In a great many fertility journeys, the man is tested last. Months of cycle tracking, hormone panels and ultrasounds happen first, and the semen analysis arrives as an afterthought once nothing else has explained the delay. That order is backwards, and it costs couples time they cannot get back.Male factor is involved in roughly half of couples who struggle to conceive. It is also the side of the equation that is quickest and cheapest to assess, and the side that tends to respond fastest to change.
Eggs are finite. Sperm are not. A man produces new sperm continuously, with each batch taking somewhere in the region of seventy to ninety days to develop and mature fully. That single biological difference is the most encouraging fact in this category, because it means the sperm in a semen analysis three months from now have not been made yet.
It also sets the timeline. Changes to diet, heat exposure, alcohol, sleep or supplementation will not show up in a test taken next month. They show up roughly one full cycle later, which is why any male fertility protocol should be given at least three months before it is judged.
A standard analysis reports concentration, motility, morphology and volume. Those numbers are genuinely useful, and a normal result rules out a lot. What they do not capture is DNA fragmentation, which measures damage to the genetic material inside the sperm and is not part of the routine panel in most clinics.
This matters because a man can return a normal-looking analysis and still have elevated fragmentation, which is associated with fertilisation and embryo development difficulties. If a couple has unexplained infertility, recurrent losses, or repeated poor embryo quality despite good egg numbers, fragmentation testing is worth raising with the clinic. It is one of the more common gaps we see.
Sperm production is sensitive to temperature, which is the reason the testes sit outside the body in the first place. Laptops on laps, long hot baths, saunas and prolonged cycling all raise scrotal temperature enough to matter over time. None of these is catastrophic and none needs to be treated as a crisis, but during a three month preparation window they are worth reducing.
Oxidative stress is the other recurring theme. Sperm cells are unusually vulnerable to oxidative damage because of their membrane composition and their limited internal repair capacity. Smoking, heavy alcohol use, poor sleep, obesity and environmental exposures all add to that load. This is the reasoning behind Rejoova Sperm, formulated around male reproductive support, and Rejoova Repair, which focuses on antioxidant and cellular support and is frequently taken with it. Neither treats a diagnosed male factor condition, and anything abnormal on an analysis belongs with a urologist or reproductive specialist.
Male fertility is usually discussed as though it holds steady while female fertility declines. The reality is less tidy. Sperm DNA fragmentation tends to rise with age, semen volume and motility gradually fall, and the time to conception lengthens even when a standard analysis still reads as normal. None of that closes a door, and men father children across a very wide age range. It does mean that in a couple where both partners are over 35, treating the male side as settled is a mistake worth avoiding.
An embryo is built from two cells, and the male contribution shapes fertilisation, early embryo development and miscarriage risk rather than simply getting things started. Because both halves run on a similar seventy to ninety day clock, preparing at the same time is far more practical than doing it in sequence. The egg health guides cover the other side, and the Fertility Support Bundle for Him or the Couples Fertility Support Bundle package the male protocol on its own or alongside hers. For the wider process, the trying to conceive section sets out what to expect at each stage.
The Part of Fertility Most Couples Miss I want to tell you something I see repeatedly in my practice, and it is something too many couples discover too late in their journey. Most couples come to me having spent months focused entirely on ovulation tracking, hormone testing, and egg …Read More
