood bank or donation camp near you, call the number listed in the app.
